So we will see you back here for a live text from 07:00 BST I take it? Good.
Thank you for all the interaction on Friday. What a tournament this is shaping up to be. So many in touch with the lead and conditions which look sure to cause turmoil.
I'll leave you with this...

Sir Nick Faldo - three Open Championship wins but no longer will he walk the fairways in the grand competition. It would appear he is going to toast his own success.
See you tomorrow.
Watson's farewell
Tom Watson speak to BBC Sport: "Last year I asked the R&A if they would grant me one more year of exemption for this old guy to walk the Old Course in an Open Championship for my last, it didn't take long to say they would love to have me. I do feel very thankful for this place is special, the history of St Andrews is documented, its goes back 400 years and will always be the golf course people think about when they think of links golf.
"It has been a very special time in my life, I am 65 years old and it has been a great run since 1975 when I played across the links at Carnoustie. There are moments and memories that will be remembered."
Where is Jordan Spieth?
If you did not managed to catch it amidst all of the Tom Watson fever, Jordan Spieth, Dustin Johnson and Hideki Matsuyama all finished on the par-five 14th hole. They will finish that stretch tomorrow morning.
Spieth and Matsuyama at five under and six under respectively, have work to do to catch Johnson on -10.
Watson's farewell
Tom Watson speaks to BBC Sport: "It was wonderful to have that final walk in front of a lot of people who I hope that I touched over the years of playing and have showed them some shots they were in awe of.
"When I was a kid that was one of ways I would get out of shyness, I would hit a shot and get praise from people. I carried that on into my professional career. Today I didn't give them many good shots and I am disappointed from that standpoint but it was a pleasure to have people cheer me on during my whole round of golf today was very special."

"Tom Watson will always be top of mind when you remember the greats of golf. They've loved him here. He made a winning debut 40 years ago at the age of 25 but we say farewell and thank you, Mr Watson."
Sometimes you can become so immersed in the marathon that is a golf major that moments like this wash over you and don't quite bite for what they are.
Watson is in for a bogey but who cares. A smiler, a gentleman, a winner, an Open Champion five times over.

This moment has been 38 years in the making. In that time we have seen him clasp the Claret Jug five times. Few, if any, are to this tournament what Watson is. Thanks Tom.
Watson on the home straight
Watson +11 (17)
BBC SportCopyright: BBC Sport
Tom Watson receives a warm welcome as he walks up the 17th, surely he will finish his round tonight.
A bogey on 17 hasn't stopped him yet and he walks to 18 where we think the hooter will sound after his tee shot, thus allowing him to finish his round and amazing relationship with The Open tonight.
Double bogey
Snedeker +3 (17)
Brandt Snedeker needs a birdie to get near the cut, he is currently one over par. The American uses what he calls a 'pop stroke' to get the ball rolling quickly, it's not a conventional putting technique.
This one rolls way too far and it won't even be par. That is probably the end of his weekend hopes.

Tiger Woods, Jason Day and Louis Oosthuizen say enough is enough on the 12th green. A good day's work for all but Tiger. They will have six holes to conclude first thing in what we expect to be very tough conditions. Sleep well boys.
Not everyone is finished...

Johnson -10 (13)
Interestingly, if we get one more hole in, Dustin Johnson has just flown a missile down the 14th fairway and it is a par five. Two-shot lead overnight anyone?

Finish if you want...
the latest from the course is that players can stop if they want to and some are apparently very keen. However, those that want to continue can do so and if one group stops, others don't necessarily have to.
Glad that's clear. Now let's crack on lads, it's Friday and we want to be entertained.

"The touch has deserted Matsuyama. He will be quite keen to get in for a bit of sushi."
The Japanese player leaves a putt well short on 13 and his run of seven birdies in 10 holes seems a while ago now. Bogeys on 11 and 12, probably par here.

Official line from the R&A on when play will stop, though no time has been given yet.
"Discussions are ongoing whether the course is playable, some of the players are asking. Once play is suspended and the hooter is blown if a player is in the course of playing a hole they can continue until the end of the hole and then stop."
Sounds like a quick process. It's not like time is ticking.
Post update
Luke Donald on 18, looking to haul back a stroke lost on the last. This drag of course offers up chances galore and it's just a short wedge to set up a birdie chance is it... no. He didn't judge the length needed and gets no luck as the ball pitches. A tough up and down for par now.
WOOSH as Jason Day, Louis Oosthuizen and Tiger Woods tee off down 12. Night vision goggles needed for their wedge shots.

This is a man glaring at his playing partners and saying he can see little in the light.
BBCCopyright: BBC
A par will have to do Louis Oosthuizen at the 11th and an early alarm clock will fluster him briefly tomorrow. Jason Day also makes par there to stay at eight under.
If you want to see just how dark it is, you can watch the action on the 'Live Coverage' tab at the top of this page.
Bogey
Donald -7 (17), Matsuyama -5 (12)
Louis Oostuizen is trundling along nicely at seven under alongside Tiger Woods who can only dream of such a score. The pair go pin seeking at 11 but the par three is not setup for such frivolity and their shots trickle away to leave lengthy birdie putts.
Suddenly things look tougher, the prolific birdies of earlier have turned to a trickle and Luke Donald makes bogey on 17 to slip back to -7. He will at least finish his round. Matsuyama... the birdie machine... bogey on 12. Ugly putt.

Spare a thought for Tom Watson. In a beautifully crisp sky-blue jumper he stands out even in the dwindling light.
This is a man playing his final few holes ever in The Open. At nine over, the weekend will not be lit up with his presence but will he be forced to finish tomorrow? Just three holes to go but the emerging darkness may stop him in his tracks.

Bogey
Johnson -10 (11), Matsuyama -6 (11)
Another miss. Another bogey. The first of the week for Dustin Johnson. It took him 29 holes but there it is. The big hitter, like Spieth, is hurt by the par three. Twice he stepped back from his putt as the wind unsettled him. Third time lucky, no way. Lips out.
And just as the three players have followed one another in carding birdies, now they complete the full house of bogeys as Hideki Matsuyama putts a bad number '4' on his card.
Bogey
Spieth -5 (11)
Do the winds bring a change?
BBCCopyright: BBC
The tee shot which left Scotland landed Jordan Spieth in too much trouble to handle and this is the ice-cool man - wearing a beanie hat - and getting very angry.
His trousers were gusting around his shins in the wind and the six-foot par putt was not good enough, back to five under.
Dustin Johnson now...
Testing moments
Johnson -11 (10), Spieth -6 (10)
Jordan Spieth has found trouble. Today has been far from smooth for him but he needs to iron out these imperfections if he is to prevent Dustin Johnson from pulling away.
Spieth's tee shot on 11 was so wide it almost landed back in Texas and he now has to get up and down on the par three. He elects to putt and the ball covers a serious amount of real estate to land around six feet shy.
Dustin Johnson is better placed, his par putt will be around four feet.
"When they call time for the night players do have the option of finishing the hole they are playing so there will be some mad dashing to the 18th tee for some."
Those who cannot finish must come back at 07:00 BST on Saturday.
I'm getting sick of birdies
Dustin Johnson is in for birdie on 10 and looks unstoppable. Maybe Luke Donald is the man to put up some resistance. The 37-year-old produces a firework of a putt from serious distance for another birdie.
BBCCopyright: BBC
Apologies if you think this is repetitive but the word 'birdie' is all I'm typing. Paul Lawrie... yes, birdie again. Eight under alongside Donald and Jason Day. I almost feel sorry for The Old Course. We need a bogey just to straighten things out a bit.

That's incredible!
This is ridiculous. Can someone arrest Hideki Matsuyama for crimes against reality. Just as we think his run of birdies is over he putts up and over a slope, from left to right and back down a slope for a glorious seventh birdie in 10 holes.
SEVEN IN 10. Enough is enough.

What a shot!
Driver, wedge, putter. Driver, wedge, putter. Dustin Johnson needs just three clubs in the bag.
This left for birdie on 10.

His power is stunning and this will surely be 11 under and a healthy two-stroke lead. What hole on this course can tame him?
Jordan Spieth makes par on the same hole.
I ain't afraid of no rain...
And we have drizzle. This was supposed to be torrid today. Come on, it's not that bad. What are you guys? Fair weather players?

Dustin Johnson pushes his birdie attempt wide and will turn three under for his round, 10 under and leading overall.
But take a breather, absorb your surroundings, this is now looking stacked with talent. They are lining up behind him.
BBCCopyright: BBC
Jordan Spieth and Hideki Matsuyama do what Johnson couldn't on nine to move closer. Luke Donald rolls one in on 13 and is just three back while Charl Schwartzel - a major champion of the past of course - moves to eight under.
Birdie
Oosthuizen -6 (7), Day -7 (7)
Be prepared for more change at the top. Dustin Johnson, Jordan Spieth and Hideki Matsuyama have pulverised this short par-four ninth and will have very, very makeable birdie putts.
Louis Oosthuizen is over a long and rapid putt for birdie on seven... it's in. Can Jason Day follow his playing partner? Yes he can. Seven under for Day, one better off than Oost.

Spieth -5 (8), Johnson -10 (8)
The Jordan Spieth putting machine isn't quite fully oiled yet and his slider on eight yields bogey. Not a long one, perhaps 12 feet but didn't threaten the hole.
The US Open and Masters champion is back to five under, five adrift from Dustin Johnson who crushes a tee shot down nine. The ninth hole has a great name 'End.' There's a finality to the name which is scary.

Hideki Matsuyama is 51 places up on where he started this morning. Frightening. He is 23 and already has a big PGA Tour win to his name at Memorial last year.
Birdie
The birdie train is running through your computer/mobile/tablet, get on board.
Hideki Matsuyama - a serious hope for a major title in Japan - is making a mockery of things. This is frankly absurd. A fifth birdie in seven holes as his long putt settles in the cup.
Dustin Johnson, playing alongside Matsuyama and Spieth - boom. New leader. What about Retief Goosen on 13? You know what's coming... birdie.
Goosen now shares third on seven under with Adam Scott, Charl Schwartzel, Zach Johnson and Marc Warren.
Birdie
Spieth -6 (7)

"Don't top it into the sand, don't top it into the sand, don't top it into the sand." I think we've all faced these chips.
You won't be surprised to know Jordan Spieth didn't. Instead he nearly holed this wedge but now has a go for birdie and six under. It's downhill from 10-12 feet, minimal break, dribble... roll... drops.
Suddenly, there are birdies everywhere...

"Luke Donald has played beautifully so far... until now," says Peter Alliss.
Donald leaves a birdie putt well short on 12. Jason Day on five for par... yes, he had to make that from close range though par is not really much to shout about there. Quickly back to Donald for his par... what have you got? Plenty. In she pops.

The amateur of amateurs at St Andrews - Paul Dunne - has a whacky putting grip. It looks like he has a finger down either side of the grip. It doesn't get the job done on 16 as he makes bogey to drop one. A pushed putt from four feet.
Spieth for birdie on six, left to right, six feet... drained. Johnson makes par. Will Dustin be steady until the final hole on the final day. Chambers Bay all over again?
What a shot!
Spieth -4 (5), Garcia -2 (7)
Jordan Spieth, recovering from bogey on the easiest hole on the course, what has he got. Wow. Stuffs one to within a few feet on six. Massive birdie chance.
And can I have a fist pump please Sergio? Yes I can. Mr Garcia judges a putt beautifully as it drops in the front of the cup on seven for birdie and two under.

Birdie
Donald -6 (11)
Louis Oostuizen wants to play one-handed golf does he? Lashes one down the fifth but lets go of his club. Ball safe. Lucky boy. The former champion is back to four under and needs to take this par-five drag for all it's worth.
BBCCopyright: BBC
What for Luke Donald, wearing the customary visor. Not sure where I stand on a visor, I guess it prevents premature baldness from too much hat usage. He looks the part and plays the part lately. His ball settles underground and that is two under for the day and six under overall. not bad when you consider he started the round with a double bogey.
Birdie
Dunne - 6 (15)
Heard the one about the amateur who rocked up and challenged for The Open?
His name is Paul Dunne. Irish lad. Just birdied 14 and 15 to move six under. He's 22 after all. It must be those years of experience showing through.
"A different wind direction for Jordan Spieth to deal with today and it adds a whole new dimension to this course."
Birdie
Spieth -5 (5), Johnson -9 (5)
Jordan Spieth has this monster for birdie on five...
BBCCopyright: BBC
He putts, from left to right and the ball briefly leaves the putting surface, through the fringe, it will stop short but with six feet left, that is practically a gimmee for Spieth. The kid sinks those with his eyes closed.
Dustin Johnson two putts from 30 feet or more and that will be birdie and a share of the lead with Danny Willett.
Back to Spieth, downhill... NO. Pulled it. Well I never. Check his pulse. That leaves him five adrift of the co-leaders.
Plan for tomorrow
John Murray
BBC Radio 5 live commentator
The plan is to start at 7am tomorrow and finish the second round by 10am, then begin the third round at 11am with three balls.
Ouch!
Schwartzel -6 (6)
It's sunny one moment, dark and cold the next, what the heck is going on in the sky?
Charl Schwartzel tosses one up there, does it come down with water on it or heat? It's come down alright but he may have to dig for that one, buried in some rough near the green. He looks confused. This would be an audacious up and down to escape punishment,

Eagle putts on five
Johnson -8 (4), Spieth -5 (4)
Be prepared for Dustin Johnson to tie the lead. He is on the par five fifth hole where shots get collected by players like a pub landlord collects hangovers.
Where as many players have to bludgeon their ball to reach the green, Johnson flicks one and will have a long, long put for Eagle. Now Spieth... same result. Putting from Gibraltar but an eagle attempt nonetheless.

"It was all about standing on the bridge and I wanted to bust out my old jumper. It would have been stupid to miss that. I am dying to make the cut but I am 58, I play once a year and there are kids less than half my age out there. If that is the last walk I will be really happy."
Bogey

Jason Day has been in real trouble on the second after a birdie at the first. Finding the bunker off the tee, he has to produce a stunning chip and run to stone dead from off the green to rescue a bogey five. It could have been worse.

Another missed opportunity for Dustin Johnson. Four feet for birdie on three but he pushes it past and another par... No such problems for Luke Donald who birdies eight and moves to four under...

"By the I time teed off it was just the wind to deal with, it was pretty dry by then. Obviously it was a great feeling to birdie the last hole at St Andrew's. My game is in good shape and I have hopefully put myself in contention. I will give it my best and see what happens."
"Tiger's got his game face on, he's not waving to the crowd in a jocular fashion. Serious stuff."
Forget about his face, he needs to get his game together. A weak putt for birdie but at least he saves par on the first. Jason Day birdies the first and is up to seven under.

From one legend to another. Tiger Woods is on the tee, looking to put yesterday's nightmare behind him. He is currently tied 127th after a four-over-par opening round. A 68 would get him into the weekend. What are you made off Tiger? No problems off the tee as he strides maningfully on.
"That's a nice touch from player partners still very much playing in this championship, but who would deny Faldo that moment? A great former champion at St Andrew's."
"Faldo's a wonderful champion who did some great things. A short career really at the top of the tree, he didn't go on like some but some magical moments. He's bathed in sunshine and adoration."

Faldo (+10 after 18)

It's all about Sir Nick Faldo for the moment though as he receives another ovation onto 18. About 12 feet for birdie for the three-time Open winner but there is no dream ending. He pushes it a few feet past and is left a nasty one for par.
Justin Rose for birdie from six feet... is it? No, he hangs his head in disappointment, but he will take that round. Four under for the day and five under for the Championship - well in contention.
Faldo has the last word though as he holes his clutch putt for par before raising both arms aloft. St Andrews says farewell. It has been a pleasure. (Good news for him too... he isn't last any more. Mark Calcavecchia and Ben Taylor are one behind).

Sir Nick Faldo is making the most of his last walk down the 18th at St Andrews. He pulls on the jumper he wore back in 1987 when he won The Open at Muirfield before posing for photos and waving to the crowd. Playing partners Justin Rose and Rickie Fowler get in on the act as they put their arms around him on the bridge. Emotional stuff. "Still fits after 30 years"... says Faldo.
Birdie
Lingmerth (-5 after 9)
David Lingmerth. Remember his heroics yesterday... for the first nine at least. He went out in 29 on Thursday and he has impressed on the front nine again. He birdies nine to go two under for the day and five under for the championship. Steady scoring by the Swede.

Adam Scott on BBC TV: "I'm really happy with that. Any time you can have a round without bogey is pleasing. I just chipped my way round. It was not easy or hard, just a sideways wind all the way around.
"I had a big preparation the week before I played here, not wind like this but you have to chip the ball along the ground. Just thinking about (narrowly missing out on winning The Open in 2013) makes me motivated. I know the feelings and that is all great experience for me. Hopefully I will have a chance by the time I get to the last nine on Sunday."
Birdie
Faldo (+10 after 17)
PACopyright: PA
Arise Sir Nick. Faldo brings the crowd to their feet on 17 with just the fifth birdie of the day on the notoriously difficult hole. He sinks an uphill putt from off the green. Brilliant. That moves Faldo to one under for the day - on what is his last Open at St Andrews - but hopes of making the cut are long, long gone. Good to see the magic is still there though.
"The Masters champion, the US Open champion, can he become The Open champion?"
On the first
Spieth, Johnson, Matsuyama,
Getty ImagesCopyright: Getty Images
Here we go then. Jordan Spieth on the first as he continues his bid to become just the second man to win the first three majors of the year. He is in a decent position on five under. No nerves from the American as he lands safely on the fairway. Overnight leader Dustin Johnson has watched Danny Willett set the pace, how will he respond? A driving iron down the right. He is on seven under.
A huge roar is heard from somewhere...
Triple bogey
Kuchar (E after 17)
Just a bit more welly Phil... Mickelson misses a birdie putt by inches on the 17th. His charge has stalled as he stays on three under.
Talking about stalling, Matt Kuchar is in real trouble after a treble bogey on 17. He finds the Road Hole bunker with his first, then thins it over the road and takes three shots from there. Back to level and in danger of missing the cut.

That's incredible!
Chesters (-1) (15)
Ashley Chesters - one of the amateurs in the field - has just dropped a freakish putt across the 15th green to make birdie and return to one under par.
It's so long we can barely fit him and the hole (next to the player's head bottom left) into shot.

Ireland's Paul Dunne - another amateur - is four under, while Jordan Niebrugge of the US is on the same mark. Remember the leading amateur wins the silver medal honour.
Post update
Poulter (+2 after 1)
Ian Poulter hasn't made a great start. A five at the first before leaving his approach on the short well short of the green. A tough evening for Poults ahead?
Meanwhile Jordan Spieth and Dustin Johnson are warming up on the putting green. They tee off in about eight minutes time on five under and seven under respectively.

Bubba Watson pars the first and stays on one under. He needs a charge today.

Rickie Fowler should be among the leaders but he has missed birdie putt after birdie putt. The Scottish Open winner has given himself so many solid chances but nothing - and I mean nothing - is threatening the hole.

Rose -5 (16)
Birdie, birdie, birdie, birdie for Justin Rose... no, not quite. He whistles a putt from somewhere on the outskirts of Middlesbrough which goes just past. It will be par and he will have to stick on five under. Tough 17th drag next, then a phenomenal birdie chance on the last. The 2013 US Open winner is in great shape.

12 groups to go
Shaping up nicely now this. By my counting we have 36 players left to begin their rounds.
In around three hours we will begin to know if the morning hitters have done enough or will their efforts get swallowed up by some big names?
The cut by the way is currently at one under but some wise money is on that slipping back to level par.
"Within two of Danny Willett, Adam Scott is poised to strike over the weekend."
Birdie
Scott -7 (18), Walker -4 (18), Kaymer -3 (18)
The 18th hole - a drivable par four - is giving up shots like Santa gives out presents today. The three ball of Adam Scott, Martin Kaymer and Jimmy Walker all capitalise and all three are inside 10 feet for birdie.
This is Adam Scott's ball and that is a tap-in birdie and seven under.
BBCCopyright: BBC
Can Kaymer follow suit, he slides one in by the thinnest of margins. What now for Walker - lovely weight - a hat-trick of birdies.

England's Tyrrell Hatton tees off at 19:05 BST...
Birdie
Rose -5 (15)
Justin Rose fires an absolute worldie of an iron down the flag at 15 to leave just a few feet for birdie on a hole which has not given much up today. Indeed, it's the fourth-toughest hole on the course in round two.
Rose makes mince meat of it and can he capitalise with the birdie putt... no problems, five under par. In strong contention.
Race for silver
PACopyright: PA
A solid round from Irish amateur Paul Dunne so far, with pars on the first seven holes to keep him at three under and in a shared lead for the silver medal. Tied with him currently is American Jordan Niebrugge, who has dropped two shots after his five under opening round.

Bogey
Mickelson -3 (15)
Phil Mickelson is a yo-yo today. He's up he's down, his putts are in then out, make up your mind Phil and go with it. A nervy putt on 15 is badly wide and that is bogey.
That's three shots given away on this back nine. An 'oh what might have been' round is forming here.
Post update
Scott -6 (17)
It may not have escaped your attention that Adam Scott has surged the leaderboard today and did pretty well at the US Open in June too.
But have your eagle eyes picked up on the fact the man on his bag is familiar?
Getty ImagesCopyright: Getty Images
Steve Williams - who looked after Tiger Woods's bag from 1999 to 2011 and then moved to work with Scott - was no longer in the caddying game and until recently, lived a rural lifestyle in his native New Zealand.
"Steve was adamant that he was not going to caddie in 2015, so he took some convincing, but I am very happy he's agreed to help out," Scott said.
The pair will be working together for the majors and it seems to be doing the business.
Post update
Scott -6 (17)
Mark James
Former Ryder Cup captain on BBC TV
"Adam Scott looks back to his best in America. He could be a real contender this week."
Birdie
Rose -4 (14)
If you are just joining us, the horrid 17th hole is playing slightly - and I do mean slightly - easier today. It is now home to Adam Scott, currently six under, and he needs to find the right of the fairway to be best placed. Nails it with driver and could not have placed it better.
What about Justin Rose? He is going about his business doggedly and has been all day. The 34-year-old pounces on a par five to make birdie. That is birdie on 13 and 14 for him and four under overall.
"The cameras are gathering around the first and why not? One of the great, great champions is Tom Watson, who has won this Championship five times, is there. Members gather in the window to watch the old boy drive off, maybe for the last time.
"Watch the swing when he drives, the length, the fluidity of it and marvel at the fellow. It won't be long before he gets his bus pass - but it is truly remarkable how easy he makes it look."

The last time we see Tom Watson on the tee at The Open? Possibly. Although at +4, he will hope he has at least two more rounds left in him after this... Safely off the first.
Redknapp on Watson
Watson (+4)
Former Tottenham manager Harry Redknapp has paid tribute to five-time Open winner Tom Watson ahead of the second round.
"Tom Watson is a fantastic sportsman and it will be emotional to see him walk over the Swilcan Bridge for the last time," writes Redknapp. "I saw him win The Open at Troon and even when he was in the heat of battle he made sure he smiled at the spectators and took time to acknowledge them. He's a true gentleman and a fantastic golfer and I thought it was a real shame he got some stick after last year's Ryder Cup, he didn't deserve that."
A final farewell?
Watson (+4)
.Copyright: .
A forty year love affair with the Open Golf Championship is coming to an end - possibly.
Tom Watson first played in the Open in 1975, won it five times and remarkably came close to a sixth as a 60-year-old in 2009.
This week he teed off for the final time - we expect - and what better place to do it than at St Andrews - recognised the world over as the home of golf.
So the BBC's Alex South thought he'd fire in a quick round of his own with Watson. Watch here.
Watson tees off
A five-time winner and on his 38th Open outing, here comes Tom Watson.
Getty ImagesCopyright: Getty Images
Will this be his last opening tee shot at a competition which where he will forever be fondly remembered?
Birdie
Stenson -1 (14), Mickelson -4 (14)
Henrik Stenson makes par on the par five 14th, a wasted put gets pushed past. Much like Rickie Fowler today his work is good until he gets within 10 feet of the cup. Phil Mickelson can only make par after using his bucket and spade from the bunker but this lot can wait for a while, we are probably about to see the final opening tee shot from a legend in the Open...
"You can almost smell the rubber burning when he hits a driver."
Overnight leader Dustin Johnson is on the range but he still has some time to wait, not teeing off until 17:48 BST due to the rain delay earlier today. He will be chomping at the bit...
Stat attack

No doubt the opening nine proved easier yesterday. Will the afternoon guys get a tough few hours as they did yesterday?
"The scoring has been excellent when you think of the weather predictions and the way things looked at 7:00 BST. There's been some wonderful scoring. I thought the qualifying score would be well over par. But still, a long way to travel. It has been remarkably good."
Bogey
Goosen -5 (1)
What is this? Retief Goosen follows Luke Donald up the first and it is dismal stuff. A bogey, not quite as bad as Donald but maybe a precursor? Conditions stiffening?
ReutersCopyright: Reuters
Ouch!
Mickelson -4 through 13
Anyone else get nervous when a pro takes driver off the fairway? It's such a risk-reward play and Phil Mickelson will wish he hadn't bothered when he walks up the 14th fairway. After an almighty whack, his ball runs and runs into a sand trap near the green. You are all wise enough to know that bunkers here are around 10,000 feet below sea level.
Double bogey
Donald -2 (1)
Poor old Luke Donald, such a friendly face. He probably felt elated waking up this morning at four under going into round two. There's nothing like a double bogey on the first hole to deliver a hard right hook into the rib cage. Pick yourself up and dust yourself down Luke, go again.
Jimmy Walker of the US has caught a bit of the Donald shakes, missing a similar short putt for par on 15. Walker will slip to three under. Walker is some player, only Jordan Spieth above him in the PGA Tour's Fedex Cup rankings.

Birdie
Mickelson -4 through 13
If you are just joining us Phil Mickelson carded a double bogey on the 11th hole which ruined some super early work but he is back on kilter, sinking this little tester on 13 to make birdie and four under.

Johnson content wit seven under
.Copyright: .
Zach Johnson speaking on BBC Two after finishing on seven under: "I had a couple of three putts but all in all I am pretty happy. Great rhythm, play athletic and hit your shot. There is a lot to be said about that."
A lot to be said for his round indeed. Johnson has already won a major remember - the Masters in 2007.
The ultimate barometer
American golf writer Doug Ferguson...
Birdies
Kaymer (-2), Streb (-7), Ogilvy (-5)
The projected cut is around level par at the moment but may slip back as conditions get tougher. Germany's Martin Kaymer is well inside the line as he makes birdie on 14 to move two under.
What is this on second? Robert Streb of the US is into a share of second place as he sinks a bomb from 20-30 feet.
And this birdie train is unstoppable, Geoff Ogilvy at the wheel on 18. "All aboard, all aboard", five under for the Australian.
Gusts and gusts
Ben Dirs
BBC Sport at St Andrews
"A weather forecast from the course: Chance of a few showers, especially later, but they should tend to move through quite quickly on the wind. Wind increasing to 20mph, gusting to 30mph later.
"Saturday: Very windy. Chance of showers to start the afternoon but becoming drier and brighter with increasing amounts of sunshine through the afternoon and into the evening. Winds 20-25mph with gusts 30-40mph. Gusts should start to ease into the evening."

Birdie
Willett leads on nine under
.Copyright: .
This could be a key moment for Danny Willett on 18. After a couple of dropped strokes late in this round he has this 10 footer for nine under and a two-stroke lead. All in black, he stands over it, sets it on its way... never in doubt. A crisp putt and an Englishman leads The Open Championship.
His 69 was rock solid. A minor wobble but not even Harry Houdini could escape this course unscathed.
The hardest hole

Things are proving a little easier today on 17 though as Thongchai Jaidee and Geoff Ogilvy nail putts from distance for the third and fourth birdies of the day on that hole. Better than the big fat zero from yesterday.

Sir Nick Faldo - three Open Championship wins but no longer will he walk the fairways in the grand competition. It would appear he is going to toast his own success.
See you tomorrow.
Watson's farewell
Tom Watson speak to BBC Sport: "Last year I asked the R&A if they would grant me one more year of exemption for this old guy to walk the Old Course in an Open Championship for my last, it didn't take long to say they would love to have me. I do feel very thankful for this place is special, the history of St Andrews is documented, its goes back 400 years and will always be the golf course people think about when they think of links golf.
"It has been a very special time in my life, I am 65 years old and it has been a great run since 1975 when I played across the links at Carnoustie. There are moments and memories that will be remembered."
Where is Jordan Spieth?
If you did not managed to catch it amidst all of the Tom Watson fever, Jordan Spieth, Dustin Johnson and Hideki Matsuyama all finished on the par-five 14th hole. They will finish that stretch tomorrow morning.
Spieth and Matsuyama at five under and six under respectively, have work to do to catch Johnson on -10.
Watson's farewell
Tom Watson speaks to BBC Sport: "It was wonderful to have that final walk in front of a lot of people who I hope that I touched over the years of playing and have showed them some shots they were in awe of.
"When I was a kid that was one of ways I would get out of shyness, I would hit a shot and get praise from people. I carried that on into my professional career. Today I didn't give them many good shots and I am disappointed from that standpoint but it was a pleasure to have people cheer me on during my whole round of golf today was very special."

Windy day in store...

We are officially done for the day but players can finish the hole they are on. It's time for some Tom Watson posing on the Swilcan Bridge. The applause rings out.
This moment has been 38 years in the making. In that time we have seen him clasp the Claret Jug five times. Few, if any, are to this tournament what Watson is. Thanks Tom.
Watson on the home straight
Watson +11 (17)
Tom Watson receives a warm welcome as he walks up the 17th, surely he will finish his round tonight.
A bogey on 17 hasn't stopped him yet and he walks to 18 where we think the hooter will sound after his tee shot, thus allowing him to finish his round and amazing relationship with The Open tonight.
Double bogey
Snedeker +3 (17)
Brandt Snedeker needs a birdie to get near the cut, he is currently one over par. The American uses what he calls a 'pop stroke' to get the ball rolling quickly, it's not a conventional putting technique.
This one rolls way too far and it won't even be par. That is probably the end of his weekend hopes.

the latest from the course is that players can stop if they want to and some are apparently very keen. However, those that want to continue can do so and if one group stops, others don't necessarily have to.

Luke Donald on 18, looking to haul back a stroke lost on the last. This drag of course offers up chances galore and it's just a short wedge to set up a birdie chance is it... no. He didn't judge the length needed and gets no luck as the ball pitches. A tough up and down for par now.
WOOSH as Jason Day, Louis Oosthuizen and Tiger Woods tee off down 12. Night vision goggles needed for their wedge shots.

Oosthuizen -7 (11), Day -8 (11)
This is a man glaring at his playing partners and saying he can see little in the light.
A par will have to do Louis Oosthuizen at the 11th and an early alarm clock will fluster him briefly tomorrow. Jason Day also makes par there to stay at eight under.
If you want to see just how dark it is, you can watch the action on the 'Live Coverage' tab at the top of this page.
Bogey
Donald -7 (17), Matsuyama -5 (12)
Louis Oostuizen is trundling along nicely at seven under alongside Tiger Woods who can only dream of such a score. The pair go pin seeking at 11 but the par three is not setup for such frivolity and their shots trickle away to leave lengthy birdie putts.
Suddenly things look tougher, the prolific birdies of earlier have turned to a trickle and Luke Donald makes bogey on 17 to slip back to -7. He will at least finish his round. Matsuyama... the birdie machine... bogey on 12. Ugly putt.

Amateur round-up
Ireland's Paul Dunne was the top performing amateur on day two, carding a 69 for the second day in a row to finish six-under, just four shots off the lead.
American Jordan Niebrugge finished four-under, France's Romain Langasque is four-under through 11, American Oliver Shniederjans two-under through 14 and England's Ashley Chesters and Paul Kinnear are both -1, just ahead of the projected cut.

D Johnson leads -10 after 11
Bogey
Johnson -10 (11), Matsuyama -6 (11)
Another miss. Another bogey. The first of the week for Dustin Johnson. It took him 29 holes but there it is. The big hitter, like Spieth, is hurt by the par three. Twice he stepped back from his putt as the wind unsettled him. Third time lucky, no way. Lips out.
And just as the three players have followed one another in carding birdies, now they complete the full house of bogeys as Hideki Matsuyama putts a bad number '4' on his card.
Bogey
Spieth -5 (11)
Do the winds bring a change?
The tee shot which left Scotland landed Jordan Spieth in too much trouble to handle and this is the ice-cool man - wearing a beanie hat - and getting very angry.
His trousers were gusting around his shins in the wind and the six-foot par putt was not good enough, back to five under.
Dustin Johnson now...
Testing moments
Johnson -11 (10), Spieth -6 (10)
Jordan Spieth has found trouble. Today has been far from smooth for him but he needs to iron out these imperfections if he is to prevent Dustin Johnson from pulling away.
Spieth's tee shot on 11 was so wide it almost landed back in Texas and he now has to get up and down on the par three. He elects to putt and the ball covers a serious amount of real estate to land around six feet shy.
Dustin Johnson is better placed, his par putt will be around four feet.
A rush to finish
Andrew Cotter
BBC Sport commentator
"When they call time for the night players do have the option of finishing the hole they are playing so there will be some mad dashing to the 18th tee for some."
Those who cannot finish must come back at 07:00 BST on Saturday.
I'm getting sick of birdies
Dustin Johnson is in for birdie on 10 and looks unstoppable. Maybe Luke Donald is the man to put up some resistance. The 37-year-old produces a firework of a putt from serious distance for another birdie.
Apologies if you think this is repetitive but the word 'birdie' is all I'm typing. Paul Lawrie... yes, birdie again. Eight under alongside Donald and Jason Day. I almost feel sorry for The Old Course. We need a bogey just to straighten things out a bit.

Woods (+6)
Tiger Woods will be going home for a long weekend. He has done that a bit too often lately. Currently at six over, this will be just the second time he misses the cut at The Open.
That's incredible!
This is ridiculous. Can someone arrest Hideki Matsuyama for crimes against reality. Just as we think his run of birdies is over he putts up and over a slope, from left to right and back down a slope for a glorious seventh birdie in 10 holes.
SEVEN IN 10. Enough is enough.
What a shot!
Driver, wedge, putter. Driver, wedge, putter. Dustin Johnson needs just three clubs in the bag.
This left for birdie on 10.
His power is stunning and this will surely be 11 under and a healthy two-stroke lead. What hole on this course can tame him?
Jordan Spieth makes par on the same hole.
I ain't afraid of no rain...

Dustin Johnson pushes his birdie attempt wide and will turn three under for his round, 10 under and leading overall.
But take a breather, absorb your surroundings, this is now looking stacked with talent. They are lining up behind him.
Jordan Spieth and Hideki Matsuyama do what Johnson couldn't on nine to move closer. Luke Donald rolls one in on 13 and is just three back while Charl Schwartzel - a major champion of the past of course - moves to eight under.
Birdie
Oosthuizen -6 (7), Day -7 (7)
Be prepared for more change at the top. Dustin Johnson, Jordan Spieth and Hideki Matsuyama have pulverised this short par-four ninth and will have very, very makeable birdie putts.

The birdie train is running through your computer/mobile/tablet, get on board.
Hideki Matsuyama - a serious hope for a major title in Japan - is making a mockery of things. This is frankly absurd. A fifth birdie in seven holes as his long putt settles in the cup.
Dustin Johnson, playing alongside Matsuyama and Spieth - boom. New leader. What about Retief Goosen on 13? You know what's coming... birdie.
Goosen now shares third on seven under with Adam Scott, Charl Schwartzel, Zach Johnson and Marc Warren.
Birdie
Spieth -6 (7)
"Don't top it into the sand, don't top it into the sand, don't top it into the sand." I think we've all faced these chips.
You won't be surprised to know Jordan Spieth didn't. Instead he nearly holed this wedge but now has a go for birdie and six under. It's downhill from 10-12 feet, minimal break, dribble... roll... drops.
Suddenly, there are birdies everywhere...

Johnson -9 (6)
Ken Brown
BBC Sport commentator
"I think I'd prefer to be Danny Willett than Dustin Johnson right now with my round completed."
Johnson goes flag hunting on seven and will have 10-12 feet for the outright lead. Not putting a foot wrong the lad.
Post update
Donald -6 (12), Day -6 (12)
"Luke Donald has played beautifully so far... until now," says Peter Alliss.
Donald leaves a birdie putt well short on 12. Jason Day on five for par... yes, he had to make that from close range though par is not really much to shout about there. Quickly back to Donald for his par... what have you got? Plenty. In she pops.

In fine touch
Johnson -9 (6)
Not a bogey in sight on Friday yet either. Has this man got what it takes?
Post update
Spieth -5 6, Johnson -9 (6), Dunne -5 (16)
The amateur of amateurs at St Andrews - Paul Dunne - has a whacky putting grip. It looks like he has a finger down either side of the grip. It doesn't get the job done on 16 as he makes bogey to drop one. A pushed putt from four feet.
Spieth for birdie on six, left to right, six feet... drained. Johnson makes par. Will Dustin be steady until the final hole on the final day. Chambers Bay all over again?
What a shot!
Spieth -4 (5), Garcia -2 (7)
Jordan Spieth, recovering from bogey on the easiest hole on the course, what has he got. Wow. Stuffs one to within a few feet on six. Massive birdie chance.
And can I have a fist pump please Sergio? Yes I can. Mr Garcia judges a putt beautifully as it drops in the front of the cup on seven for birdie and two under.

Leaderboard
One word to sum this leaderboard up? Tight.
Selected others: -6 L Donald (Eng) -5 J Rose (Eng) -4 J Spieth (US) -2 P Mickelson (US) S Garcia (Spa) L Westwood (Eng) +5 T Woods (US).
Birdie
Donald -6 (11)
Louis Oostuizen wants to play one-handed golf does he? Lashes one down the fifth but lets go of his club. Ball safe. Lucky boy. The former champion is back to four under and needs to take this par-five drag for all it's worth.
What for Luke Donald, wearing the customary visor. Not sure where I stand on a visor, I guess it prevents premature baldness from too much hat usage. He looks the part and plays the part lately. His ball settles underground and that is two under for the day and six under overall. not bad when you consider he started the round with a double bogey.
Birdie
Dunne - 6 (15)
Heard the one about the amateur who rocked up and challenged for The Open?
His name is Paul Dunne. Irish lad. Just birdied 14 and 15 to move six under. He's 22 after all. It must be those years of experience showing through.
Post update
Ken Brown
BBC Sport commentator
"A different wind direction for Jordan Spieth to deal with today and it adds a whole new dimension to this course."
Birdie
Spieth -5 (5), Johnson -9 (5)
Jordan Spieth has this monster for birdie on five...
He putts, from left to right and the ball briefly leaves the putting surface, through the fringe, it will stop short but with six feet left, that is practically a gimmee for Spieth. The kid sinks those with his eyes closed.
Dustin Johnson two putts from 30 feet or more and that will be birdie and a share of the lead with Danny Willett.
Back to Spieth, downhill... NO. Pulled it. Well I never. Check his pulse. That leaves him five adrift of the co-leaders.
Plan for tomorrow
John Murray
BBC Radio 5 live commentator
The plan is to start at 7am tomorrow and finish the second round by 10am, then begin the third round at 11am with three balls.
Ouch!
Schwartzel -6 (6)
It's sunny one moment, dark and cold the next, what the heck is going on in the sky?
Charl Schwartzel tosses one up there, does it come down with water on it or heat? It's come down alright but he may have to dig for that one, buried in some rough near the green. He looks confused. This would be an audacious up and down to escape punishment,
Eagle putts on five
Johnson -8 (4), Spieth -5 (4)
Be prepared for Dustin Johnson to tie the lead. He is on the par five fifth hole where shots get collected by players like a pub landlord collects hangovers.
Where as many players have to bludgeon their ball to reach the green, Johnson flicks one and will have a long, long put for Eagle. Now Spieth... same result. Putting from Gibraltar but an eagle attempt nonetheless.

Anyone remember the Scottish band Travis? They had a belting tune called 'Why does it always rain on me.'
The wet stuff is incoming in Fife. Think slippery, slick greens.
Birdie
Reed -3 (5), Dunne -5 (14)
"He's a streaky sort of player, when he's hot he's very hot, " says Ken Brown on Patrick Reed.
Reed, who led the US Open in its early stages in June, has three birdies in five holes to reach three under.
Ireland's Paul Dunne takes a slightly firmer grip of the silver medal which will be handed to the best amateur this week. He taps in a birdie on 14 and his nearest challenger for the honour is two further back.
That's incredible!
Matsuyama (-4 after 4)
What a start. Japan's Hideki Matsuyama has gone birdie, birdie, birdie, birdie at the start of his second round. He's now on four under and in the mood for more.

Up go the umbrellas as the rain starts to fall. It looks pretty heavy as well...
Birdie
Lawrie (-7 after 3)
Paul Lawrie is in this. The Scot won The Open at Carnoustie in 1999 and he is rolling back the years. A putt into the middle of the cup on three moves him to seven under and just two off the lead. What a fairytale this could be for the home crowd. There is something very assured about Lawrie when he is playing like this.
What a shot!
Schwartzel (-5 after 4))
Hang on a minute. This could be a big moment as Charl Schwartzel fires his second shot on the par-five fifth to within eight feet of the flag. Chance for eagle and to really shake it up among the leaders.
'All about standing on that bridge'
Faldo's last appearance at St Andrews
Faldo who finished 10-over said: "It has been a great day, and a three on the 17th has made by week.
"Yesterday was no fun and I wasn't interested in playing today but my kids told me I would regret it if I didn't play and the kids say you have to do go, you have to go.
"It was all about standing on the bridge and I wanted to bust out my old jumper. It would have been stupid to miss that. I am dying to make the cut but I am 58, I play once a year and there are kids less than half my age out there. If that is the last walk I will be really happy."
Bogey
Day (-6 after 2)
Jason Day has been in real trouble on the second after a birdie at the first. Finding the bunker off the tee, he has to produce a stunning chip and run to stone dead from off the green to rescue a bogey five. It could have been worse.
The pack are gathering
D Johnson (-7 after 3)
Another missed opportunity for Dustin Johnson. Four feet for birdie on three but he pushes it past and another par... No such problems for Luke Donald who birdies eight and moves to four under... Scores being made all over the shop now as Retief Goosen birdies nine to go to six under... Jordan Spieth sees one go by though as he pars the third and stays on five under.

Scotland's Marc Warren, who sits second on -7, on BBC Two following his second-round score of -3: "I'm delighted with that score. It was a long morning, I had just started my warm-up in the rain when the good news came in that play had been delayed.
"By the I time teed off it was just the wind to deal with, it was pretty dry by then. Obviously it was a great feeling to birdie the last hole at St Andrew's. My game is in good shape and I have hopefully put myself in contention. I will give it my best and see what happens."
Post update
Woods (+4 after 1)
Peter Alliss
BBC Sport commentator
"Tiger's got his game face on, he's not waving to the crowd in a jocular fashion. Serious stuff."
Forget about his face, he needs to get his game together. A weak putt for birdie but at least he saves par on the first. Jason Day birdies the first and is up to seven under.

The coverage will continue late on tonight though on the BBC...

Post update
Day (-6)
Jason Day, starting the day on six under, nails his approach on the first. Just a couple of feet for birdie. Great start. Tiger Woods looks to match it but can't get inside that. He isn't bad though and has a birdie chance from about six feet.
Brotherly love
They are a competitive bunch the Willetts.
After Danny took the clubhouse lead at The Open, brother Peter tweeted to remind him that he too has excelled in sport today.
Nothing like a bit of brotherly banter to bring you back down to earth.Â

Woods (+4)
From one legend to another. Tiger Woods is on the tee, looking to put yesterday's nightmare behind him. He is currently tied 127th after a four-over-par opening round. A 68 would get him into the weekend. What are you made off Tiger? No problems off the tee as he strides maningfully on.

Faldo's farewell
Faldo (+10 after 18)
It's all about Sir Nick Faldo for the moment though as he receives another ovation onto 18. About 12 feet for birdie for the three-time Open winner but there is no dream ending. He pushes it a few feet past and is left a nasty one for par.
Justin Rose for birdie from six feet... is it? No, he hangs his head in disappointment, but he will take that round. Four under for the day and five under for the Championship - well in contention.
Faldo has the last word though as he holes his clutch putt for par before raising both arms aloft. St Andrews says farewell. It has been a pleasure. (Good news for him too... he isn't last any more. Mark Calcavecchia and Ben Taylor are one behind).
Birdie
Schwartzel (-5 after 1)
Charl Schwartzel rattles in a birdie from four feet to move five under after three... Dustin Johnson settles for par on one.
Memories are made of this
Faldo (+10 after 17)
Sir Nick Faldo is making the most of his last walk down the 18th at St Andrews. He pulls on the jumper he wore back in 1987 when he won The Open at Muirfield before posing for photos and waving to the crowd. Playing partners Justin Rose and Rickie Fowler get in on the act as they put their arms around him on the bridge. Emotional stuff. "Still fits after 30 years"... says Faldo.
Birdie
Lingmerth (-5 after 9)
David Lingmerth. Remember his heroics yesterday... for the first nine at least. He went out in 29 on Thursday and he has impressed on the front nine again. He birdies nine to go two under for the day and five under for the championship. Steady scoring by the Swede.
Player reaction
Adam Scott on BBC TV: "I'm really happy with that. Any time you can have a round without bogey is pleasing. I just chipped my way round. It was not easy or hard, just a sideways wind all the way around.
"I had a big preparation the week before I played here, not wind like this but you have to chip the ball along the ground. Just thinking about (narrowly missing out on winning The Open in 2013) makes me motivated. I know the feelings and that is all great experience for me. Hopefully I will have a chance by the time I get to the last nine on Sunday."
Birdie
Faldo (+10 after 17)
Arise Sir Nick. Faldo brings the crowd to their feet on 17 with just the fifth birdie of the day on the notoriously difficult hole. He sinks an uphill putt from off the green. Brilliant. That moves Faldo to one under for the day - on what is his last Open at St Andrews - but hopes of making the cut are long, long gone. Good to see the magic is still there though.
Post update
Ken Brown
BBC Sport commentator
"The Masters champion, the US Open champion, can he become The Open champion?"
On the first
Spieth, Johnson, Matsuyama,
Here we go then. Jordan Spieth on the first as he continues his bid to become just the second man to win the first three majors of the year. He is in a decent position on five under. No nerves from the American as he lands safely on the fairway. Overnight leader Dustin Johnson has watched Danny Willett set the pace, how will he respond? A driving iron down the right. He is on seven under.
A huge roar is heard from somewhere...
Triple bogey
Kuchar (E after 17)
Just a bit more welly Phil... Mickelson misses a birdie putt by inches on the 17th. His charge has stalled as he stays on three under.
Talking about stalling, Matt Kuchar is in real trouble after a treble bogey on 17. He finds the Road Hole bunker with his first, then thins it over the road and takes three shots from there. Back to level and in danger of missing the cut.
That's incredible!
Chesters (-1) (15)
Ashley Chesters - one of the amateurs in the field - has just dropped a freakish putt across the 15th green to make birdie and return to one under par.
It's so long we can barely fit him and the hole (next to the player's head bottom left) into shot.
Ireland's Paul Dunne - another amateur - is four under, while Jordan Niebrugge of the US is on the same mark. Remember the leading amateur wins the silver medal honour.
Post update
Poulter (+2 after 1)
Ian Poulter hasn't made a great start. A five at the first before leaving his approach on the short well short of the green. A tough evening for Poults ahead?
Meanwhile Jordan Spieth and Dustin Johnson are warming up on the putting green. They tee off in about eight minutes time on five under and seven under respectively.
Post update
B. Watson (-1)
Bubba Watson pars the first and stays on one under. He needs a charge today.

Where in the pack is the steamer? Where is the player who comes from nowhere to be prominent?
David Howell at three under ahead of his 18:43 BST tee off? Sergio Garcia at two below par - just teeing off?
Rickie Fowler should be among the leaders but he has missed birdie putt after birdie putt. The Scottish Open winner has given himself so many solid chances but nothing - and I mean nothing - is threatening the hole.
Anyone fancy someone to emerge from the pack? Tweet us on #bbcgolf.
Post update
Rose -5 (16)
Birdie, birdie, birdie, birdie for Justin Rose... no, not quite. He whistles a putt from somewhere on the outskirts of Middlesbrough which goes just past. It will be par and he will have to stick on five under. Tough 17th drag next, then a phenomenal birdie chance on the last. The 2013 US Open winner is in great shape.

12 groups to go
Shaping up nicely now this. By my counting we have 36 players left to begin their rounds.
In around three hours we will begin to know if the morning hitters have done enough or will their efforts get swallowed up by some big names?
The cut by the way is currently at one under but some wise money is on that slipping back to level par.

"Within two of Danny Willett, Adam Scott is poised to strike over the weekend."
Birdie
Scott -7 (18), Walker -4 (18), Kaymer -3 (18)
The 18th hole - a drivable par four - is giving up shots like Santa gives out presents today. The three ball of Adam Scott, Martin Kaymer and Jimmy Walker all capitalise and all three are inside 10 feet for birdie.
This is Adam Scott's ball and that is a tap-in birdie and seven under.
Can Kaymer follow suit, he slides one in by the thinnest of margins. What now for Walker - lovely weight - a hat-trick of birdies.
Get Involved
England's Tyrrell Hatton tees off at 19:05 BST...
Birdie
Rose -5 (15)
Justin Rose fires an absolute worldie of an iron down the flag at 15 to leave just a few feet for birdie on a hole which has not given much up today. Indeed, it's the fourth-toughest hole on the course in round two.
Rose makes mince meat of it and can he capitalise with the birdie putt... no problems, five under par. In strong contention.
Race for silver
A solid round from Irish amateur Paul Dunne so far, with pars on the first seven holes to keep him at three under and in a shared lead for the silver medal. Tied with him currently is American Jordan Niebrugge, who has dropped two shots after his five under opening round.

Danny Daly-Arnett: Van de Velde's 18th at Carnoustie will always stick out for me. A near perfect weekend until the last regulation hole.
David Maher: Mr Liu and his straw hat finishing as runner up to Trevino at Royal Birkdale in 1971.
MNM: Seve's chip on 18th 4th Round @ St Lythams 1988 - magic chip - Mohammed London.
Bogey
Mickelson -3 (15)
Phil Mickelson is a yo-yo today. He's up he's down, his putts are in then out, make up your mind Phil and go with it. A nervy putt on 15 is badly wide and that is bogey.
That's three shots given away on this back nine. An 'oh what might have been' round is forming here.
Post update
Scott -6 (17)
It may not have escaped your attention that Adam Scott has surged the leaderboard today and did pretty well at the US Open in June too.
But have your eagle eyes picked up on the fact the man on his bag is familiar?
Steve Williams - who looked after Tiger Woods's bag from 1999 to 2011 and then moved to work with Scott - was no longer in the caddying game and until recently, lived a rural lifestyle in his native New Zealand.
"Steve was adamant that he was not going to caddie in 2015, so he took some convincing, but I am very happy he's agreed to help out," Scott said.
The pair will be working together for the majors and it seems to be doing the business.
Post update
Scott -6 (17)
Mark James
Former Ryder Cup captain on BBC TV
"Adam Scott looks back to his best in America. He could be a real contender this week."
Birdie
Rose -4 (14)
If you are just joining us, the horrid 17th hole is playing slightly - and I do mean slightly - easier today. It is now home to Adam Scott, currently six under, and he needs to find the right of the fairway to be best placed. Nails it with driver and could not have placed it better.
What about Justin Rose? He is going about his business doggedly and has been all day. The 34-year-old pounces on a par five to make birdie. That is birdie on 13 and 14 for him and four under overall.
'Length and fluidity'
Peter Alliss
BBC Sport commentator
"The cameras are gathering around the first and why not? One of the great, great champions is Tom Watson, who has won this Championship five times, is there. Members gather in the window to watch the old boy drive off, maybe for the last time.
"Watch the swing when he drives, the length, the fluidity of it and marvel at the fellow. It won't be long before he gets his bus pass - but it is truly remarkable how easy he makes it look."
Post update
Watson (+4)
The last time we see Tom Watson on the tee at The Open? Possibly. Although at +4, he will hope he has at least two more rounds left in him after this... Safely off the first.
Redknapp on Watson
Watson (+4)
Former Tottenham manager Harry Redknapp has paid tribute to five-time Open winner Tom Watson ahead of the second round.
"Tom Watson is a fantastic sportsman and it will be emotional to see him walk over the Swilcan Bridge for the last time," writes Redknapp. "I saw him win The Open at Troon and even when he was in the heat of battle he made sure he smiled at the spectators and took time to acknowledge them. He's a true gentleman and a fantastic golfer and I thought it was a real shame he got some stick after last year's Ryder Cup, he didn't deserve that."
A final farewell?
Watson (+4)
A forty year love affair with the Open Golf Championship is coming to an end - possibly.
Tom Watson first played in the Open in 1975, won it five times and remarkably came close to a sixth as a 60-year-old in 2009.
This week he teed off for the final time - we expect - and what better place to do it than at St Andrews - recognised the world over as the home of golf.
So the BBC's Alex South thought he'd fire in a quick round of his own with Watson. Watch here.
Watson tees off
A five-time winner and on his 38th Open outing, here comes Tom Watson.
Will this be his last opening tee shot at a competition which where he will forever be fondly remembered?
Birdie
Stenson -1 (14), Mickelson -4 (14)
Henrik Stenson makes par on the par five 14th, a wasted put gets pushed past. Much like Rickie Fowler today his work is good until he gets within 10 feet of the cup. Phil Mickelson can only make par after using his bucket and spade from the bunker but this lot can wait for a while, we are probably about to see the final opening tee shot from a legend in the Open...
Post update
Johnson (-7) tee time 17:48 BST
Peter Alliss
BBC Sport commentator
"You can almost smell the rubber burning when he hits a driver."
Overnight leader Dustin Johnson is on the range but he still has some time to wait, not teeing off until 17:48 BST due to the rain delay earlier today. He will be chomping at the bit...
Stat attack
No doubt the opening nine proved easier yesterday. Will the afternoon guys get a tough few hours as they did yesterday?
Post update
Peter Alliss
BBC Sport commentator
"The scoring has been excellent when you think of the weather predictions and the way things looked at 7:00 BST. There's been some wonderful scoring. I thought the qualifying score would be well over par. But still, a long way to travel. It has been remarkably good."
Bogey
Goosen -5 (1)
What is this? Retief Goosen follows Luke Donald up the first and it is dismal stuff. A bogey, not quite as bad as Donald but maybe a precursor? Conditions stiffening?
Ouch!
Mickelson -4 through 13
Anyone else get nervous when a pro takes driver off the fairway? It's such a risk-reward play and Phil Mickelson will wish he hadn't bothered when he walks up the 14th fairway. After an almighty whack, his ball runs and runs into a sand trap near the green. You are all wise enough to know that bunkers here are around 10,000 feet below sea level.
Double bogey
Donald -2 (1)
Poor old Luke Donald, such a friendly face. He probably felt elated waking up this morning at four under going into round two. There's nothing like a double bogey on the first hole to deliver a hard right hook into the rib cage. Pick yourself up and dust yourself down Luke, go again.
Jimmy Walker of the US has caught a bit of the Donald shakes, missing a similar short putt for par on 15. Walker will slip to three under. Walker is some player, only Jordan Spieth above him in the PGA Tour's Fedex Cup rankings.
Player reaction
Willett clubhouse leader on -9
"It is pretty cool to be leading The Open, it is what you dream of. I have grown up watching the event and for us Brits it the major we want to win, especially here at the home of golf makes it a little bit more special.
"I could be leading going into tomorrow, I am not sure what the weather is doing but the others won't be finished until tomorrow. I will rest up and see if I can have a good weekend."
Birdie
Mickelson -4 through 13
If you are just joining us Phil Mickelson carded a double bogey on the 11th hole which ruined some super early work but he is back on kilter, sinking this little tester on 13 to make birdie and four under.
Player reaction
Johnson content wit seven under
Zach Johnson speaking on BBC Two after finishing on seven under: "I had a couple of three putts but all in all I am pretty happy. Great rhythm, play athletic and hit your shot. There is a lot to be said about that."
A lot to be said for his round indeed. Johnson has already won a major remember - the Masters in 2007.
The ultimate barometer
American golf writer Doug Ferguson...
Birdies
Kaymer (-2), Streb (-7), Ogilvy (-5)
The projected cut is around level par at the moment but may slip back as conditions get tougher. Germany's Martin Kaymer is well inside the line as he makes birdie on 14 to move two under.
What is this on second? Robert Streb of the US is into a share of second place as he sinks a bomb from 20-30 feet.
And this birdie train is unstoppable, Geoff Ogilvy at the wheel on 18. "All aboard, all aboard", five under for the Australian.
Gusts and gusts
Ben Dirs
BBC Sport at St Andrews
"A weather forecast from the course: Chance of a few showers, especially later, but they should tend to move through quite quickly on the wind. Wind increasing to 20mph, gusting to 30mph later.
"Saturday: Very windy. Chance of showers to start the afternoon but becoming drier and brighter with increasing amounts of sunshine through the afternoon and into the evening. Winds 20-25mph with gusts 30-40mph. Gusts should start to ease into the evening."
What's the weather doing?
Some weather news next which may please Danny Willett...
It's been a long wait
There has not been an English Open winner since Nick Faldo in 1992... No pressure then Danny Willett...
Birdie
Willett leads on nine under
This could be a key moment for Danny Willett on 18. After a couple of dropped strokes late in this round he has this 10 footer for nine under and a two-stroke lead. All in black, he stands over it, sets it on its way... never in doubt. A crisp putt and an Englishman leads The Open Championship.
His 69 was rock solid. A minor wobble but not even Harry Houdini could escape this course unscathed.
The hardest hole
Things are proving a little easier today on 17 though as Thongchai Jaidee and Geoff Ogilvy nail putts from distance for the third and fourth birdies of the day on that hole. Better than the big fat zero from yesterday.
That's ugly!
