22.12: Well, what a way to wrap up today's coverage. I need to go and catch my breath! We nearly had an historic upset when Brit James Ward took No 10 seed Mardy Fish to five sets earlier on, but this one far eclipses what that would have been. Rosol was absolutely on fire out there and would have beaten anyone in the world playing like that. The fact Nadal will not feel at all disgraced at losing that is the best compliment I can offer to the Czech. Join us tomorrow for live coverage of day five from 11.00am.

Lukas Rosol has beaten Rafael Nadal 6-7, 6-4, 6-4, 2-6, 6-4

22.06: Let me remind you, Nadal is not injured, and he has made less unforced errors than his opponent who is ranked 100, yes 100, in the world. Rosol is not a youngster coming up through the ranks either, he is nearly 27 years old! What an unbelievable match.

22.04: He's done it!!! Absolutely incredible. I've never seen anything like that on a tennis court. Nadal was absolutely blown away!

Czech mate: Rosol was in sensational form

Czech mate: Rosol was in sensational form

2.03: Three match points!!! Two aces and a brutal forehand set it up...

22.02: 15-0 - Ace down the middle.

22.01: Nadal just clings on again having been 15-30 down. He survives thanks to a favourable net cord at 15-30 and short second serve that's slammed into the net by Rosol at 30-30. But... the Czech will now serve for the match...

21.57: This is unbelievable... You would think Rosol was the one with all the Grand Slams. He breezes past Nadal to love with some more formidable hitting.

21.54: Rosol gets Nadal to 0-30 courtesy of two blistering returns that the Spaniard has absolutely no answer for. But the world No 2 shows his fighting qualities again to win the next four points and put the pressure back on the Czech.

21.50: Wow! Stunning from Rosol who holds to love, finishing off with two aces. Where has he been hiding?

21.48: Nadal is simmering out there, he seems furious with the umpire and his opponent, but it's not clear why... He holds to love again and is firing on all cylinders here. The key to this match is whether Rosol can keep up this masterful display of serving.

21.45: Nadal pegs back Rosol back to 40-30, but - as has happened so often in this match - just as you think Rosol is creaking he comes back, this time with a monstrous overhead to hold again.

Brutal: Rosol thunders down another serve

Brutal: Rosol thunders down another serve

21.41: This time its Nadal who holds to love, and he'll have a crack at breaking back after the changeover. Rosol, somehow, still looks as cool as a cucumber.

21.39: Rosol holds to love. Nadal, remember, is in Murray's half of the draw. The Scot has lost to him in the semi-finals in the last two years. Dare we dream?

21.37: He's done it! Who saw that one coming?! Rosol's forehands sound like fireworks exploding with the roof closed. Massive task on here to hold on though given the comparative experience of the two players.

21.35: I've put the score above to make it easier for you... I hope! Nadal loses the first two points of the deciding set on his serve. He fights back to 30-30 but Rosol earns a break point with a forehand right into the corner...

Ready to go: The roof is closed on Centre Court

Ready to go: The roof is closed on Centre Court

21.30: What an atmosphere it is under the roof... Nadal will serve first.

21.24: Querrey and Raonic went off at 3-3 and will continue their match tomorrow, meaning that this is the only singles match left ongoing. And it WILL finish tonight. What he have is effectively a one-set shootout, hold your breaths...

21.22: The players come back out to a rapturous ovation from the patient and expectant Centre Court crowd. They'll have to start all over again here and it's all about who starts quickest.

21.10: Cepelova and Garrigues will play their final set tomorrow, while Querrey and Raonic are still going on Court No 1 and they're still going with serve at 3-3, one set all. Rafa is back in 10 minutes...

Against all odds: Rosol has taken to Nadal to five sets

Against all odds: Rosol has taken to Nadal to five sets

20.59: Cepelova and Garrigues are playing on on Court No 12, as are Querrey and Raonic on Court No 1. I'm not sure how long those matches will last, but I'll keep you posted.

20.56: Jana Cepelova has taken the second-set tie-break against Anabel Medina Garrigues to take that one into a decider.

20.50: They're closing the roof on Centre Court to allow time for the fifth and final set to be played out between Rafael Nadal and Lukas Rosol. It will take up to half an hour for them to be ready to restart, so that's 9.20pm.

20.49: Sam Querrey has levelled up his match with Milos Raonic by winning a second-set tie-break.

20.46: Rafael Nadal has won the fourth set against Lukas Rosol to level the match at 7-6, 4-6, 4-6, 6-2: Exceptional defence from Nadal whose in that sort of mood where he looks like he could chase down a missile. He secures the set with a double-break.

Close encounter: Milos Raonic (above) is taking on Sam Querrey

Close encounter: Milos Raonic (above) is taking on Sam Querrey

20.44: The other two matches still out are now both in tie-breaks. I'd assume they'll be rolled over into tomorrow after the conclusion of the respective sets.

20.43: Nadal consolidates the break and Rosol will now serve to stay in the set. I wonder if they will close the roof and turn the lights on if it goes into a fifth? The only other option would be to play on tomorrow as it's starting to get dark now.

20.38: He's got it, and we look like we're heading into a fifth. It was a case of Nadal stepping it up with some brutal, deep groundstrokes, rather than Rosol choking.

20.37: Nadal has two break points at 3-2...

20.33: Medina Garrigues has been broken serving for the match against Cepelova and we could have a second tie-break in that match too.

20.32: Still no breaks of serve between Raonic and Querrey and we're heading for a second tie-break there. That on will go into tomorrow for sure.

Centre of attention: It's been a glorious day on Day 4 at Wimbledon

Centre of attention: It's been a glorious day on Day 4 at Wimbledon

20.29: Anabel Medina Garrigues is serving for the match against Jana Cepelova on Court No 12. Meanwhile, we're still on serve in the fourth on Centre.

20.24: Whenever Nadal thinks he's got his foot in the door, Rosol slams it shut. He had Rosol at 0-30 there but the Czech powered back to hold serve. Now Nadal knows how others feel when they play against him.

20.22: Just the three singles matches left out there then, but there's only one everyone is talking about. Nadal holds the opening game of the fourth to 30.

20.15: Lukas Rosol has taken the third set to lead Rafael Nadal 6-7, 6-4, 6-4: What a story this is turning out to be. Rosol has been leathering every single ball and is making Nadal look frankly average. If he keeps it up in the next set Nadal won't be able to stop him. The Spaniard made just one unforced error in that last set - that's how good Rosol is playing.

Fightback: Baltacha restored some pride in defeat to Kvitova

Fightback: Baltacha restored some pride in defeat to Kvitova

20.12: Petra Kvitova has beaten Elena Baltacha 6-0, 6-4: Poor Elena was never really in this one, getting off to a dreadful start and going on to lose the opening 10 games. She showed some fight though in the second set and restored a bit of pride.

20.10: Nadal holds to love... Rosol will now serve for the set. You feel whoever wins this game may well win the match.

20.08: Medina Garrigues has an early break and is looking well set to advance to third round. Rosol holds comfortably again and Nadal is now serving to stay in the third set at 3-5.

20.05 Nadal is clinging on in the third by the skin of his teeth. Rosol is holding to love with ease as Nadal scrapes two consecutive service games to 30. It's 4-3, Rosol serving.

Czech him out: Lukas Rosol was brilliant on Centre Court

Czech him out: Lukas Rosol was brilliant on Centre Court

20.00: Three games in a row now for Baltacha who trails 3-4. She can't, can she?

19.57: Baltacha has won another game! She's broken Kvitova and is now 2-4 down in the second.

19.56: Women's No 26 seed Medina Garrigues has taken the first set against Cepelova in a tie-break, while men's No 21 seed Milos Raonic has also won his first set on a tie-break against Sam Querrey. 

19.52: Rosol has the break and Nadal is fuming at the umpire for some reason or another... Regardless, he's now in a bit of bother and will need all of his fighting skills to get out of this one.

19.51: Lukas Rosol has three break points! What on earth is going on?...

19.49: Baltacha has won a game! Fair play to her, she's not given up in the face of some brilliant and brutal tennis from Kvitova.

In trouble: Nadal lost his second set against Rosol

In trouble: Nadal lost his second set against Rosol

19.45: Oh dear, Baltacha is now 6-0, 4-0 down and Court No 1 is emptying quickly.

19.40: Lukas Rosol has won the second set against Rafael Nadal 6-4: He's done it! Not a sign of nerves from the Czech there as he serves out to 15 and clinches it with an ace down the middle. Nadal has been pretty abject and will need to up his game as Rosol is clearly capable of capitalising on any opportunities he is presented with.

19.38: Nadal holds out and Rosol has a changeover to compose himself before serving for the set. He's simply got to take this chance.

19.36: Querrey and Raonic and Medina Garrigues and Cepelova are still going with serve in their opening sets. Meanwhile, Nadal is serving to stay in the second set at 3-5.

19.34: Baltacha has been broken in the opining game of the second set - she'll do well to win a game here the way this one is going.

19.30: Rosol has consolidated his break and is now 4-2 up in the second set. Plenty to do to take the set still though against a competitor like Nadal.

19.27: I've come back from a well-earned chicken salad to find Baltacha being absolutely annihilated by Kvitova on Court No 1. It looks very much like we'll have just two Brits left at Wimbledon very soon.

19.23: On Court 2 Kvitova has taken the first set against  Baltacha 6-0. And with that, I will hand you back to Joe.

19.22: Things are not all going Nadal's way on Centre Court, having been pushed all the way in the first set tie break he is now a break down Rosol. It could be a long night on Centre Court.

19.20: Things are going from bad to worse for Baltacha as she has yet to win a game and finds her self 5-0 down in the first set to Kvitova.

19.15: Another game is now underway in the men's side of the draw, on Court One USA's Sam Querrey is playing 21st seed Milos Raonic from Canada, it is 1-1 and going with serve after two games.

19.10: The other game out on court is Spain's Ana Isabel Medina Garrigues against Jana Cepelova. The match is going with serve over on Court 12 and is 3-4 in the opening set.

19.07: Bad news for Elena Baltacha as she is broken in her first service game and trails 2-0 to Kvitova early on in the opening set.

19.05: Nadal has won the tie break 11-9 and takes the first set after an hour on court.

Cruise control: Azarenka dropped just two games on the way to beating Oprandi

Cruise control: Azarenka dropped just two games on the way to beating Oprandi

19.01: Despite it being after 7pm, there is still plenty of tennis being played. Well, when I say 'plenty', there are three games on court. On Centre Rafa Nadal is in a first set tie break with Lukas Rosol. While out on Court No 2 Elena Baltacha is up against defending women's champion Petra Kvitova, that match is about to get underway.

18.55: Right, Joe is off for a break after that epic James Ward vs Mardy Fish match, so while he is off I - James Andrew - will be in the hotseat for the next half an hour or so.

18.52: Fish then will play Belgium's David Goffin in the fourth round. And Murray will face Marcos Baghdatis, who advances past Grigor Dimtrov after the Bulgarian retired from their match with the score at 7-5, 4-1.

18.50: Mardy Fish has beaten James Ward 6-4, 5-7, 6-4, 6-7, 6-3: What a fantastic effort that was from both players. Ward pushed Fish all the way and has an adoring Court No 1 crowd on their feet as he departs. Fish, meanwhile, has to be given credit for a gutsy performance in just his second match after having an operation on his heart.

18.48: No 5 seed Jo-Wilfred Tsonga is into the fourth round with a 6-7, 6-4, 6-1, 6-3 win over Guillermo Garcia-Lopez. Meanwhile, Nadal has been taken to a first-set tie-break by Lukas Rosol.

Viva Espana: Nadal whips a trademark forehand

18.45: Ward is broken and Fish will serve for the match. The crowd are urging the Brit on with everything they've got.

18.42: We're still with serve on Court No 1 but Ward finds himself 0-30 down at 3-4.

18.40: Victoria Azarenka is looking good for a tilt at the title after breezing past Romina Oprandi 6-2, 6-0. The No 2 seed plays the winner of Anabel Medina Garrigues and Jana Cepelova - who have just got under way on Court No 12 - in the fourth round.

18.36: No 31 seed Anastasia Pavlyuchenkova is out, going down 7-6, 6-4 to Varvara Lepchenko. Lepchenko faces the winner of Brit Elena Baltacha v defending champion Petra Kvitova.

18.33: No 9 seed and former US Open winner Del Potro has broken the plucky Japanese Soeda to win in four sets 6-2, 6-3, 1-6, 6-4. He'll face No 19 seed Kei Nishikori in the fourth round.

18.28: Rosol has broken back against Nadal on Centre Court - no mean feat, that.

Made to work: Fish squandered a match point against Ward in the fourth set

Made to work: Fish squandered a match point against Ward in the fourth set

18.25: We're still going with serve, somehow, between Ward and Fish in a typically bizarre fifth set of momentum swings between two tired players.

18.21: Nadal has broken Rosol in the fifth game of their match, while fellow No 2 seed Azarenka has a break in her second set against Oprandi and now looks nailed on for victory.

18.15: Tsonga has waltzed through the third set against Garcia-Lopez 6-1 and he's now just one set away from securing a fourth-round spot.

18.13: Azarenka takes the first set against Oprandi 6-2.

Decider: Ward has taken Fish to a fifth set

Decider: Ward has taken Fish to a fifth set

18.11: Fish has just saved two break points in the opening game of the deciding set and we're now at deuce... but Fish hols out with four points in a row.

18.10: Baghdatis is edging closer to that date with Murray and is now a set and a break up against Dimitrov.

18.07: Rafael Nadal and his Czech opponent Lukas Rosol are now out on Centre Court.

18.04: James Ward has taken the fourth set 7-6! Brilliant battling from Ward who has the crowd on Court No 1 spellbound. Fish looks shell-shocked after squandering that match point and he'll have to regroup before the deciding set.

18.02: Ward has three set points! He's dominated the tie-break and now has a chance to take this into a decider...

18.01: Two women's singles matches are currently going on. Lepchenko has taken the first set against No 31 seed Pavlyuchenkova on a tie-break, while second seed Victoria Azarenka has raced into a 4-1 lead over Romina Oprandi on Court No 2.

17.58: Tsonga now looks to be up and running against Garcia-Lopez and now has a break in the third set. Del Potro, by the way, lost that third set against Soeda 6-1, but he's 2-1 up in the fourth. 

17.56: Fish recovers from 15-30 down to take it into a tie-break. It's do or die here for Ward now.

Marching on: Murray faces the winner of Baghdatis v Dimitrov in the fourth round

Marching on: Murray faces the winner of Baghdatis v Dimitrov in the fourth round

17.53: Marcos Baghdatis has taken the first set against Grigor Dimitrov on Court 12. Murray awaits the winner of that one in the fourth round.

17.51: Tsonga has taken the second set 6-4 to level things up against Garcia-Lopez over on Court No 3. The winner of that will face Slovakian Lukas Lacko - who beat the veteran Jurgen Melzer in five sets earlier - in the fourth round.

17.48: Philipp Kohlschreiber has wrapped up a straight-sets win over Malek Jaziri 6-1, 7-6, 6-1.

17.47: James Ward has broken back! He survives a match point against Fish and they're now 5-5 in the third.

17.43: Incredible scenes over on Court 18 where Juan Martin Del Potro, who was seemingly cruising to victory at 6-2, 6-3 up against Go Soeda, is 5-0 down in their third set.

Job done: Murray hails his win over Karlovic

Job done: Murray hails his win over Karlovic

17.40: Andy Murray is through to the fourth round with a 7-5, 6-7, 6-2, 7-6 win over Ivo Karlovic: It's there! That wasn't easy by any stretch but it's job done for Murray, who crucially avoids a gruelling fifth set. He'll be still be tired after that one though - it was a real slog at times.

17.38: Two match points! Murray somehow wins a couple of sloppy points thanks to a couple of Karlovic errors and is now on the cusp of victory.

17.36: Karlovic gets the mini-break back thanks to a couple of brave volleys. Crucial few points coming up.

17.34: Mardy Fish has broken James Ward and is now serving for the match at 5-3. Meanwhile, Murray has the mini-break in the tie-break.

17.31: We have ourselves another tie-break...

17.28: Murray is serving to take the fourth set into a tie-break. He's not had a sniff on the Karlovic serve this set.

Frustration: Murray lost momentum in the fourth set

Frustration: Murray lost momentum in the fourth set

17.24: Andy Roddick has beaten Bjorn Phau 6-3, 7-6, 6-3 to set up a probable fourth-round clash against David Ferrer. Kohlschreiber already has a break in the third against Jaziri and Del Potro is now two sets up against Soeda. The men's fourth draw is taking shape nicely.

17.19: Roddick has overturned Phau's break in their third set and he's now just one game away from victory. Meanwhile, Kohlschreiber has taken the second against Jaziri and we're still on serve on Centre - Karlovic leads 5-4.

17.16: Marin Cilic has dispatched of Lukasz Kubot 7-6, 6-2, 6-1. He has faces the winner of Sam Querrey v Milos Raonic next.

17.14: We're still in serve in the fourth set on Centre, where Karlovic has done well to bounce back from the pasting he took in the third. He' five games away from another tie-break - where he will fancy his chances.

Toiling: Ward lost the third set against Fish on Court No 1

Toiling: Ward lost the third set against Fish on Court No 1

17.10: There's a potential upset on the cards on Court No 3, where the popular Frenchman and No 5 seed Jo-Wilfred Tsonga has lost a first-set tie-break to Guillermo Garcia-Lopez.

17.05: Something I think may have been missed in the turnover between Mr Metcalfe and myself was the news that women's No 9 seed and former Wimbledon finalist Mario Bartoli is out. She has lost in straight sets to Croatian Mirjana Lucic - who had to qualify for the tournament.

17.02: Nadia Petrova has won a gruelling third set against Timea Babos to advance into the third round of the women's draw. We're still with serve on Centre in the fourth.

16.58: Mardy Fish takes the third set against James Ward to lead 6-3, 5-7, 6-4: Ward had managed to stave off several break points in the third against the No 10 seed, but he's finally broken and it will take a monumental from here for the Brit to win.

16.55: The dangerous former US Open winner Juan Martin Del Potro has made a flying start against Go Saeda and is already a set and a break up. Also in Murray's side of the draw, Cilic has a break in the third against Kubot and should have that one wrapped up imminently.

16.51: Andy Roddick has come through a second-set tie-break against German Bjorn Phau to lead two sets to love. If the No 30 seed wins that he could face a mouth-watering fourth-round clash against David Ferrer - the No 7 seed and Andy Murray's conqueror at the French Open.

16.48: Andy Murray takes the third set against Ivo Karlovic to lead 7-5, 6-7, 6-2: No mistakes from Murray serving that one out and it's surely just a matter of time now against the tiring veteran.

16.46: There are just two women's singles matches going on at the moment. No 20 seed Nadia Petrova is 7-6 up in the deciding set against Timea Babos, and No 31 seed Antastasia Pavlyuchenkova and Varvara Lepchenko have just under way on Court 17.

Off to a flyer: Murray stormed through the third set

Off to a flyer: Murray stormed through the third set

16.42: Murray breaks! Fantastic speed from Murray as as he forces Karlovic to volley into the net at break point and the Scot will now serve for the third set at 5-2.

16.38: Cilic has taken the second set against Lukasz Kubot 6-2, and that one appears as good as over. Ward and Fish are going with serve in their third set with the score a one set apiece.

16.33: No 22 seed Alexander Dolgopolov is in serious danger of going out. He is now 7-6, 6-4 down to Frenchman Benoit Paire. Meanwhile, Murray is serving on Centre, 3-2 up in the third.

16.29: Marin Cilic - who is in Murray's half of the draw -  is now a set and a break up against Kubot on Court 4.

16.25: Murray is still not firing on all cylinders out there but he clings on to take a 2-0 lead in the third after being taken to deuce on his serve. Elsewhere, No 27 seed Philipp Kohlschreiber has taken his first set against Malek Jaziri 6-1.

Fighting back: James Ward took the second set against Mardy Fish

Fighting back: James Ward took the second set against Mardy Fish

16.20: Murray breaks! The Scot hits back immediately by breaking Karlovic to 30 in the opening game of the third set. The game is secured with a delightful lob after Murray had drawn the Croat into the net.

16.17: James Ward wins the second set against Mardy Fish 7-5: Just as one Brit's chances suffer a setback, another's are boosted as Ward gets right back into his match against Fish with a late break in their second set.

16.14: Ivo Karlovic wins the second set against Andy Murray 7-6: Game on! Karlovic's best chance in this match was always to take it to tie-breaks, and he's done exactly that. Murray missed a bread and butter pass at 5-5 in the breaker and the Croat capitalised on a Murray's second serve at set point to level things up.

16.10: Points are traded in the tie-break until Murray nets to fall 3-1 behind. But the Brit claws his way back into it to ensure the two are level at the changeover.

Scorcher: Fans bask in the Wimbledon sunshine

Scorcher: Fans bask in the Wimbledon sunshine

16.05: Murray holds to force the giant Croat to serve to stay in the set again. The Scot gets to 30-40 but goes long with a forehand and we have a tie-break. Ward meanwhile has levelled at 5-5 in the second set, decent comeback there.

16.00: That's all from me, but the extremely likable Joe Ridge is on hand to guide you through the afternoon and evening from here. Tally-ho.

15.58: Karlovic levels the second set at 5-5.

15.55: Murray has been keeping his nose in front in the second set. This match is a little short on genuine entertainment to be fair, with the Scot now 5-4 ahead.

15.47: Jamie Ward has been broken in the second set, and he's 3-1 behind against Fish.

15.45: A wee bit of good fortune for Karlovic on Centre Court, as he benefits from a net chord with a volley and levels the second set at 3-3.

15.40: Gilles Simon has had more to say about that old chestnut of equal pay.

'Men's tennis is more interesting than women's tennis, and it's not just my point of you, it's the point of view of everyone in the locker room, the media.'

15.32: We're going with serve in the second set on Centre Court, but Karlovic seems to be getting rattled by one or two calls. It's damn hot work out there now by the way, the humidity is pretty unbearable this afternoon. I know, I know, the British just love to moan about the weather.

15.28: Doubles partners Heather Watson and Laura Robson have been practicing at Wimbledon this afternoon.

Brit of all right: Heather Watson and Laura Robson

15.25: Another result for you: Belgium's David Goffin has beaten the American Jesse Levine 4-6, 6-4, 6-1, 6-3.

15.17: James Ward loses the opening set 6-3 against Mardy Fish. He wasn't expected to greatly trouble Fish today, to be fair.

15.15: Andy Murray wins the first set 7-5

The Scot will be delighted to avoid a tie-break as he takes full advantage of a set point this time, and takes a crucial advantage in this second round clash.

15.10: Murray again goes ahead 6-5 and is once again just one game away from winning the first set.

15.06: Karlovic slips 15-40 behind, but shows impressive nerve under pressure to save two set points and level at 5-5.

15.00: Murray edges 5-4 ahead, putting pressure on the Karlovic serve. He's started to settle into his service games out there now.

14.57: Remember Gilles Simon, he of the equal pay comments? He's been knocked out at the second round stage, beaten 6-4, 6-4, 7-6 by  Xavier Malisse.

14.55: It's still going with serve on Centre Court, and they're level at 4-4 in the opening set.

14.50: One of my favourite colleagues Martin Domin has just whispered 'James Ward is off to a flyer' to me, but I'm afraid it's pure sarcasm from the Scotsman. Mardy Fish has won the opening three games of their second round clash.

14.47: Ahh, they've settled down on Centre Court now, and both hold serve for the first time in the match.

14.43: There's a funny old bunch on Centre Court today...

14.41: Don't worry folks, he's broken straight back has Andy. It's 1-1 now.

14.35: Murray serves first, and has a spot of bother, losing a 40-15 advantage and four points in a row to go an early game behind.

14.30: Both Andy Murray and James Ward make their way out, on Centre Court and No 1 Court respectively.

14.25: Here are some words from Anne Keothavong:

'She (Sara Errani) ran away with it. It's Wimbledon, you're always a bit nervous. Had I made a better impression at the start, who knows how i would have got on? We are (the British players) all capable of playing better tennis, but you've got to put it into perspective, today I played a grand slam finalist. I'm just so excited about the Olympics now, I've worked so hard to make the team.'

14.14: Match point for Maria... and she doesn't need asking twice. It wasn't easy but that third set was evidence enough that the former champion will be a force to be reckoned with.

14.13: Game, set, match Miss Williams. Serena races through and you know what that means... it's time for Andy Murray.

14.10: Both Williams and Sharapova are one game away from winning their matches. A terrific response from the Russian but Pironkova will be kicking herself.

14.03: Over on Centre, we're with serve at 4-4 as Williams looks to close her second-round match out.

14.00: And another break for the Russian puts this match in little doubt. Can someone please send for Pironkova? She seems to have gone missing.

13.58: Sharapova wastes no time in getting back on track as she breaks serve in the first game of the second set, and backs it up by holding her own.

13.48: Meanwhile, on Court 2, David Ferrer, conqueror of Andy Murray at the French Open, has taken the first set against Kenny De Schepper.

13.46: She might have squandered five set points in the first set, but this time Pironkova gets the job done. Sharapova pulls two back after finally remembering how to serve but can do nothing to prevent this one going into a deciding set.

13.45: Utter shambles from Sharapova on her serve here. She falls 4-1 behind on the tie-break after three double faults. Pironkova piles on the misery by taking the next two points.

13.42: Serena Williams has raced through the first set 6-1 on Centre. David Beckham may not be going to the Olympics but one man who is is Andy Murray and he'll be on court in around forty five minutes I reckon.

13.40: We'll have a tie-break on Court 1 as Pironkova holds serve to keep the pressure on Sharapova.

13.32: Sharapova and Pironkova locked at 5-5 now in the second set.

13.27: Serena has broken on Centre Court, and has a 4-1 lead in the opening set.

13.20: Maria Sharapova has resumed her match against Tsvetlana Pironkova, where she is one set up. She has been broken in this second set however, and they're level at 4-4.

13.10: Serena Williams is on Centre Court for the first time this tournament. She's up against Hungarian qualifier Melinda Czink, and should win easily enough.

13.05: A women's singles result for you: Italian Roberta Vinci has beaten New Zealand's Marina Erakovic 6-4, 6-1.

13.02: What a nice man Stefan Edberg is. The Swede is being interviewed on television. Some fine memories flood back of his glorious singles finals against Boris Becker. I was always a Boris man, but that was a golden time.

12.52: Oh no, say I as an interview with Sir Bruce Forsyth comes on television, chatting with 1952 Wimbledon champion Frank Sedgman. But of course he makes me laugh, as he leans over a barrier and shouts 'I'll be with you later' to a group of punters. It all goes a lot better than his torturous appearance with Andrew Neill during the BBC's 2012 General Election coverage.

12.46: Anne Keothavong has been knocked out of Wimbledon

Sara Errani wins 6-1, 6-1. A splendid showing from her, and a bit of a tennis lesson for Keothavong. One Brit down, but a fair few still to come.

Two sides to every story: Sara Errani (left) easily beat Anne Keothavong (right) on Court Two

12.35: Errani has broken serve in the second set, and now leads 3-1. This one will be done and dusted soon.

12.25: Look who's shown up at Wimbledon. It's only Pippa Middleton. Here she is arriving, with her brother James...

12.20: Andy Murray is also out there practicing ahead of his big match. The courts are all starting to fill up across the All England Club.

12.15: It's all one-way traffic on Court Two. Errani wins the first set 6-1 and Keothavong will have to up her performance significantly to have a chance here.

12.05: Laura Robson is out there on the practice courts. She is in doubles action with Heather Watson later.

11.57: Errani has taken the first two games on Court Two. There are still thousands of empty seats by the way.

11.50: Keothavong is under way in her match. She's right up against it though.

11.45: I'm watching pictures of Virginia Wade and John Lloyd speaking with Sue Barker, with people in the background setting up picnics and trying to gain a good vantage point in front of the big screen. Pure Middle England.

11.35: Rafael Nadal is also in action later, against Czech player Lukas Rosol. Whisper it quietly, but this might just be the most interesting day of the tournament so far.

11.25: There's plenty of British interest on this fourth day. James Ward takes on Mardy Fish first up on Court One. Anne Keothavong plays Sara Errani first on Court Two, and that match begins shortly.

11.15: It's an absolutely lovely day here in London by the way. It feels genuinely hot out there.

11.10: Come on, Andy. That's something that might well be heard at Wimbledon today. Murray is in second round action against Ivo Karlovic. To mark your card timings wise, the match is second on Centre Court after Serena Williams plays Melinda Czink. With that first match beginning at 1pm, we expect Murray to begin some time between 2pm and 3pm.

11.00: If I'm not mistaken, the time has ticked round to eleven o'clock. It's time for day four of Wimbledon. Yes. you're invited too.

Rosol is a brilliant player but is it acceptable for him to spit during a match, Surely this should be stopped!

Take a look at Nadal just before serving and receiving, pick pants out bum, touch nose, ear,nose ear. Serious case of OCD me thinks - Mel, Poole, 28/06/2012 19:01 Its all down to sports psychology. Watch all the top players in most sports and they have routines. Johnny wilkinson is one. Remember what he did before kicking penalties. The same with folders pick o e and then watch home playing his tee shots with drivers. He will do the same thing overand over.

Pete, Sheffield You've obviously got far too much money and no sense at all. Will you marry me? :)

Stuck 1500 quid on Rosol at 28/1 to beat Nadal after seeing him at Queens. Merry Christmas!!! - pete, sheffield, 28/06/2012 21:18 Just had to say... That it ridiculously impressive! Congratulations you deserve every penny!

u can't deny it's makes such a such good viewing when u see a seeded play knocked out

Rosol Is awesome Nadal is petulant! When he is not playing well he uses every delay tactic in the book please beat him Rosol!

I have to watch Sharapova matches with the sound off.

I agree with Gilles Simon, men should be paid more prize money in the grand slam events.They have to play up to five sets, and has anyone ever seen the women's equivalent of Isner v Mahoot at Wimbledon?? come on ladies, dont be greedy!
