The fat lady is not yet singing, this tournament is not yet over but this live text is.
Thank you for a dozen hours of company, hundreds and hundreds of tweets. Please come back tomorrow at around 14:00 BST but check the tee times when they are published and we will be live for the start of play.
Those tee times will be on our website when they are published so keep an eye out.
For now, good night. Try not to have any nightmares about the 11th hole.
His second day's play was exemplary, headline grabbing and pretty flawless. It's made more impressive as it follows a day where he was exactly the same.
But let's be honest, Augusta is the grandest golfing stage, built for drama and what is more dramatic than a comeback...
And so we go on to what is known as 'moving day'. The round where the pack shuffles and people make a charge. Unless Paul Daniels is shuffling, Jordan Spieth will surely still be top of the deck come Sunday morning...

Jordan Spieth may be threatening our weekend enjoyment as he decimates this course but one man who will be overjoyed at how this tournament is going is Mark O'Meara on four under.
The 1998 Masters and Open champion made the cut for the first time since 2005.
Ernie Els is nine back. If you're reading Ernie, relax, you've got two rounds and Jack Burke only needed one...
Former Open champion Darren Clarke said he was happy to make the cut at the Masters following a second-round 71 at Augusta on Friday that left him one over at the halfway stage.
"I made a couple of silly mistakes but those things happen,"said Europe's Ryder Cup captain.
"I don't know what golf course Jordan Spieth is playing but it is not the same one I am playing. Just wow."
Where can you lose this Masters?
The 11th hole is a place of trouble for many. This is the long par four drag where many opt to play their second shot right of the green, thus avoiding water trouble.
It is the hardest hole on the course over two days, giving up just six birdies. It takes an average 4.46 strokes and has claimed 56 double bogeys.
Justin Rose, who shot a two under 70 and is seven under for the tournament: "I was not really enjoying myself in the first two holes. It was a tricky start but I just tried to remember a couple of other rounds here and I think it was in 2007 when I got off to a poor start in the final round and went on a run so I was just trying to create momentum. I had to just forget what had happened and remember yesterday's performance.
"You can't press it too hard on this course you have to let your birdies come and take your opportunities when they come."
Charley Hoffman speaking to BBC Sport: "I drove it a lot better, gave myself opportunities, missed a couple coming in but really happy with how I played.
"We've only played 36 and we've got 36 more so there's a lot of golf to go. You can make a lot of birdies out there and hopefully I'm there coming down the back nine on Sunday."
The 2001 Open champion and twice Masters runner-up David Duval seems very much of a mind this tournament is now a two-horse race.
"Heck of a battle going on for third right now,"he tweets. "If Jordan posts 143/144 for the weekend can anyone other than Hoffman catch up? The biggest battle moving forward this weekend for Jordan will be in his own mind. Got to stay present."
BBC Sport commentator at Augusta
"He has possibly played the best 36 holes in a Major championship ever.
"Today particularly there was more wind about and the pins were tougher. To shoot 130 over 36 holes excellent, almost more so because he is 21.
"Total quality. His putting has been of the highest quality."
Wow. Reflection time. A marathon day with one man just streaking clear, oblivious to the pack. Is this the tournament where Jordan Spieth becomes a household name to those perhaps not golf mad?
Is he getting worse though as the week goes on? The 21-year-old found 13 greens from 18 today, two fewer than yesterday. His driving also tailed off as he landed nine of 14 fairways rather than the 11 of Thursday.
World number one Rory McIlroy: "I find myself 12 back and I needed to have a good back nine to be here. I have been able to salvage something from the day which is the only good thing I can take from it.
"I hope I can find another gear. It's hard to know when it is going to come. Jordan obviously has it this week. It is going to take two phenomenal rounds for me and some average rounds for some other guys in the field for it to happen."
South African Els, who is nine shots behind Spieth, said: "Jordan is playing unbelievably well and obviously we're all watching the leaderboard. But we know how far there is to go.
"Front runners tend to do well here, but there have been some really good comebacks, so it's a big weekend ahead."
The two-time Open champion added: "I'd really like to shoot two 67s and see where that leaves me.
"If it keeps blowing like this and the nerves get going... I don't want to wish badly on anyone but if he takes his foot off the gas or has a bad break here and there, it really gives you thought of catching him."
Paul Casey is seven under and has been speaking to BBC Sport: "I've holed out extremely well over the two days, the key to keeping me in contention, though I'm not sure seven back is.
"If you told me the beginning of the week seven under would be seven back I wouldn't have believed you. I never though this course would yield 14 under. That's phenomenal golfing. Really it's a two horse race as it looks right now. They keep ploughing ahead like that we are playing for third or fourth."
Well, it looks like it's Jordan Spieth's Masters - the 21-year-old from Dallas is five clear of the field and playing some special golf. However, the leaderboard is looking far more interesting than it did a couple of hours ago and if Spieth goes level par on Saturday and a couple below him fire rounds in the mid-60s, it's all on again.
Tom Watson: Rough day, I tried to hit the driver too hard...too many pull hooks. This and some poor putting and I am not playing the weekend. Next Year!
Watson finished nine over on day two and eight over overall to miss the cut.Ian Poulter: This game is certainly won and lost on the putting green. Obviously I need to work harder. No excuses just plane old grit & determination.
Level par for the day, Poulter is one over overall.
Only three men still out on the course, Holmes, Snedeker and Kaymer. Twenty-eight players under par, the cut line is two over. Players to miss out on the weekend include England's Luke Donald, Ireland's Padraig Harrington, Frenchman Victor Dubuisson, Germany's Martin Kaymer and former champion Trevor Immelman.

"Can McIlroy come from 12 back? He could but I don't think he will because of the guy who is out in front. Let's not forget, this guy won once and came second twice coming into this tournament."
Former American professional golfer on BBC Radio 5 live
"Professional golfers in general have a pet peeve. If you make a bogey and make a birdie, you don't get it back. The bogey still stands. McIlroy played himself into a better position than he was, but the 40 opening nine still stands.
"I'm going to throw something out there. In 1997, Tiger Woods shot a 40 on one nine when he won."
BBC golf correspondent on Radio 5 live
"He looked finished at the halfway stage in this round, now he has clawed himself back."
Mickelson has got plenty of work to do to make par at the last, slippery long-ranger down the hill... beautiful, just a feather, finishes a couple of feet left. McIlroy for birdie and a round of 71 - he's 12 behind but it could have been a whole lot worse, having gone out in 40. Moore makes his four-footer for a six-under 66, joint lowest of the day, and four under overall. Mickelson is six under after a 68, eight off the lead but still in it.
Lizzy Dixon: My ex-boyfriend introduced me to golf last year. Now, I'm listening to it on my own and loving it. Poor Rory.
Up at 18, Schwartzel squirts his downhill par putt past the hole, he'll card a 70 for three under overall. Mickelson with his second into 18, starting it out left and hitting it too far, his ball refusing to come back down the slope. McIlroy all over the pin with his approach, could be another birdie.
Two-time Masters winner Ben Crenshaw, after playing his final tournament at Augusta, says on Sky Sports: "It [Augusta] has meant everything to me. There is no place like it and I am just thrilled I won two Masters and have been in a fight for a lot of them. People treat their champions here unbelievably. They make you feel welcome and I will never forget this day for the rest of my life.
"It was so wonderful to see Carl Jackson (who has caddied for Ben Crenshaw 39 times at Augusta). He has had a health setback but he looks OK, he just needs to take it easy. Yesterday was a very humid day and it would have been tough on anyone. It was great to see his tall figure when I came off the green, I could not have done many things without him. He is a wonderful man and a wonderful friend."
We have had talk of potential rain all day. What impact would a downpour have for tomorrow? Probably little with so much time before the players go again. Hunter Mahanwants the water to avoid the course.
McIlroy has chipped in at 17 - birdie, he's back into the red. Moore, too, rolls in his birdie, that's his third in a row and he's now four under. Mickelson, not to be outdone, also makes birdie, he's now six under and outright sixth.
Ryan Moore into the 17th, his irons have been hot today. Mickelson has somehow flown his ball over a pine tree about six feet in front of him and parachuted in to within about six feet of the pin. No idea how he did that, but I'd sell my gran to know.
Earlier we asked for you to vote on whether you think Jordan Spieth can be caught at The Masters and 57.7% of you say yes he can.
Ryan Moore - apologies, I mixed him up with Palmer a moment ago - birdies 16 and is five under for his round and three under for the week. Casey's birdie putt at the last just misses - the Englishman cards a 68 for seven under and a tie for third. No bogeys today for Casey, and only one in the first two rounds. If you'd told him he'd do that beforehand, he might have thought he'd be leading.

"The players are taking no time with their shots at all, they want to get it done because there is weather in the air. There are really dark, fearsome clouds gathering."
McIlroy putting from the fringe and his birdie attempt breaks too soon. Taps in for par, stays level, 14 off the lead - he'll be here this weekend but his challenge is over. England's Danny Willett has made the cut - two 71s on his Masters debut, that's some golf from the Sheffield man.
Mickelson with seven or eight iron off the tee at 16, that's not much cop. Ryan Moore very nearly sticks his tee shot in, McIlroy is right over the pin. Mickelson comes up well short with his second - greens playing slow this week - and he's got a lot of work to do to save par.
Mickelson makes that birdie, he's now five under and tied for sixth with Ernie Els. That's always what's nice about a Masters leaderboard, the mixture of old and new and greats of the past, present and future.
Four-time Masters winner Woods pointed to Australia's Greg Norman's collapse in 1996 when he lost a six-shot lead to England's Nick Faldo on the final day.
Woods said: "I'm still right there. I'm 12 back, but there's not a lot of guys ahead of me. And with 36 holes here to go, anything can happen. 1996 proved that.
"So we have a long way to go. There's so many holes to play and so many different things can happen. We don't know what the conditions are going to be"
