21:06The ever observant @RafaelNadalFC pointed out that Rafa Nadal has been using a boat called 'Williams' on his holiday in Ibiza. Maybe Serena could join him...? With that, I'm off, see you tomorrow for more.
21:04Tell you what, there might be a few earth-shattering upsets at this tournament but there are some tasty-looking quarter-finals "on tap" for the next couple of days.
21:02It was as if Wimbledon planned it like this. As darkness descends, the scoreboard clears and all matches are over. Tomorrow on Centre: Radwanska v Li Na, Kvitova v Flipkens. And on No.1: Lisicki v Kanepi, Stephens v Bartoli.
20:56Lisicki v Kanepi, Radwanska v Li, Stephens v Bartoli, Kvitova v Flipkens.
20:54Djokovic v Berdych, Ferrer v Del Potro, Kubot v Janowicz, Verdasco v Murray.
20:52"I lost to him the only time we played on grass here. But look, I think that I'm playing really really good tennis, maybe even better than 2011 when I won this tournament. I'm trying to maintain this level and hopefully I'll succeed."
20:49"He's always tough and I knew coming into the match, I had a bad record against him on grass. He's a grass-court specialist - he has great variety in his game, he can come to the net. It was tough but I played a really good match."
20:46Almost at the same time, Tomas Berdych wraps up an impressive win against another dangerous opponent in Bernie Tomic. It will be a Berdych-Djokovic quarter-final on Wednesday. Sounds good to me...
20:44Despite a shaky finish, Novak Djokovic joins Andy Murray and Juan Martin Del Potro in reaching the quarter-finals without dropping a set. Tommy Haas saves two more match points but Djokovic finds a big cross-court forehand to take a fine win over a dangerous opponent.
20:42Tommy Haas lets out an ear-piercing scream as he switches sides trailing 5-1 in the tie-break.
20:38I can smell the fear from the Umpires' Office from here. Wishaya Trongcharoenchaikul beats Thomas Colautti in three sets and will face Johan Sebastien Tatlot next... Good luck, umpire, whoever you are.
20:36Djokovic's radar is a bit off, and Haas is taking full advantage. The German holds to 15 and we go into a third-set tie-break. Tomas Berdych is a break up in the fourth against Bernard Tomic.
20:32Tommy Haas serving to stay in the match at 6-5 down in the third...
20:28Tommy Haas saves a match point on his way to holding for 5-5 against Novak Djokovic. Centre Court crowd absolutely loving this unexpected late drama...
20:25The Golden Bear Jack Nicklaus an interested observer on Centre where Haas is fighting for his life against Djokovic. Europe's Ryder Cup hero Ian Poulter is also in the Royal Box today.
20:19Well, well. Serving for the match, Novak Djokovic messes up two forehands to be broken. He now leads 5-4 against Tommy Haas.
20:16"Playing first match at 1pm on court no1 vs Kanepi tomorrow! Looking forward to the match and hope to see many of you out there again!"
20:13Tomas Berdych serves out the third set to take a two sets to one lead over Bernard Tomic. Novak Djokovic has broken and leads 5-2 against Tommy Haas, one game from victory.
20:08Wishaya Trongcharoenchaikul and Thomas Colautti have gone into a deciding third set in their boys' singles on Court 5. Bet the umpire's delighted about that.
19:59Tomas Berdych has the break in the third set against Bernard Tomic, leading 5-3. Fabulous match to watch - outrageous winner, laugh-out-loud mistakes, it's got it all. Novak Djokovic and Tommy Haas are on serve midway through the third, the Serb leading by two sets. We've got about an hour of light left by the way.
19:57It's only right we annoint a #MarathonMan on #ManicMonday and that man is Ivan Dodig. He went four sets with David Ferrer earlier - which is never much fun - and now he and Marcelo Melo have just won their men's doubles 6-4 in the fifth. Go Dodig!
19:50"It's going to be a special match because is going to be against Murray here in Wimbledon in quarterfinals. I'm going to go out there and try to do my game like I did every match and like I try to do every match that I play. But I know is going to be, of course, a tough match. He's No. 2 of the tournament. He's a great player, one of the best players in the last years on tour."
19:46The turnaround is complete. Poor approach from Tommy Haas on break point and Novak Djokovic picks his spot with a forehand pass to win four games in a row and take the set 6-4.
19:42Oooh, there's Eddie Redmayne - star of Les Miserables - looking very dapper in suit and straw panama hat. Yet another rumour that One Direction were due to visit today - but still no sign. Must've gone in a different direction...
19:41Novak Djokovic finds the outside of the line with a raking backhand to break back and he then holds to lead 5-4 against Tommy Haas.
19:32It's about time for another in this irregular series... Head to Boris Becker's Facebook page for pictures of BB dressed as a Royal Mail postman. Why? Why on earth not, BB would surely reply.
19:30On Centre, Tommy Haas is fighting back, leading by a break and 4-2 in the second after losing the first 6-1 against Novak Djokovic.
19:27Sizzling forehand by Bernard Tomic brings up three set points against Tomas Berdych. The first two are on his serve, but he can't take either of those. Fortunately for him, Berdych obligingly boots an easy forehand over the baseline and it's one set all on No.1
19:20Some jaw-dropping stats from Twitter earlier - almost as jaw-dropping as Serena's defeat. Her loss to Sabine Lisicki led to a spike of 2,500 tweets per minute. On Facebook, the official Wimbledon page's post about Serena's exit had 12,500 likes within an hour. #WildWimbledon continues...
19:13We may have found a winner in our search for a longer name in tennis than Wishaya Trongcharoenchaikul (see 1850 entry). It's Madagascar Fed Cup player Nantenaina Ramalalaharivololona - thanks to @RafaelNadalFC and @_ARRRT_ for digging that one out.
19:12"I saw that actually a few minutes ago. But I think it doesn't mean anything, especially here. So many weird scores."
19:08"Is very special. I'm so, so happy for be in the quarters for first time. I'm so exciting to be in that group, the only eight players going to be playing the quarters...I'm really like to play on grass at the moment. I think I improve my game here."
19:06Mike and Bob Bryan stay on track for a historic Siblings Slam. The US, Australian and French Open holders beat Treat Huey and Dom Inglot 7-5, 6-3, 7-6.
19:03"I think I play good three matches and four matches. Good level of my game. Yeah, I didn't beat Andy (Murray). Was pretty good match for me. Again, it was fourth round, but... But it's OK. Actually, it's nothing special right now for me from previous Wimbledons."
18:54Novak Djokovic wraps up the first set in 25 minutes over Tommy Haas. Laura Robson is back on court after her earlier singles defeat. She and mixed partner Colin Fleming are into a deciding third set against Polasek/Husarova.
18:50On Court 5, Wishaya Trongcharoenchaikul is in action against the woefully short-named Thomas Colautti of Britain in the boys' singles. Can you remember a longer name in tennis? Email me on email@example.com
18:45Centre Court: Radwanska v Li Na, Kvitova v Flipkens. No.1: Lisicki v Kanepi, Stephens v Bartoli.
18:43Um, so Tommy Haas had points to break right back, couldn't do it, and now is broken again. He trails Novak Djokovic 3-0.
18:36Tomas Berdych - having saved a set point - clinches the tie-break and the first set against Bernard Tomic. Novak Djokovic has broken in the first game against Tommy Haas.
18:33Kimiko Date-Krumm and her Spanish partner David Marrero beat Britain's Heather Watson and Jonny Marray 6-3 in the third to move into the third round of the mixed.
18:30This is why I love #ManicMonday. It already feels like we've had more than a day's worth of top tennis: we still have the rest of Tomic-Berdych and the whole of Haas-Djokovic to come... Date-Krumm fans, I have good news for you coming up...
18:25Bernard Tomic brings up his first break point of the match - and wouldn't you know it, it's a set point too. Tomas Berdych powers to the net to put away the volley. Tie-break time. I have a feeling these two names could give me problems: it's BerTom v TomBer.
18:20"I feel great. I really played four very, very good matches. I think I played better with each match. I get more and more confident with my strokes, as well as my game. So I am looking forward to playing tomorrow again. "
18:17"I don't take anything for granted. I know how hard these tournaments are to win, to play well in. I don't expect to come in to win them - there's no guarantees, you just keep trying hard...Serena Williams lost today and she doesn't lose too often, Roger lost, Rafa lost. All these guys and girls are better players than me and if they can lose then so can I."
18:11Not as easy as the scoreline might suggest. Andy Murray comes through a scratchy patch in the second set to take his grass-court winning streak to 15. He faces Fernando Verdasco in Wednesday's quarter-finals, hoping to improve his 8-1 winning record over the Spaniard.
18:04Youzhny with a big fist pump as he finally puts away the smash - at the third attempt - to save a break point but then he dumps a backhand in the net to give Murray a 5-1 lead. Berdych and Tomic going with serve on No.1 Court.
17:57Excited to be back in time for Berdych v Tomic - which could be a Christmas cracker. And if you have a spare five minutes, I need to recommend you look at the time-lapse videos on the Wimbledon website: of Henman Hill and the outside courts. On the second one, you can basically watch a whole day's play in a minute. Brilliant!
17:53Murray breaks! He leads Youzhny 2-0 in the third set. And with that, Caroline Cheese is done "breaking" (AKA taking a nap under her desk) and is once again your blogger of a live variety. Cheers!
17:48Tomas Berdych and Bernard Tomic are under way in their fourth-round match on No.1 Court. This is their first-ever meeting.
17:45Yeah, it's unbelievable what is going on right now. We have this moment two players in quarterfinal in men's draw. Maybe in a few minutes we'll have a woman in the quarter-finals [Radwanska won]. I think this is by far the best that possibly could happen to Polish tennis ... It's magical.
17:43Youzhny is back up after getting his shoulder worked on on the ground. The third set is under way.
17:38I was so nervous I couldn't close the match. I missed some forehands. But I was able to close my match with my serve. I'm improving on grass courts, I like it a lot. My quarter-finals is going to be very difficult against Ferrer, he's playing really well. He's playing fantastic himself - he's the favourite.
17:38Trainer is on court for Youzhny, who looks to be dealing with a right shoulder/upper arm issue. Murray is changing shirts.
17:35Andy Murray wins the final four points of the second set to take it 7-6(5). He now has a two-sets-to-love lead on Mikhail Youzhny.
17:30The Argentine is into the quarter-finals, where he will face David Ferrer. The Spaniard leads their head-to-head 4-2 and is 2-0 on grass, including in the fourth round here a year ago.
17:28Won an unbelievable battle! @serenawilliams is such a great player! The journey continues tomorrow! Lets go
17:27Murray and Youzhny are into a second-set tie-break, Andy having won the first set 6-4.
17:22It definitely happens. Crazy things happen at tournaments. Unfortunate that she lost, being the defending champion. But I think this has been a crazy Wimbledon. Uhm, I don't know, it's definitely tough. But I think there's a lot more other tournaments.
17:14Here's the match-ups: Lisicki vs. Kanepi, Radwanska vs. Li, Bartoli vs. Stephens and Kvitova vs. Flipkens. See the ladies' singles draw here.
17:13That's very nice of her. I don't know. I have a couple more matches to go till that happens. So just going to go out and play my hardest and see what I can do.
17:11Not so fast, Mikhail Youzhny. Andy Murray gets the break back in the second set and will serve to stay in the set at 4-5. Centre Court has come back to life under the sun.
17:08On rolls the Pole, who becomes the third from her country in one day - joining Lukasz Kubot and Jerzy Janowicz - to advance to the quarter-finals. The 2012 finalist will face Li Na.
17:04Radwanska holds at love for a 5-3 final-set lead. Can Tsvetana fight h er way back in this one? Li Na awaits the winner in the quarter-finals.
17:00Last I looked Murray led Youzhny 2-1 up a break in the second set on Centre Court, but the Russian has turned the tables and is now up 4-2. Reportedly a flat, lifeless feeling on the big stage right now. C'mon, AN-DAY!
16:57Sloane Stephens on Serena's loss: "This has been a crazy #Wimbledon." On Bartoli: "It will definitely be tough."
16:55Juan Martin Del Potro takes a two-sets-to-love lead on Andreas Seppi on No.1 Court, winning the second set 7-6(2). Seppi is 7-0 in five-set matches in 2013, but he'll have to come back from quite the deficit to win this one.
16:51Who's it going to be in this one? One final place is left in the quarter-finals and the 2012 finalist is trying to book it vs. the grass-loving Pironkova, but Tsvetana has twice been to the last eight, including a semi-final appearance in 2010.
16:44Question: Why didn't you wave to the crowd when you walked off the court?
Laura Robson: I was just trying not to cry.
16:43But, yeah, it's just been this overwhelming experience. Yeah, it's been crazy but in a good way. You know, I'm hoping to do better next year... I would have loved [for the crowd] to be even louder.
16:42I'm really, really disappointed. Uhm, you know, I thought she played a really solid match. She can hit the ball incredibly hard off the ground, so it was tough for me to stay in the rallies. But, you know, I had my chances here and there and I just didn't take them.
16:35OK good blog fans, I'm combing through the Robson press conference transcript to bring you the best (saddest?) quotes. Was a hugely disappointing loss for Laura. Grab the tissue box?
16:322007 Wimbledon runner-up Bartoli is into the quarter-finals with a convincing win over Knapp. Bartoli will face the lone American in the men's or women's singles - Sloane Stephens.
16:28Yes, Caroline, the ball boys and ball girls are honoured at the end of The Championships. I just wish we had one in our office to bring me water and a snack between changeovers. What? Do you think I'm asking too much?
16:28I was wondering if the ball boys and girls are being positively acknowledged at some point by the players?
They just do a phenomenal job!!!
16:24Into the quarter-finals goes former top 10 resident Verdasco, who is actually in his fourth final eight at Wimbledon in his career (shocker, I know!). The left-hander gets the winner of Murray-Youzhny, who are on Centre Court now.
16:18I'll sign on with a little by-the-numbers post: Murray serving for the first set on Centre vs. Youzhny. Del Potro up a set on Seppi on No.1 Court. Radwanska has won the second vs. Pironkova on No.2 Court. Verdasco up two sets on De Schepper and Bartoli a set and a break up on Knapp.
16:12OK, I need a moment (or an hour) to digest Serena Williams' exit. Luckily, Nick McCarvel is a lot more grown up than me and is better able to cope with such shocks...
16:11"Serena in grand slams without Venus: 4R, 4R, W (2007 Australian), 4R and this year, 4R."
16:08"I'm 31...! I think I'd really have to go the drawing board if I can't compete without them."
16:03Serena Williams won 99 points to Sabine Lisicki's 96. But in this case, points don't win prizes. "I'll have to go back to the drawing board," Serena says. "And work out a way to win this match next time."
16:00"It's not a shock: she plays really well on grass, she has a massive, massive serve, so you have to know it's not going to be an easy match. If's definitely something that's not a shock, I just need to do better."
15:58"I didn't play the big points good enough - I didn't do what I do best. I had a little hesitation and that explains it...Sabine played really well, she always does on grass... I definitely had my opportunities and I didn't take them."
15:55"Lisicki is my pick to win it. Thanks to the Live Blog and Wimbledon Radio for keeping me fist-pumping at my desk and getting me strange looks from my colleagues"
15:52Sorry, I sort of forgot the tennis was just carrying on while we all sat open-mouthed trying to take in Serena's defeat... Andy Murray is a break up on Mikhail Youzhny in the first set, likewise Juan Martin Del Potro against Andreas Seppi. Marion Bartoli is a set up against Karin Kanpp. But seriously: Serena Williams isn't going to win Wimbledon. Whaaaa...?
15:47"Wow- blown away by Lisicki- she held up under pressure and beat the defending champ and overwhelming favorite, Serena Williams. Congrats."
15:36Wow. Still taking it in... Serena Williams was one of the biggest favourites for this title we've ever seen. She had a 75-3 record since losing in the first round of the French Open last year. She'll head to the US Open "stuck" on 600 Grand Slam match wins. One of these players will be lifting the Venus Rosewater Dish on Saturday: Lisicki, Kanepi, Radwanska, Pironkova, Li Na, Stephens, Bartoli, Knapp, Kvitova, Flipkens.
15:33The United States has one quarter-finalist... and it's Sloane Stephens, who recovers from a set down to see off Puerto Rican teen Monica Puig and reach her second Grand Slam quarter-final.
15:24"I'm still shaking...(sobbing)...I'm so happy. Serena played a fantastic match, she's such a tough opponent, it's just an amazing feeling to win this match. The crowd were so amazing. I love this court so much, such a special place."
15:22"In her last 4 appearances @Wimbledon Lisicki has defeated reigning Roland Garros champion (Sveta '09, Li '11, Sharapova '12, Serena '13)"
15:18Of all the 'can't-quite-believe-what-I'm-seeing-moments' at this Wimbledon, I think this one might top it... Serena Williams' bid a sixth Wimbledon title and a 35th straight win is over.
15:13Another smash for Serena to look at - and this time, she goes well inside the lines to peg Lisicki back to 30-30. Fabulous serve out wide and it's match point Lisicki. Ah. Lisicki overcooks one. Back to deuce - and now a double fault. Eeek. ACE! Back to deuce, and now another huge serve that Serena can't handle. Match point number two - AND SHE'S DONE IT! Serena Williams is out of Wimbledon!!!
15:09Lisicki with a break point for a 5-4 lead - but Serena finds a first serve and the return goes into the net. Here's a second break point though after Serena stumbles while chasing a drop shot. Lisicki breaks and will serve for the match after Serena goes just long with an overhead... Sheesh...
15:03Here goes Lukasz Kubot and his famous can-can dance. It's the first time in history there have been two Polish men in a Grand Slam quarter-final. They will face each other in the last eight - the first time two Polish men have met at a Grand Slam. AND GET THIS: we are now guaranteed the first Polish men's semi-finalist at a Grand Slam.
15:00Jerzy Janowicz is the first Polish man to reach a Grand Slam quarter-final since Wojtek Fibak in 1980. Compatriot Lukasz Kubot is serving to make it two Polish men in the last eight right now...
14:55"@DavidFerrer87 back in QF @Wimbledon w/4-set win over #IvanDodig. 7th straight Grand Slam QF and will move to career-high No 3 #ATP rankings"
14:52Sabine Lisicki breaks back on Centre and trails 3-2 in the third against Serena. Jerzy Janowicz and Lukasz Kubot are 4-3 with a break in their respective matches against Melzer and Mannarino. Monica Puig leads 6-4, 5-5 against Sloane Stephens. Fernando Verdasco has a break in the first set against Kenny de Schepper.
14:48Excellent run by 19-year-old Laura Robson and she had her chances against Kaia Kanepi but couldn't quite get it done on the big points. Jo Durie remains Britain's last Grand Slam ladies' quarter-finalist - at Wimbledon, back in 1984.
14:46"I'm very, very happy, it was a tough match and I'm happy to get through this. I don't know (how they will celebrate in Estonia), maybe with some champagne?"
14:41Robson saves two match points but Kanepi bangs an ace down the T to bring up a third. Double fault! Here's a fourth - Robson finds the line with a booming forehand! Drama on No.1 Court. Another huge serve from KK and here's a fifth match point...surely this time...yes, she sends a forehand down the line to move into her second Wimbledon quarter-final.
14:38Sabine Lisicki misses four game points and is broken to trail 2-0 early in the third set against an unstoppable Serena Williams. Kaia Kanepi serving for victory over Laura Robson...
14:36Dodig? More like Do-didn't. Doesn't really work does it? Anyway, Daveeed Ferrer overcomes a sticky start to move into the quarter-finals where he'll get Delpo or Seppi.
14:33"Hingis watching Stephens vs Puig, wearing what appears to be 3-D sunglasses. She looks borderline scary"
14:29The winner of Melzer-Janowicz meets the winner of Kubot-Mannarino in the quarter-finals. Kubot leads 2-0 in the fifth.
14:28"Entertaining, intense duel between Jurgen Melzer -Jerzy Janowicz on Court 12. Likely semi at stake as they go into a 5th set"
14:25Serena Williams is right back on track against Sabine Lisicki, winning the second set 6-1 in 25 minutes and making precisely ZERO unforced errors.
14:21"I think this tournament is big surprise, like global...I'm just thinking about the next opponent. For me doesn't matter who is on the other side. I think it's a little bit more pressure then because everybody expecting that I win. That's something what it's not easy."
14:15Monica Puig takes the first set against Sloane Stephens in the battle of the up-and-comers on Court 18. David Ferrer has raced through the third set 6-1 to lead by two sets to one against Ivan Dodig. Two apiece in the second set between Laura Robson and Kaia Kanepi. SO MUCH TENNIS!
14:12Emphatic from the No.6 seed over the No.11 seed. Radwanska or Pironkova next for the Chinese superstar.
14:09Serena Williams is fighting back - as only she can. After dropping the first set 6-2, she is now 3-1 up in the second. Still some very angry muttering going on though. Li Na has been taken to three sets in her last two matches - doesn't look like happening today. She leads Italy's Roberta Vinci 6-2, 5-0.
14:07Into a deciding fifth set on Court 14 between Lukasz Kubot and Adrian Mannarino. Whoever wins will be lowest ranked Wimbledon quarter-finalist since Bernard Tomic in 2011.
13:59Robson belts a backhand wide and Kanepi has the first set, taking the breaker 8-6. Worried mumblings from the home crowd on No.1 Court.
13:58Serena Williams is having an off day - and Sabine Lisicki certainly isn't. The German takes the first set 6-2 against the five-time champion and overwhelming title favourite.
13:57Leading 5-2 in the tie-break, Laura Robson tightens up spectacularly and throws in a horrible double-fault along the way. She loses four straight points - but saves the set point with a brave forehand winner.
13:54Good question, Pablo. Juan Martin Del Potro took a spectacular tumble in his match on Saturday - and he was practising with some very heavy strapping on his left knee today. He is due on court to face Andreas Seppi after Robson-Kanepi.
13:53"HOW IS DELPO??"
13:51You're not wrong, Kim. Sabine Lisicki breaks for a 4-2 lead in the first against Serena Williams. Early indications that this could be the cracker we hoped it might be. Monica Puig is also up 4-2 against Sloane Stephens.
13:49"Serena looking a bit doubtful here"
13:45Jonny Marray's Wimbledream is over. He and Colin Fleming go out of the men's doubles in straight sets to No.6 seeds Robert Lindstedt and Daniel Nestor. Freddie Nielsen - Marray's partner when they won the title last year - went out in the second round with Grigor Dimitrov. Marray is still in the mixed with Heather Watson...
13:42Kanepi breaks back as Robson serves for the set and it's 5-5 there. David Ferrer snatches the second set on a tie-break and he is now level with Ivan Dodig. After dropping the first, Jerzy Janowicz is now two sets to one up on Jurgen Melzer.
13:41"In addition to Flipkens, 2 other #Wimbledon girls champs in Rd of 16: A Radwanska(2005) and Laura Robson(2008)"
13:37It's warming up into a humdinger on Centre, Lisicki going toe-to-toe with Serena. Robson is serving for the first set against Kanepi.
13:35"TREVOR MCDONALD!" goes a giddy cry in the Wimbledon bunker. Yes, the newsreader legend is out on No.1 Court watching Laura Robson take on Kaia Kanepi. Still on serve there, the Estonian leading 4-3.
13:25Lisicki has faced three break points - and saved them all against Serena. She leads 2-1 with serve. Robson and Kanepi also on serve at 2-2. Li Na has raced out to a 3-0 lead on Roberta Vinci on No.3 Court.
13:20"Very happy to see @FlipperKF reach first quarterfinal of grand slam! She so deserves it !!!! #proud"
13:16Last year's unlikely Wimbledon hero Jonny Marray - winner of the men's doubles with Freddie Nielsen - is playing with fellow Brit Colin Fleming this year, and the pair are in bother. Lindstedt (who was on the losing side in the 2012 final) and Nestor lead by two sets to love.
13:11Kirsten Flipkens is through to her first Grand Slam quarter-final - at the 19th attempt. The 27-year-old Belgian will play Kvitova tomorrow.
13:07Jerzy Janowicz and Jurgen Melzer have split the opening two sets on Court 12. Lukasz Kubot and Adrian Mannarino have done the same on on Court 14.
13:05Centre and No.1 Court action about to get under way with the ladies taking centre stage. Serena and Sabine Lisicki headline Centre while Britain's Laura Robson received a raucous reception as she walked onto No.1 with Kaia Kanepi.
13:01Kvitova serves out a very decent win over the dangerous Spaniard. She's through to her first Grand Slam quarter-final since last year's Wimbledon.
12:58Petra Kvitova is now a set and 5-2 up against Carla Suarez Navarro. Kvitova is the highest seed left in the bottom half of the draw. Should she serve this out, she'll get Flipkens or Pennetta.
12:52David Ferrer drops the first set against Ivan Dodig on the tie-break. Not sure any of us expected Daveeed to live up to his No.4 seeding - but Dodig is in the last 16 of a Grand Slam for the first time and he has had two of his opponents retire (Kohlschreiber, Sijsling) in his first three matches.
12:45I am here for your service, Joshua in gorgeous Malaysia. The four No.1s who were unable to make the WTA 40 Love Party were: Steffi Graf, Kim Clijsters, Venus Williams and Victoria Azarenka.
12:44"I can't even name all of the remaining four former no.1 who were not present at the WTA 40 Love Party. I can only think of Venus and Kim at the back of my mind. Help, anyone? Caroline?"
12:38Flavia Pennetta served for the first set twice...but Kirsten Flipkens won it on a tie-break. The Belgian No.20 seed is looking to reach a Grand Slam quarter-final for the first time.
12:31Carla Suarez Navarro is being supported by Conchita Martinez - the last Spanish woman to reach the fourth round of Wimbledon in 2001. Conchita Martinez's real name is Inmaculada Concepcion Martinez Bernat - according to the always reliable Wikipedia.
12:28Fist-pumping a-go-go on No.3 Court where Carla Suarez sticks a backhand in the net and Petra Kvitova clinches the first set on a tie-break. Ferrer and Dodig still on serve in the first set on No.2.
12:18Petra Kvitova serves for the first set against Carla Suarez Navarro - and is broken to love. Tie-break time on No.3 Court. Jurgen Melzer has the first set against Jerzy Janowicz. Another upset on that side of the draw? Why not...
12:15Hello Nena, lucky you getting Centre tickets. Tuesday is women's quarter-final day at Wimbledon, so I think we can guarantee Andy Murray won't be playing. Unless there is some kind of dramatic change in the weather and the Centre Court roof breaks. You never know...
12:14"Hi guys, I just got tickets for Centre Court tomorrow and i was wondering who's playing? I would live to see Andy but he's playing today. Will he play again tomorrow? Please get back to me."
12:11Yesterday, the great and good of women's tennis gathered at Wimbledon to celebrate the 40th anniversary of the WTA. Seventeen of the 21 No.1s since 1973 were present. You can watch all the red carpet interviews on the WTA website.
12:09"Amazing factoid from yesterday's WTA anniversary party: Navratilova played with or against everyone present save Wozniacki and Henin."
12:07The last time a British man and woman reached the Wimbledon quarter-finals - as Andy Murray and Laura Robson will try to do today - was in 1973 when Roger Taylor and Virginia Wade achieved the feat.
12:04While we wait for the inevitable fireworks, I feel I must again answer the question that continues to pile into my inbox: Why is Serena allowed to wear orange, erm, drawers? In it what is now known as the Golovin Rule (after she wore red pants a few years back), the predominantly white rule does not apply to, ahem, under-garments.
11:57What's happening early on? Not much. It's a cagey start to #ManicMonday: Ferrer and Dodig are on serve so are Kvitova and Suarez Navarro, so are Flipkens and Penetta, so are Kubot and Mannarino. BUT WAIT... Jurgen Melzer is serving with a 3-1 lead over Jerzy Janowicz.
11:48Shilin Xu is racing to victory over Britain's Pippa Horn in a singles' match on Court 4. Xu won the tremendously-named Chickeeduck Hong Kong Open Junior Tennis Championships 2012.
11:45Bit of a delay on No.2 Court where David Ferrer kept Ivan Dodig waiting. Juegos de la mente, as they probably don't say in Spain.
11:41We are go, go, go everywhere except Centre and No.1. The juniors actually started half an hour ago: that's the magic of youth, they don't take so long to get going in the morning.
11:35I'd like to congratulate Madhukar who's just emailed to ask if anyone is expecting Novak Djokovic to be saying Haas-ta La Vista later today (he plays Tommy Haas, you see).
11:30"In 2013 two @WTA players have 200+ Aces - Serena (292) and Lisicki (202). Today they meet in R16 @Wimbledon"
11:23Court 18 - which always seems to be dramarama central - hosts Monica Puig v Sloane Stephens: 19-year-old v 20-year-old, Puerto Rico v USA.
11:17And as always on #ManicMonday there is a wealth of magic tennis to be found around the grounds. Like Court 12, for example, where many people's semi-final tip Jerzy Janowicz is in action as well as 2007 finalist Marion Bartoli.
11:14Princess Laura Robson is first up on an intriguing No.1 Court line-up, facing Kaia Kanepi. Then it's Andreas Seppi v Juan Martin Del Potro and Bernard Tomic v Tomas Berdych. Seppi is on a run of seven straight five-set match wins, so if that ones goes the distance, I know who I'm backing.
11:04Serena opens play on Centre Court in what should be her first real test - against lawn lover Sabine Lisicki. Then it's Andy "Hopes of a Nation" Murray against Mikhail "Perennial Fourth-Rounder" Youzhny, before Novak Djokovic meets Tommy Haas.
11:00"Serena Williams has played more twice as many Grand Slam matches as any other player left in the draw..."
10:50Let's hope it's not too hot out there - we have a record-equalling NINE 30-somethings in singles action today. Haas, Melzer, Ferrer, Kubot and Youzhny on the men's, Serena, Li, Pennetta and Vinci are representing for the older lady. That is the most players over 30 in the fourth round at Wimbledon since 1975.
10:44Official weather report... Probably remaining dry with some sunny spells...Max temperature 20C (68F). Roof, take the day off, you've earned it.
