19:30With that, we really must go. It's been a pleasure as always. We need rest before a blockbuster men's semi-final day tomorrow. Britain's already holding its breath...
19:29"Venus, you're my favourite tennis player. Venus I love you," gushes a boy waiting for autographs. Sssshhh, Serena's right there dude!
19:26Having seen two match points go past, Serena goes for the jugular, causing Spears to duck for cover as a vicious volley comes her way. The Williams win 6-1, 6-1 and they're off with a wave for an awed Centre Court crowd.
19:23LOLs all round as someone in the crowd shouts out "come on Murray". Serena with a love game and they are a game away from the semi-finals. If I were Liezel Huber and Lisa Raymond, I'd be afraid. But that isn't really their style.
19:21Shouty as it was, hard to disagree with @Overitalrdy/ Sympathetic cheers for Kops-Jones and Spears as they get on the board in the second set at 4-1.
19:18Tweet from @Overitalrdy: VENUS AND SERENA IN A CLASS OF THEIR OWN.
19:14Spears manages to whack her own partner with an errant return. They're still smiling. Just about. They trail 3-0 in the second set.
19:13Tweet from @Annabel_Croft: What a Fantastic day here @LiveatWimbledon and what an amazing mens day tomorrow, can't wait
19:05V and S already a break up in the second. Serena's semi-final victim Victoria Azarenka is in mixed doubles action, partnering Max Mirnyi against Leander Paes and Elena Vesnina. On serve early in the first set.
19:01And they duly serve out to love to take the set. If they win this, they'll face Liezel Huber and Lisa Raymond in the semi-finals in another all-American match, which will be very, very tasty, I would imagine.
18:54Williams/Williams break again and they lead 5-1. It's a stroll in the Centre Court late sunshine...
18:50Venus trying to take the weight off her sister's shoulders by taking control of the rallies, and she's doing so pretty nicely thank you, the sisters leading 4-1.
18:43Serena hasn't served a double fault on Centre Court all day... until now. Doesn't matter though. She holds quite comfortably.
18:42Raquel Kops-Jones bravely crouching at the net in the face of the crunching Williams returns. Serena swipes one cross-court to set up break point, but Venus goes into the net and Abigail Spears hangs onto her serve.
18:33They're back now. Serena served 24 aces earlier... and looks like Venus wants in on the act as she starts with one of her own.
18:29Decent crowd out on Centre, as expected for the Williams sisters. What's going on though? Venus and Serena are both heading off court after the warm-up. Do they have to go to the toilet together?
18:12And if you think this will be one-sided, don't forget Kops-Jones and Spears are the No.10 seeds and their opponents are unseeded. Also, Venus and Serena Williams are four-time champions in the doubles. So there's also that.
18:09Great whooping and cheering on Centre as the crowd learns Venus and Serena Williams will be on shortly for their women's doubles quarter-final against Raquel Kops-Jones and Abigail Spears.
18:03Inglot double-faults to open the tiebreak and he and Robson soon find themselves 3-0 down. A double-fault from Robson puts them 4-1 down, and now she horribly misjudges an easy smash. Fleming/Hsieh leading 5-1 at the changeover, and now 6-1. Inglot saves two of the match points with successive aces, but Fleming closes it out with a big serve out wide. Fleming and Hsieh through to the quarter-finals to face Zimonjic/Srebotnik.
17:58And we're into another tiebreak in the Fleming/Hsieh v Robson/Inglot blockbuster.
17:53Fleming/Hsieh serving at 5-4 down, and they lost the first point when Robson sends up an inch-perfect lob. Fleming with a volley into the net and it's set point Robson/Inglot. Big serve saves the day.
17:49Mansour Bahrami out on Court 12 up to his old tricks along with Henri Leconte. He has already caught the ball in his pocket, given someone in the crowd a bottle of water and served with five balls in his hand. Lovely.
17:44Robson/Inglot have to save a break point but they're still on serve in the second set against Fleming/Hsieh, but a set down.
17:23Some sensational photos of today's action in the gallery. The one of Serena leaping for joy is amazing.
17:13Fleming and Hsieh out to a 4-1 lead courtesy of some solid serving, but Robson's serve gets her team back to 4-2 as they switch sides. Fleming booms down an ace to move to three set points. And then he finds the dipping return that forces Inglot to net. First set to Britain/Taiwan.
17:12TIEBREAK ON CENTRE COURT! Are you feeling the mixed doubles magic?
17:05If you missed it, the Bryan brothers earlier edged out fellow Americans Lipsky/Ram in five sets to reach the men's doubles semi-finals where they'll face Britain's Jonny Marray and his Danish partner Freddie Nielsen. No.5 seeds Robert Lindstedt and Horia Tecau will face No.10 seeds Jurgen Melzer and Philipp Petzschner in the other semi-final.
17:03All square in the big mixed clash on Centre - 5-5, with Fleming/Hsieh serving
16:52Wonder if Martina Navratilova has ever played on Court 15 before? She has now, and it seems she is STILL not over her 1994 defeat by Conchita Martinez in the women's singles final. She and Jana Novotna currently thrashing Martinez and Nathalie Tauziat 6-0, 4-1. The benches are packed...
16:43Vinci/Errani may be out but fellow Italians Francesca Schiavone and Flavia Pennetta are still going in the women's doubles, beating Llagostera Vives/Martinez Sanchez 6-2, 6-7, 6-4. Sorry for not typing those names out. But they're out now. Time to move on. The Italians face... Hlavackova/Hradecka in the semi-finals. Top seeds Lisa Raymond and Liezel Huber face the winner of a later match between Williams/Williams and Spears/Kops-Jones. Americans everywhere you look...
16:27Next up on Centre Court, and recalling the glory days of 1987 mixed doubles champions Jeremy Bates and Jo Durie, we have Dominic Inglot and Laura Robson, the British pair up against another Brit, Colin Fleming, and his Taiwanese partner Su-Wei Hsieh. We literally can't lose here! When I say we, I mean Great Britain.
16:23Serena is through to her seventh Wimbledon final - although she seemed quite surprised about that fact when she was just reminded of it in that interview. She also seems to have forgotten that she played Radwanska in the quarter-finals here in 2008. Serena has won both their previous meetings in straight sets, although both were four years ago.
16:22"She's doing unbelievable. She's playing so great, wow, she's going to get every ball back so I've got to look forward to that. Regardless, I'm so happy."
16:19"I'm excited. I've been working so hard and I really wanted it. Victoria is a great player and she was playing really well. I got a little tight and I was looking a little too much into the future. I was getting excited, thinking 'I'm so close'."
16:18Williams leaping around, almost Venus-style but maybe not quite as graceful as her older sister. A stunning performance, but huge credit to Azarenka. Very enjoyable tussle, especially in the second set.
16:16Azarenka pushes a backhand into the net and it's the first mini-break of a gripping tiebreak. Williams with a second match point. ACE! Sensational. Broke the Wimbledon record on the last point with her 24th ace.
16:08Azarenka tries challenging a Williams ace. Can't blame her, but it is in. Her 22nd. But we're still on serve, Serena hopping about as she misses a return for Aza to lead 3-2. They change over at 3-3 after a typically dominant baseline rally by Serena. Great match this. Serena right onto her haunches as she gets just about enough dip on a forehand for it to land on the edge of the line. A return long and Aza levels at 4-4, before the Belarusian is screaming "come on" with a whipping, zipping forehand. Such quality. 23rd ace from Serena and there's not a sniff of a mini-break at 5-5. Azarenka into the top of the net now and Serena has match point. Not anymore. Williams drop shots then lobs wildly over the baseline. She leans on her racket in despair. It's 6-6 and they change ends.
16:05This is phenomenal serving by Serena, who has now served 80 aces in the tournament. Make that 81, as she moves to 40-0. Makes it all the more impressive that Azarenka is still in this. Azarenka super pumped up as she pegs her back to 40-30 and guess what? Yup, ace No.21. The record here is 23. Tiebreak...
16:02Azarenka gets in on the ace act - with her first of the match. The Belarusian powers a backhand down the line to move to 40-0 and an unreturnable serve makes it a love service game.
16:0035 winners to 9 now, in Serena's favour. Ace No. 18 for Williams and she holds to 15. Azarenka doing so well to hang onto Serena's coat-tails.
15:54Get it on the highlights reel. Serena completely out of the rally, totally off balance, but she somehow finds a viciously dipping forehand pass. It's an otherwise comfortable game for Azarenka though, her serve firing nicely.
15:51Serena gets to 30-0 in double-quick time. Aza tries to slow everything down and the umpire has to stop Serena mid-service motion because Aza isn't ready. Holds to 15. A welcome, easy game for Williams after the aberration in her last service game.
15:43Serena leaps in frustration as she slaps the net with a return off a second serve. Would have given her break points. Instead it's 30-30, but Azarenka looks at the court accusingly as she then balloons one long. Break point but she finds a big serve down the middle and Williams nets. Unbelievable 22-stroke rally from the baseline and Serena wins it when Aza nets. Brutal hitting from both. It's break point again. Missed first serve but Williams can't take advantage and two first serves get her out of trouble. Is the momentum shifting?
15:38Hold on. Serena frames a forehand wildly and Azarenka has a real chance at 15-30. Ace. I mean, you could have put your house on it. That's her 14th ace. Incredible. Serena into the net as Aza steps on the power and she has break point for the first time today... You know it. ACE out wide. Now Serena goes long on a short forehand. Aza with a second break point. First serve into the net... Surely she has to take this one... She does! Williams fails to handle the pace off the return and frames a backhand.
15:37"My plan was playing aggressive tennis and make the points, but she moved very well and makes not so many mistakes, so it was really tough to play really constant, you know, and make winners against her today. But I try to fighting until the last point. I mean, yeah, what can I say? I mean, she played a very, very good match."
15:33Williams wallops a backhand return onto the sideline and calmly strolls to the other side of the court. Just another day at the office. Azarenka holds to 30, but every point is a battle.
15:29Ha. Williams loses the first point and then misses the first serve on the next point. Her response? A second serve ace down the middle. The Centre Court crowd is just in awe of this performance right now. But wait. She kicks her foot in despair as she nets a forehand and crisis, she only has one game point... Well, maybe it is a crisis. She goes wide with a backhand on a point she's dominating. Deuce. Ace. Ace. You know how this goes.
15:28Tweet from @0try: Oh #Serena scared me there with that scream! but what a competitor!
15:24Eek. Another double fault from Azarenka to open the game. Nasty habit. A squeal from the Belarusian as she smacks the top of the net with a backhand and she faces two break points. "Come on," Serena yells, finally letting out a bit of emotion as she crunches a brilliant return cross-court. Venus applauds. As do we all.
15:19Wag in the crowd with an Azarenka hoot as they change ends. Maybe they fired her up. The Belarusian steps inside the baseline to take control of the first point - and win it. Azarenka gets to 30-30 with a lovely backhand pass. How will Serena respond? With an ace, of course. What's this? An error from Williams and she faces a rare bit of bother at deuce. Ace. It's like she can just deliver them on command.
15:16Serena lost four points on serve in that set, and one behind her first serve. She hit 20 winners, to Azarenka's 4. Azarenka opens the second set with a double fault and is in a bit of trouble at 15-30 but she's still fist-pumping away and holds to 30.
15:12Unstoppable. Williams moves to two set points. She is held up when Azarenka pounds a backhand winner, but then the Belarusian smacks the net with a return. That is the ninth set in a row Williams has won against Azarenka.
15:10This is an ominously good performance from Williams, whose probing returns get her to two break points. She only needs one, chasing down a drop shot and whipping it down the line. A clenched fist is the first show of any emotion from Williams so far.
15:04Serena looking so calm and focused. Not a peep out of her so far. A brutal love game there.
14:58Venus sitting next to a young kid and playfully poking his cheek. Both Serena and Richard Williams credited Venus's words for wisdom for the younger sister's improved performance in the last round. Aza starts the game with a double fault and now Serena finds an impossible angle on a backhand. Danger time at 15-30 but now Aza's clenching her fist as Serena goes wide. Far too much weight on that backhand from Serena, pouncing on a second serve. Couple of deuces in the game, but Azarenka hangs on.
14:55Serena puts a smash straight back at Aza, but there's enough power on it and she gets away with it. She holds and this semi-final is warming up nicely.
14:50Brilliant defensive forehand from Serena, whipping it cross-court to get back to 15-15. Serena not having much luck on the Aza serve though, the Belarusian keeping it nice and deep... At 40-15, Serena turns her hips and hammers a return onto the baseline. There was FURY in that shot. But then she hooks a forehand well long.
14:48Boom. Ace No.2 from Serena. And there's No.3. Ha! And there's No.4. Can she get the full house? She can't, but Azarenka goes wide and it's a love game.
14:45Azarenka was in cropped leggings the other day, but in a nod to the Great British sunshine, she has shed those today. Confident opening game from the world No.2, serving well and dominating the baseline rallies... Ah, just as I type that she double-faults to go to 40-15. Serena whacks a return in the net on the next point though.
14:41Big return from Aza off the Serena second serve and she gets to 15-30, but here's Serena with a thumping backhand winner. Already a completely different match to the first - plenty of power. Wow. Supreme forehand down the line from Serena and she wraps up the opening game.
14:39Serena wearing her cropped double-breasted jacket to warm up in. Love that. The American has a 7-1 record against Azarenka, the most recent win in Madrid on clay. Their only meeting on grass came here in 2009 when Serena won 6-2, 6-3 in the quarter-finals. Serena to serve first...
14:32Tweet from tennis writer @BenRothenberg Radwanska is 0-2 against Serena Williams, 3-11 against Azarenka. Whom do you think she would rather play?
14:30Tweet from @martins_92 In moments like these, I'm so proud to be Polish! It's all thanks to you Agnieszka!
14:26"I think we both were a bit nervous in the beginning. It's a semi-final so you want to try your best but sometimes you want it too much. After a couple of games I relaxed a little bit. We were very good friends but on court you're trying your best and both fighting for the final. One match to go and I'm really going to try my best. I think this is a dream from when I was a kid. I've been playing tennis almost 18 years and of course everybody dreams to play a Grand Slam final."
14:24Well, Radwanska barely managing a smile but I'm sure she's happy on the inside. Kerber turns and waves to the crowd as she walks off in disappointment. Bit of a disappointing match in the end... Radwanska only the second Polish woman to reach a Grand Slam final and first since 1939.
14:18Radwanska thinks she has an ace. Kerber challenges - and she's right! She smiles in surprise. Big roar from the crowd who want this semi-final to go a bit longer. Radwanska back to 15-15. Kerber long with a return - disappointing. 30-15 now for Radwanska and Kerber shanks a forehand disastrously wide. Two match points for Radwanska. Kerber WIDE. Radwanska leaping on her toes as she watches the ball drop in the trams.
14:16Kerber still going for her shots, and swings a forehand onto the baseline. Not sure how, not sure she knows, but hey... Big serve out wide which not even Radwanska can scramble back. Radwanska about to serve for a place in the Wimbledon final. Will she crack? I doubt it...
14:12The fat lady is preparing to sing - in German. No openings for Kerber there and she'll have to serve to stay in the match.
14:08Must-win game for Kerber and she moves out to 40-15... before being pegged right back to deuce. Huh. An error from Radwanska. She probably meant to do that, all part of the brilliant masterplan.
13:59Kerber canters up to net and pummels a forehand cross-court. Big "come on" there. It's 30-30 and SURELY SHE HAS WON THIS POINT - NOOOOO! Kerber has another big forehand to put away and Radwanska runs full pelt along the baseline and pings it back for a winner. Lordy, what on earth is this? Moonballing??! It's like the ghost of Conchita Martinez* on Centre. Radwanska eventually goes long - a very rare error - and Kerber goes on to earn break point. Radwanska unmoved though and holds. (*Conchita Martinez is not dead. She's actually playing vets doubles on Court 15)
13:56I'm watching my prediction of a Kerber-Serena final go up in smoke. I'll stay strong. Kerber broken again, Radwanska proving far too tactically astute for the German at the moment.
13:53Backatcha. And just like that, Radwanska held serve.
13:50Radwanska slicing, dicing... and then Kerber swipes at the ball dramatically and whacks the ball out - like being trapped lbw by Shane Warne. That's better. A beautifully-timed backhand down the line and Kerber holds on.
13:48Kerber clearly trying to take command, and up the power, but too many errors in this game. Radwanska holds to 15.
13:44Radwanska straight off court for a bathroom break after winning that set. From 3-1 down, she won five straight games. Kerber starts the second set in positive fashion with two booming baseline winners. She holds to love emphatically.
13:40Radwanska continuing to weave her webs, hoping to ensnare Kerber. But the German moves out to 15-30 after some incredible defence. Radwanska responds, hitting a forehand from on her knees to win the point. She serves an ace out wide to clinch the set.
13:35Double! Kerber falls to 15-30 with her first of the match but then responds with a wickedly angled backhand winner. Radwanska to break point though after a loooong baseline rally and she takes it when Kerber pushes for too much and nets.
13:31Radwanska shrugs off the disappointment of seeing a woefully weak second serve being given the treatment by pelting a forehand winner down the line. Radwanska has to save another break point - getting her first serve in seems to be key to her winning the points - but comes through.
13:28Maybe that will settle the nerves, Radwanska's drop shot clips the net and dribbles over, leaving Kerber no chance. Radwanska earns break point with a pass down the line and then Kerber is on her knees to net a forehand. All square.
13:23Radwanska taking gulps of air between points, while Kerber is skipping about Centre Court like she owns it. The Pole has two game points but nets a simple forehand, and is lucky to see Kerber overhit a return on the second.
13:20Kerber definitely winning the battle of nerves, the German stepping in to confidently swat away a forehand winner. Leading 40-15, she powers a backhand down the line, leaving Radwanska completely off-balance.
13:18This isn't power tennis by any means. At 30-30, there's some loopy shots from both sides before Kerber steps up the pace to win the point. That's a first break point and Radwanska plays an awkward-looking drop shot that drops wide.
13:15Kerber responds with a love game. Decent start eh?
13:12That was simple enough. Radwanska begins her first ever Grand Slam semi-final with a love game. Kerber reached the U.S. Open semi-finals last year. At her previous Grand Slam, she lost to Laura Robson here in the first round.
13:11Alison Lang in the chair and "time" is called. Cloudy skies with pockets of blue. Radwanska to serve first.
13:05Aga Radwanska and Angie Kerber are now knocking up on Centre Court. Both looking quite relaxed on the occasion of their first Wimbledon semi-final.
12:53The winning streak is over. After 26 matches unbeaten (excluding Fed Cup), Sara Errani and Roberta Vinci are beaten 6-3, 6-4 by Andrea Hlavackova and Lucie Hradecka.
12:35Less than half an hour until Aga Radwanska and Angelique Kerber step onto Centre Court for their semi-final. The last Polish woman to reach a Grand Slam final was Jadwiga Jedrzejowska, who made the final at Wimbledon (1937), the U.S. Open (1937) and the French Open (1939). She lost all three.
12:32Oof, no need for any dying @Rash_x. Murray has been out on Court 9 having a hit with Dani Vallverdu, a member of his coaching team, and the crowds duly flocked. Keep checking our our Facebook page for the best pictures.
12:23Tweet from @Rash_x: Watching @andy_murray practise, I think I just died @Wimbledon
12:15Doubles quarter-final news: on No.2 Court where Andrea Hlavackova and Lucie Hradecka are a set up against French Open champions Sara Errani and Roberta Vinci, who are on a 26-match winning streak (discounting Fed Cup). On No.3 Court, Lindstedt/Tecau have taken the first set against Bracciali/Knowle. Horia Tecau has just found out he will be carrying the Romanian flag at the Olympics.
12:01Another dazzling fact? Angelique Kerber is aiming to become the first German woman to reach a Grand Slam singles final since Wimbledon 1999. And you don't get any prizes for guessing who that was.
11:53Other things that happened on July 5: Martina Hingis won her first singles title in 1997. Serena Williams won the mixed doubles in 1998 with with Max Mirnyi when she was 16. Laura Robson won the junior title in 2008. Jeremy Bates and Jo Durie won the mixed in 1987 to become the first Brits to win the title since 1936. Truly a historic date in Wimbledon's history.
11:51July 5. The day in 1975 when Arthur Ashe became the only black man to win Wimbledon by outmanoeuvring the hard-hitting Jimmy Connors. The day in 1992 when Andre Agassi took his first step to greatness by winning on his least favourite surface. But also the day in 1980 when Bjorn Borg and John McEnroe played out what was previously the undisputed greatest match in history. Surely it still contains the greatest ever tiebreak. McEnroe had already saved two match points and he saved five more in the tiebreak to win it 18-16. Would Borg crack? Would he heck. The Iceman won the fifth set 8-6 for the last of his five Wimbledon titles.
11:47Almost forgot On This Day, the live blog feature that's rocking the nation...
11:42I will dazzle you (maybe) with more facts as we go... But play is go, go, go on the outside courts and I'm thinking Croatian prospect Ana Konjuh is not a fan of early starts. She has just won her first game after losing the first seven against Anett Kontaveit of Estonia in a girls' singles quarter-final. Bad news also for Sabina Sharipova, who trails 5-3 to Elina Svitolina. Boys' No.1 seed and defending champ Luke Saville not having it all his own way on Court 14 where he and Nikola Milojevic are on serve at the sharp end of the first set.
11:38How about this: Serena has 13 Grand Slam titles, the other three semi-finalists have one between them.
11:35Semi-final No.2 sees four-time champion Serena Williams up against world No.2 Victoria Azarenka in another mouthwatering clash. If the Belarusian wins, she will reclaim the No.1 ranking. If she loses, she will still take it if Radwanska doesn't win the title.
11:29But today is very much about the ladies. Coming up from 1pm, two genuinely fascinating semi-finals. The first pits fast-rising German Angelique Kerber against world No.3 Aga Radwanska. Both are in their first Wimbledon semi-final, they have a 2-2 head-to-head record, and it's almost impossible to call.
11:19Not that we in Britain are getting carried away but Murray takes a 5-1 record against Jo-Wilfried Tsonga into their semi-final. Yes, we're completely getting carried away. Just no-one tell us about the two fellas in the other semi-final.
11:13Plenty of reaction to yesterday's men's quarter-finals on wimbledon.com. Murray was in particularly philosophical mood after beating David Ferrer in four gloriously attritional sets on Centre Court. He was particularly revealing when he started talking about LeBron James. "There's a lot of people out there that didn't want him to win. There's a lot of people that said he would never win. There's a lot of people who said he never played his best in finals ... Sometimes it takes guys a bit longer than others."
11:05Andymonium is in full effect in Great Britain. Seventy-six years and counting. For light relief though, look no further than Joey Chestnut, winner of the annual Fourth of July Hot Dog Eating Contest. He ate 68 in 10 minutes, winning by a whopping 16. Sonya Thomas managed 45 hot dogs to win the women's title, but still got the same prize money of $10,000. What does Gilles Simon say about all this?
11:02Yes, on the 10th day, the sun finally decided to make an appearance - although with the caveat that there is still a 40% chance of a shower.
11:00Excuse me if my typing's a bit funny. It's just that THE SUN'S IN MY EYES.
We want to hear from you! Tweet us @wimbledon or email email@example.com
