  1. Goodnight and farewell

    As Mansour Bahrami and Henri Leconte amuse the Centre Court crowd with their clowning doubles antics, we are heading for home.

    But in the meantime there are still plenty of live tennis matches taking place - go to the live tab and take your pick from our video selection.

    And remember there's Wimbledon 2day starting at 20:00 BST, rounding up all of today's matches.

    The live text will rev back into life tomorrow morning to bring you all the build-up and then coverage of the day's action.

    See you there.

  2. Post update

    Tomorrow then.

    Andy Murray is first on Centre Court against Vasek Pospisil, followed by Novak Djokovic against Marin Cilic.

    Over on Court One, it is Gilles Simon v Roger Federer and then Stan Wawrinka v Richard Gasquet.

    Lovely jubbly.

  3. One of my toughest matches - Anderson

    Kevin Anderson has gathered the strength to tweet after his crushing defeat by Novak Djokovic. 

  4. Nobody puts Drake in the background

    Singer Ciara

    US singer Ciara was at Centre Court today apparently.

    I have no idea who she is.

    But that mirrored aviator sunglasses disguise is a big giveaway that she is someone worth getting a snap with and then googling later.

    When will these celebrities learn?

  5. More injury problems for Raonic

    Milos Raonic missed the French Open after having foot surgery, returned for Wimbledon but is still not fully fit. 

    Raonic, beaten in round three at SW19 by Nick Kyrgios, will miss Canada's Davis Cup tie against Belgium next week.

    Tennis

    So this is your semi-final line-up. Reckon, you can pick a winner out of that little lot?

    Yeah, so do I. But Williams' generous scheme of giving away sets means there is a punchers' chance for the other three.

    Serena Williams: "It was really fun out there. I was smiling at one point and I saw Victoria smiling as well. We both really enjoyed it. It's been up and down, up and down but somehow I'm still alive. I'm just happy to be here."

    Asked about her semi-final opponent Maria Sharapova, she says: "It's been a while but she's been playing really well, she's such a fighter. I look forward to it. I don't have anything to lose, I'm just going in there trying to win a match."

    The interviewer mentions the Serena Slam, but Serena wiggles her finger and politely says "no Slam" talk today.

  11. Post update

    Serena says that it the match against Victoria Azarenka was "tremendous fun" and a "great atmosphere". I don't think she would have said the same after her last two matches against sister Venus or home crowd favourite Heather Watson.

    "Somehow I am still alive, so we will have to see what is next," she concludes.

    Full quotes to come.

    Serena Williams

    "A huge celebration there from Serena. An incredibly high quality match, everyone was up on their feet at the conclusion of a match that was by far the best of the tournament. It's great to see Victoria back playing at this level as it's been a while. Serena is two matches away from another grand slam."

  14. Game, set and match

    Williams 3-6 6-2 6-3 Azarenka

    Serena Williams

    Serena Williams steams on towards her full house of Grand Slams.

    But the hug for Victoria Azarenka and standing ovation are fully deserved.

    That was a tremendous match and Azarenka brought the best out of Serena.

  15. Break point saved

    *Williams 3-6 6-2 5-3 Azarenka

    Serena Williams nets a simple forehand for 30-40. Break point for Azarenka.

    What does Serena do? She pulls an ace out of the quiver of course.

    Deuce.

  16. Post update

    *Williams 3-6 6-2 5-3 Azarenka

    Two aces follow. The second a 113mph rocket onto the line. Her 16th of the match. 30-30. Two points away...

  17. Post update

    *Williams 3-6 6-2 5-3 Azarenka

    Gutsy from Victoria Azarenka. A forehand winner up onto the baseline following a double fault gives her 0-30 and a lifeline...

  18. Azarenka holds

    *Williams 3-6 6-2 5-3 Azarenka

    Victoria Azarenka keeps herself alive in the match, in the championship with an arcing ace out wide.

    Williams to serve for a place in the last four though next.

    And she has a set of shiny new balls to do it with.

  19. Deuce on Azarenka serve

    Williams 3-6 6-2 5-2 Azarenka*

    Victoria Azarenka is hunched over, fist clenched, teeth gritted with every point she manages to prise from Serena Williams.

    A double fault at 40-15 - as she tries to smuggle the second serve past the American - has her back under the pump though.

    Another missed first serve.

    Serena slugs away a lovely forehand winner down a sliver of court to take us to deuce.

    Azarenka to serve to stay in the match...

  21. Post update

    Williams 3-6 6-2 5-2 Azarenka*

    Never mind Azarenka, give me a chance Serena.

    Three aces on a row, with barely a bounce of the ball separating them take her flying to 40-0.

    Azarenka managed to claw a return back on the fourth point of the game, but that is the only chance to feel fuzz on string for her.

    Serena hammers away from midcourt for a hold to love that weighs in at a puny one minute 15 seconds.

  22. Post update

    *Williams 3-6 6-2 4-2 Azarenka

    Azarenka

    Serena Williams is still hunting Victoria Azarenka's runt of second serve, but she has come out of that game empty-handed.

    Azarenka has kept hitting out in the rallies, kept Williams moving and kept her side of the scoreboard ticking.

    Serena Williams

    Serena Williams have been rummaging and clunking around the gearbox. There have been a few stalls and back-fires.

    But now she has slipped into top transmission slot.

    Her game is roaring on all cylinders, whisking that service game from beneath Azarenka to love in just over a minute.

  25. Azarenka holds

    *Williams 3-6 6-2 3-1 Azarenka

    This match needed that.

    Victoria Azarenka hangs on to her serve to stay within a break's reach of Williams.

    The Belarussian grips her fist and lets rip with a squeal of delight and determination.

  26. Break point saved by Azarenka

    Williams 3-6 6-2 3-0 Azarenka*

    This is Serena in cartoon superhero mode.

    Zap! The top seed boshes away a backhand down the line. Blammo! A forehand zips away for a winner with Azarenka dragging her feet behind.

    30-40 and break point. Saved as Azarenka finds some of that muscle to plonk down a rocket serve.

    Not out of the woods yet. Into deuce indeed.

  27. Post update

    Jana Novotna

    Former Wimbledon champion on BBC Radio 5 live

    "You get a sense by seeing Azarenka's body language that she is going through the emotions. She looks a touch tired with challenging Serena from back of the court. Something is creeping into her mind."

    "Victoria will have to do something very special to turn the momentum around."

  28. Post update

    Williams 3-6 6-2 3-0 Azarenka*

    Serena Williams has just produced one of the shots of the tournament so far.

    Victoria Azarenka's attempted pass could not have been better - clearing the tape by a pimple and loaded with top-spin - but Serena gets down low and volleys off her bootlaces with a wrist of iron.

    The ball floats over perfectly to leave Azarenka stranded at the back.

    Delicious. Forty-love. The game soon follows. Williams on the charge, the last four on the horizon.

  29. Game, set and match Radwanska

    *Keys 6-7 (3-7) 6-3 3-6 Radwanska

    Radwanska

    Brains overcomes brawn. Keys wild on the forehand - two match points Radwanska. The Pole can't secure victory at the first opportunity, but on her second chance she forces Keys onto her heels and beats her stranded opponent with a straightforward forehand. The 2012 Wimbledon finalist is into the last four.

  30. Post update

    Keys 6-7 (3-7) 6-3 3-5 Radwanska*

    Radwanska with a surgeon's touch around the court - a lob sends Keys scrambling and she follows up with a sweetly-struck dropper which brings up two break points. The young American holds firm, thwacking an ill-judged Radwanska lob. But it's a temporary reprieve for Keys, despite Lindsey Davenport bellowing from the sidelines. Radwanska within a game of the semi-finals.

  31. Williams breaks

    *Williams 3-6 6-2 2-0 Azarenka

    Serena Williams

    Victoria Azarenka is at Serena Williams' mercy whenever she misses with her first serve.

    The underdog gets off the hook as Williams piles into a return at 15-30 and goes wide.

    But it is only a partial reprieve.

    Williams arrows away a forehand winner for 30-40 and then lures Azarenka long to move a break up.

    It will be difficult to rein her in from here.

  32. Post update

    Williams 3-6 6-2 1-0 Azarenka*

    Leon Smith

    GB Davis Cup captain on BBC Radio 5 live

    "So good to watch this match, a privilege to watch. Azarenka was dominating the first set with her serve, perhaps it dipped a bit in the second and Serena get on top of the second serve and dominated play. If Azarenka can lift her serve then she has great chance but Serena looks like she is out to get a win."

  33. Post update

    Williams 3-6 6-2 1-0 Azarenka*

    Venus Williams watches sister Serena on Centre Court

    Happy days for Venus Williams. Her sister Serena has the momentum now, taking the opening game of the third set to 15 with her ninth ace of the match sealing the final point.

    I'm not sure how the older Williams sister would have fared against Victoria Azarenka today.

    The Belarusian - currently 24th in the world - will be back up towards the top five very soon on this evidence.

  35. Post update

    *Keys 6-7 (3-7) 6-3 3-4 Radwanska

    There's no way of knowing which way this match will swing. 30-30 - Keys screws a backhand into the tramlines. The Pole, though, isn't able to inflict that killer blow.

    The pair swish and sway between deuce and advantage before Radwanska produces a super winning forehand, and the game reaches its conclusion when Keys goes long. It's still with serve.

    Former Wimbledon champion on BBC Radio 5 live

    Azarenka

    "You can feel that the momentum is changing in the match. Looking at Azarenka's face you can see that something is missing, she is thinking.

    "We are in for a treat. From the very first point it has been an exciting match, especially after Serena played a subdued match against her sister Venus in the previous round, we now have two players giving their utmost. A treat to be here and enjoying this match."

  38. Game and second set

    Williams 3-6 6-2 Azarenka

    Serena

    Serena Williams is back in the room.

    Victoria Azarenka won only 33% of points on her second serve in that second set. When you are only landing with 60% of your first serves, that leaves you with a lot of ground to make up.

  39. Deuce on Azarenka serve

    Williams 3-6 5-2 Azarenka*

    Victoria Azarenka dribbles a volley wide, sticking her tongue out in exasperation as she looks up at 15-30 on the scoreboard. Two big old first serves take her to the brink, but Williams tucks into a second serve like a seafood platter to take us to deuce.

    Where is the mojo hiding in this match? Anyone's to win at the moment..

  41. Serena holds

    Williams 3-6 5-2 Azarenka*

    Serena Williams

    Serena Williams is off the slab and running.

    Victoria Azarenka strays into the net for 30-40 before her attempted lob is hooked out of the stratosphere by a back-pedalling Williams to take us to deuce.

    Williams completes her escape with a bellow of delight. This match is following the classic Serena template - it takes a whole world of trouble to bring the best out of her.

  42. Break points against Williams

    *Williams 3-6 4-2 Azarenka

    Serena Williams coughs up a double fault to give Victoria Azarenka a leg-up to 15-30.

    Brilliant defence from Azarenka, guessing right like a shoot-out goalkeeper to pat the ball back and force another shot from Williams. Into the net!

    15-40 and two break points.

  44. Williams breaks

    Serena Williams

    Laser guided-depth and angles measured with protractor accuracy from both players.

    This really is vintage stuff.

    Break point Williams, Azarenka into the net, the pass attempt is a whisker wide.

    Take two. Another break point for Williams, Azarenka presses forward again and this time she reels in the break as Azarenka fails to get a dipping backhand up off her toes.

    Opera singer Katherine Jenkins

    Katherine Jenkins' face has been stunned static by the sight of that tartan suit behind her as she takes her seat.

    Serena Williams is far more animated. The top seed points accusingly at the court surface, believing that a dodgy bounce is behind the framed forehand that allows Victoria Azarenka to 40-15.

    Williams is chiselling away though and has worked her way back to deuce... Maybe a chance here.

    Keys 6-7 (3-7) 6-3 Radwanska*

    Keys

    At 30-30 the game could swing either way, but Keys cannons a forehand winner into the corner to bring up a set point. Set point? Means nothing. Keys beyond the baseline. Deuce. But she engineers a second break point and ruthlessly wins it with an ace down the T.

  52. Post update

    Williams 3-6 3-2 Azarenka*

    Serena Williams folds in the middle after getting her footwork all wrong on a backhand and duffing a clumsy shot long for 30-40.

    Break point Azarenka. And a second serve to look at. Saved with some old-school serve-volley fun and games.

    Serena makes her way to safety, but her hopes of a full house of Grand Slam titles are in danger.

  53. Keys breaks

    *Keys 6-7 (3-7) 5-3 Radwanska

    Break point Madison Keys and the big-hitting American secures it with a fortunate net cord. She raises her arm, apologising for her good fortune but, undoubtedly, she's glad to have the opportunity to serve out the set.

    Jonathan Jurejko

    BBC Sport at Wimbledon

    While neither Serena Williams nor Victoria Azarenka would trouble the ear-splitting shrieking of Maria Sharapova on the decibel meter, this pair are certainly creating plenty of noise on Centre Court.

    Azarenka's wailing 'hhherrrrs' are being met by Williams' lower-pitched 'ah-haaas', which almost sound like the American is guffawing during these long rallies.

    And that makes many in the Centre Court laugh during some points, prompting the umpire to remind fans that they should remain silent. Ssssh!

  55. Azarenka holds

    *Williams 3-6 2-2 Azarenka

    A gritty hold, but there were warning signs for Azarenka.

    Her serve is being put through the mincer every time by Serena Williams.

    One crunching return from Williams knocks her back from advantage, before the American again tries to swat a clean winner, but is just millimetres wide.

    Radwanska has one particularly enthusiastic supporter on Court One. The Pole peppering the court with delicate shots - drops shot, lob. They don't always work, but it's pleasant to watch. Both players holding serve comfortably but won't do so forever.

  58. Two break points saved by Azarenka

    Williams 3-6 2-1 Azarenka*

    Serena Williams

    Serena Williams forces a break point for the first time since the opening game of the match.

    Victoria Azarenka is stretched thin across the back of the court as she is forced into shuttling defence. She fully earns her passage back to deuce as Serena pumps long.

    A second serve gets the full treatment next though, thumped away for a second break point.

    More tremendous rearguard hitting from deep from Azarenka hustles Williams out of it again.

    Azarenka is clinging on. Just.

  59. Deuce on Azarenka serve

    Williams 3-6 2-1 Azarenka*

    The quality of this tennis is final-weekend stuff not the start of the second week.

    Former world number one Victoria Azarenka beats current top dog Serena Williams with a backhand full of placement and precision.

    Serena Williams comes to the net to gleefully swat away a running volley for 15-30. Victoria Azarenka with a sublime drop volley onto the tramline for 40-30 and then lifts a forehand just wide with Williams out of court to take us to deuce.

    Cracking stuff, a pleasure to watch.

    Williams

    Victoria Azarenka climbs into a mid-court bounce, flinging the kitchen sink, the white goods and the rubber gloves, into a forehand winner for 30-30.

    That seems to awake Serena Williams from her slumber though. A delicious stretching cross-court backhand from out wide lands for a winner and is greeted by a scream of delight.

    This is brewing up into something special. Hold on to your sweatbands.

  62. Post update

    *Williams 3-6 1-1 Azarenka

    Azarenka

    Victoria Azarenka's serve is a right old pick-and-mix.

    Her fourth double fault of the match is followed by her fourth ace for 40-15. But when the rallies break out, she is more than holding her own.

    She is not quite bullying Serena off court, but the top seed has not caught fire just yet and seems a little disconcerted by the power that Azarenka is generating off the deck.

    Williams 3-6 1-0 Azarenka*

    Serena Williams

    Losing a set on her way to victory is just what Williams does in Grand Slams this summer. You can't write her off yet.

    But if she does fail to make the last four, then the semi-finals will be filled by seeds 23, 4 and either 21 or 13. Pretty open.

    Let's not get into those games just yet though. Williams opens up the second with a hold to love that contained three aces and was bristling with intent.

  65. Game and first set Radwanska

    Keys 6-7 (3-7) Radwanska

    The first set has just been won on Court One too.

    Madison Keys is soon back in trouble in the tie-break, trailing 2-6, and this time her forehand is largely to blame. Radwanska sees another set-point come and go before Keys plays another sloppy forehand, giving the advantage to the 2012 runner-up from Krakow.

  66. Game and first set

    *Williams 3-6 Azarenka

    Azarenka

    A twitchy tentative double fault from Victoria Azarenka puts her in a bit of bother at 30-30, but she does tremendously to shift Williams off balance with a naughty backhand angle for 40-30.

    Williams coming up short of a length, Azarenka advancing, and away goes the forehand winner, slid down the line for a winner and the first set.

    Tracy Austin

    Two-time US Open champion on BBC TV

    "I think it (the debate over shrieking in the women's game) might be done as I'm not sure there is much they can do about it. It all began with Monica Seles and there was a lot made of it. Sharapova and, in particular, Azarenka, have said they are not going to change."

  68. Post update

    Williams 3-5 Azarenka*

    Williams saves the first set point with a ram-jammer of a serve and then bruises her way through the next, tip-toeing around the very edge of the lines, to move to deuce.

    Azarenka can't get the job done on the Williams serve. But that would have been a bonus.

    Now, she has the chance to nail it tight shut on her own serve.

    "The power of the ground strokes is exceptional as is the big serves. The second serve speed is also high. This match is about Serena, she is the favourite. She is hitting the ball so well but I am also impressed with how Azarenka has matched Serena's power. Not many can.

    "The confidence with which Azarenka is playing is very encouraging. Not getting overwhelmed and really going after the ball."

    Probably not. I wouldn't blame you for erasing all traces from the memory banks.

    Anyway his 21st century equivalent Drake is here, hugging it out with Venus Williams before taking his seat.

    No immediate break-back joy for Camp Williams. Azarenka still impressing as she moves further ahead on the scoreboard with a hold to 15, crowned with an ace.

    Victoria Azarenka holds her backhand stroke at the top of the backswing like a kind of threat, before hammering Serena Williams back behind the baseline for 15-30.

    Serena

    Both players are absolutely clubbing the ball from the back of the court. Fred Flintsone-style tennis with great, big bruising groundstrokes.

    It is engrossing stuff. Serena Williams smacks a fizzing forehand return winner to apply a bit of pressure at 40-30.

    In comes Victoria Azarenka on the next point, putting a volley beyond the reasonable reach of Serena Williams.

    Nothing shy or retiring about that opening rally.

    Both players thumping the ball like a punchbag from the baseline.

    Williams loads up on a return on the next point, but her forehand sprays wide. 30-0.

    Un-oh. Azarenka service action is suddenly spluttering and smoking. Two double faults offer up a break point at 30-40. Saved with a big serve out wide. It took some grit to dig that serve out of the locker.

    To deuce.

    So let's see what the history book has to tell us.

    Well, it is a Steven King-style nightmare-generator for Victoria Azarenka.

    She has lost 16 of her 19 meetings with Williams including the last four and their two at Wimbledon.

    The silver lining for Azarenka? The Belarusian has three match points in her meeting with Serena Williams at Madrid earlier this year, but could not see it out.

    Williams v Azarenka

    Centre Court has pretty much cleared out. Time to empty bladders and recharge glasses.

    It means that five-time champion Serena Williams and Victoria Azarenka - chunky earphones clamped over her lugholes - emerge to little more than a ripple of applause.

    Williams coach Patrick Mouratoglou and her surprisingly-hard-to-spell hitting partner Robbye Poole are in place in her box, long with mother Oracene.

    Sharapova turning her back on Vandeweghe after every point, trying to find a Zen-like calm at the back of the baseline.

    Vandeweghe behind then, but she was behind in the second set. The American nips ahead to 30-15... Sharapova looping a forehand long. Two break points Vandeweghe. A booming serve comes to her rescue and then a Vandeweghe forehand drifts long.

    Vandeweghe pouncing on anything that's a fraction short, which is why Sharapova drags a backhand into the tramlines. Third break point. Sharapova crumbles! Into the net! Vandeweghe waves her arms in the air, encouraging the crowd to cheer her on. We're back on serve.

    There is something of the Wild West gunslinger about Coco Vandeweghe. She has been out-gunned here though.

    She ambles about at the back of the court, collecting service bullets off the ball boys before swaggering to the baseline and firing down some meaty serves.

    A lovely loose-limbed forehand brings up 30-0. But Sharapova bites back, a lucky net cord followed by a delicate scooped lob into acres of open court. 30-30.

    A pinging rally. Sinews stretched, strings straining, finally Coco wallops a bounce smash from back near the baseline into the net. 30-40 and break point.

    Saved, but here comes another.

    The Vandeweghe backhand is the scrawny of her two wings and into the net she goes.

There's no mistaking who the crowd's favourite is, but seeing off Sharapova is a difficult task.

    From deuce, Sharapova earns a break point but it vanishes after pin-point forehand shooting from the New Yorker. Double fault from Vandeweghe, then an iffy backhand. Second break point Sharapova - which the American again saves!

    Next up on Court One is Timea Bacsinszky against Garbine Muguruza.

    Swiss Bacsinszky, 26, came close to quitting tennis after foot and abdominal injuries limited her to just a few appearances on the tour between 2011-2013.

    She had already started training in hotel hospitality, when she got an email saying that he was eligible for French Open qualifying.

    She drove to Paris, gave it a crack, lost, but rediscovered her love of tennis. And now she is up to 15th in the world and into the quarters at Wimbleon for the first time after making the French Open last four earlier this year.

    Andrew Castle, he who reached the third round of Queen's in the 80s, is partnering Jeff Tarango in the senior gentlemen's doubles. The pair warming up on court 12. A teenager is texting on her smart phone as the seniors go through the motions. It could be a while for those old bones to limber up, she's thinking. Maybe.

    Sharapova 6-3 2-1 Vandeweghe

    Maria Sharapova

    Coco Vandeweghe has a champion's name but not yet a champion's nous. Maria Sharapova stealing three break points from the American. She could be toast. She is toast. Sharapova on course for the semi-finals.

    "There is a stir at the practice courts as Roger Federer and coach Stefan Edberg arrive. He starts hitting up on the court behind Murray's and is full of chat as he hits forehand after forehand, even complementing his hitting partner on the garish orange T-shirt he is wearing."

    Mark Woodforde

    Former Grand Slam doubles champion on BBC Radio 5 live

    Djokovic

    "It was a big relief for Novak to get through the match and perhaps that's why he was not as emotional as he usually is."

    "Kevin Anderson is just one big match away from being a real danger at Grand Slams in the future."

  158. Djokovic into the last eight

    Djokovic 6-7 6-7 6-1 6-4 7-5 Anderson

    Novak Djokovic talking to BBC Sport's Garry Richardson: "I think Kevin served exceptionally well. I found it one of the most difficult matches I've played. At times I was really helpless with my returns. He was very aggressive.

    "I thought it was high-quality tennis in the fifth set.

    "I was two sets down. To come back and win in five gives me great satisfaction and confidence for the next challenge."

  159. Cilic next for Djokovic

    Djokovic 6-7 6-7 6-1 6-4 7-5 Anderson

    It is US Open champion Marin Cilic next for Novak Djokovic in the quarter-finals.

    His record against the Croat is an imposing 12 unanswered victories.

    "I think Novak didn't really enjoy the match up until the match point when the ball went wide. It is nasty match for him.

    "It was mentally fatiguing for him to see someone hit big serves time after time. He did not get into any rhythm and will be so relieved to get through the match."

    "The overriding emotion for Djokovic has to be relief because that was terrifying. At times Anderson looked like he might be unbreakable but in the end a couple of double faults were his undoing. Djokovic was just too steely."

  162. Post update

    Novak Djokovic says that his meeting with Anderson was "one of the most difficult matches that I have played at Wimbledon in my career", adding that he was "helpless" on return at times facing the Anderson cannon.

    Full quotes to come.

    Well, Novak Djokovic won't need a shave for finals day if he gets there.

    Kevin Anderson came within a razor's width of taking out the top man, but Djokovic, as usual, just finds a way to win tennis matches.

    A framed forehand long from Kevin Anderson and it is 40-30 and match point.

  165. Game and first set

    Sharapova 6-3 Vandeweghe

    Sharapova with the opportunity to serve for the first set. She broke Vandeweghe immediately after the American had the temerity to get the better of the Russian's serve and in 43 minutes, the opening set is done and dusted.

  166. Djokovic serving for the match

    *Djokovic 6-7 6-7 6-1 6-4 6-5 Anderson

    How's that serving arm Novak? He slips to 0-30. Nervy, twitchy. But nothing wrong with that - a slapped winner for 15-30.

    "I hope Novak is good at writing thank you notes - those double faults were two donations from Anderson. He essentially gifted the break to Djokovic. It was a wonderful return of serve right at the big man's feet on break point and for once Anderson couldn't come up with the volley."

    A return right onto the big toe of big Kevin Anderson. The South African cannot scrape it off the deck and over the net.

    "Novak has looked a bit flat today which is not normal for a champion like him. Body language is important as it sends out a message to your opponent. At the moment it Novak's is encouragement for his opponent. He had a quick service game and maybe that'll get his energy back."

    Novak Djokovic is forced out wide by a battering Kevin Anderson backhand at 30-0, but out in the wings is where he does his best work.

    "He has come out with no nerves in the fifth set, just enjoying the occasion, taking the ball on. The crowd have not seen much of Anderson and they are saying what a player."

    Does anyone else hear the umpire's call of Anderson in the tone of the Matrix's Agent Smith menacing "Mr Anderson"?

    Kevin is the one doling out serves like a machine though. He has only lost one of his 20 first serves that have landed this set and a 40th ace of the match takes him to a hold to 15.

    Djokovic to serve to hold onto his title.

  176. Murray sledging during practice

    Paul Birch

    BBC Sport at Wimbledon

    Murray

    "After much conjecture over the format and rules, Murray and Bjorkman start a match that is first to 10 and doesn't have proper serves. Murray charges into a 5-0 lead but Bjorkman battles back and picks up four points, much to his delight. However, it ends 10-4 with the Swede chuckling away at Murray's relentless sledging towards him."

  177. Post update

    Djokovic 6-7 6-7 6-1 6-4 4-4 Anderson*

    Novak Djokovic finds a bit of steady ground on serve.

    A hold to love completed by a horrible framed forehand from Anderson that would have scared the pigeons more than Rufus the Hawk.

    We are heading to the death rattle. Not a lot of wiggle room for either man now.

  178. Vandeweghe breaks back

    Sharapova 3-2 Vandeweghe*

    Maria Sharapova

    A cute Vandeweghe backhand volley stirs the Centre Court crowd from their slumber, earning the world number 47 three break back points too against the former Wimbledon champion.

    Sharapova claws back one point... but, on the next, the New Yorker overpowers the Russian with relentless forehand hitting. The patrons on Centre rooting for the underdog, cheering as the quarter-finalist as she strides towards her chair.

    "Kevin Anderson often goes into his shell, doesn't hit the ball to the rafters and that's what costs him the matches."

    "It's just frustration for Novak. He is looking for a breakthrough and it's not happening. Anderson is hitting the ball the best that I have seen him hitting. Novak is hoping that Kevin Anderson's level might just drop a bit."

    The rain has eased off slightly.

    Certainly whatever is left in the SW19 heavens is not putting Kevin Anderson.

    Ace 39 of the match off his strings help the big South African to another hold to love. He has won 17 of 20 points on his serve in this set.

    No messing around from him.

    "Djokovic looked a bit flat in the first few sets yesterday before eventually getting it back. I noticed in Anderson's last service game that Novak was looking at his box. He is getting frustrated. That's what happens when you play big servers.

    "Look at how Andy played Karlovic. He just got down to it and bogged him down. Novak looks frustrated right now."

    "Anderson has got to be aggressive. Take chances early in the rally."

    *Djokovic 6-7 6-7 6-1 6-4 2-3 Anderson

    Djokovic

    Novak Djokovic punches a forehand down the line at 30-0 up, but is half a foot long. What could be 40-0 is 30-15 and Anderson has a glimmer.

    A mammoth rally breaks out - biff, bosh, back, forth, angles, spin, power, guile - 20 crafty clever stroke ended by Djokovic burying into the net. 30-30.

    It is getting drizzly. The court coverers are loitering. Djokovic is getting ratty.

    Chuntering away to himself, the champion clumps long to take us to deuce.

    Kevin Anderson's serve is still a thing of brutal beauty.

    Novak Djokovic reduced to Kyrgios style indifference as another two master-blaster serves cannon past him for aces.

    A hold to love. If Camp Djokovic hoped that Kevin Anderson would emerge today with a touch of vertigo, they have been disappointed.

    The South African is not fazed by the situation at all.

    Maria Sharapova

    Sharapova must fend off another break point, which she does confidently - arching an ace down the middle. The fourth seed's serve has yet to find its rhythm, but her inexperienced opponent - in a Wimbledon quarter-final for the first time - is unable to take full advantage, dragging her forehand wide at the critical moment.

    Novak Djokovic opens with a double fault, flops a forehand into the net and suddenly has an unappetising 0-30 to look at.

    "Breaking it down, Anderson has three weapons - serve, forehand, and his reach at the net. I mean, he is a comfortable volleyer at the net once he gets there."

    "Talk about a game of inches, it was a game of millimetres. It's interesting to note that over the first four sets he got about 55% of his first serves in, so far here it's around 75%. So the serve has been his dominant weapon thus far."

    Another rocket serve - this one clocking up 134mph on the speed gun - thuds past a line judge's temple and into the screens behind for a clean ace. Number 36 of the match and 30-15.

    Is Djokovic getting a better read on the serve? He dives out left to slap a return winner. That takes us to deuce.

    For all the talk of his own indomitable serve, Kevin Anderson has broken the Djokovic serve just once in the previous four sets. Djokovic has taken games against the head on four occasions.

    Anderson is not a serving lighthouse at a loss as soon as a rally breaks out though.

    He bungs a lovely forehand winner down the line to take one point off the Djoko tee-off. That is all he is getting though.

  204. We had to build confidence - Mauresmo

    Amelie Mauresmo is overseeing Murray for the final time before she goes on maternity leave. (She is due to give birth to her first child next month.)

    It's just over 12 months since she linked up the world number three and she says her first priority then was rebuilding his confidence in the wake of back surgery.

    "The first few months were about giving him confidence back. He needed to play a lot of tournaments and get back stronger physically," she told Lee McKenzie. "The team did a great job to get him back working again."

  205. Covers are removed

    Green, green grass. Lovely green, green grass. There's no protection hiding the green stuff on Centre, the net is upright, ball boys and ball girls are standing to attention, and the crowd cheer Maria Sharapova and Coco Vandeweghe onto the stage. Excellent.

    There is life on Court One.

    They peel back the taurpalin, ratchet up the net cord and wipe down the umpire's chair.

    "It looks like it is going to be on/off given the weather today. Novak, because he has been in so many situations like this, he will have the advantage as the higher-ranked player. For Kevin Anderson, he may have some added nerves but he has nothing to lose. Novak, by contrast, has only lost three times this year."

  209. We can beat France, says Smith

    Davis Cup

    As there's no live tennis to talk about, we'll turn our attention to the Davis Cup. Captain Leon Smith has been chatting to Sue Barker about next week's quarter-final against France.

    Andy Murray, brother Jamie, James Ward and Dom Inglot make up the GB squad at Queen's Club from 17-19 July.

    "We have a strong, close-knit team that is ready for the fight," says Smith. "France are the favourites but we believe we can win it."

    The tie will be broadcast live on BBC TV, radio and online.

  210. On or off?

    The soothing voice of one of the officials informs us, via the sound system, that the covers will, hopefully, be removed in 10 minutes, which means the roof will not be brought into action. Yet.

    BBC Sport at Wimbledon

    "Two minutes into practice and Team Murray scarper as the heavens briefly open. Fans take the opportunity to ask for a selfie, but Murray doesn't reply as he plays imaginary forehands. He is in the zone. Just needs the rain to stop."

  212. Fact of the day?

  213. Rain, rain, rain

    Wimbledon 2015

    The sky darkens which means it's time to welcome the rain-filled clouds. Brollies replace sunhats on Centre Court, Sharapova and Vandeweghe shoot off and the covers are quickly brought on. Time for the roof to earn its crust, perhaps?

  214. Play suspended on Court One

    Kevin Anderson and Novak Djokovic got as far as their courtside chairs and no further.

    Heavens partially open, brollies bloom and Novak Djokovic heads back to the locker rooms with a wry shrug.

  215. Murray watch

    BBC Sport's Paul Birch has been sent to keep a close eye on Andy Murray's practice session. "Almost time for Murray to hit the practice courts," writes Paul. "His coaches Amelie Mauresmo and Jonas Bjorkman have been deep in conversation while they wait. Bjorkman has been limbering up and doing the odd stretch as he prepares to watch Murray's winners to scorch past him. He is 43 after all..."

  216. Who is Coco Vandeweghe?

    Those of you who have done your homework will know Coco's name is Colleen but her friends used to call her "CoCo Puff". Her grandmother was Miss America 1952 and apparently taught CoCo how to walk in heels, which should be useful in the next few hours.
