0520: That's your lot for day 10, but there's good news... it's already day 11! We have the remaining two men's quarter-finals to come, with Juan Martin del Potro and Marin Cilic on after two doubles matches at around 1900 BST, followed by Rafael Nadal v Fernando Gonzalez from midnight (UK time). Rafa v Gonzo - you know that's going to be good. Meet you back here. Night/morning.

0510: This is one heavyweight tie-break - both men matching each other on serve all the way to 6-5 and set point for Soderling, with the crowd going bananas... but the Swede plays a shocker of a return from a second serve. Federer holds twice, obviously, and Soderling finally folds with a forehand into the tramlines on the first match point. A stunning match.

BBC 5 live's Alastair Eykyn on Twitter: "If you're wondering why no DL tweets recently, his computer's exploded. Amazing it's taken this long really. Fed closing in again."

0508: "Wonder if Joanna has No Regrets about going to bed now? A terrific match and Federer at his very best. Still cursing the Swede that i've been kept up another hour mind... "
Matt, Blackburn, via text

0501: Federer holds, Neil Diamond belts out Sweet Caroline over the PA, half the crowd join in (I think there may have been some drinking) - can Soderling force another tie-break? Federer chases down a forehand on the run and whips it past Soderling for 30-30, but Super Rob comes up with a huge forehand and raking backhand to hold. Magnificent stuff.

0455: With the exit door inching open, Soderling shows no sign of nerves as he blasts his way through a love game to level things up at 5-5. He can't take it to a fifth, can he? I'll run out of tea bags.

0450: Good stuff from Soderling as he holds to 15 and Federer is starting to look a bit narked. He probably feels he should just be tucking into his main course having seen off a starter somewhere in Manhttan. Instead, he's 4-4 in the fourth.

0445: Federer has another half-chance on the Soderling serve but the Swede is pummelling away on the forehand and, thanks in part to another umpire overrule, he holds to make it 3-3 in the fourth set.

0436: At 0-30 and again at deuce, Federer fails to come up with the goods and allows Soderling to hold on for 2-2.

0431: A little bit of drama as Soderling gets to 0-30 and correctly goes to Hawkeye which overrules an ace for Federer. The Swiss then hits a cross-court forehand which is called 'out', the umpire overrules as 'in', and Hawkeye confirms he was correct. A confused Soderling feels the point should be replayed but he's out of luck and Federer holds to lead 2-1 in the fourth.

0427: Well, who'd have thought it? Super Rob battles back from 5-2 down in the tie-break to win it. Still, life moves on and after Federer holds easily at the start of the fourth, Soderling is under pressure at 30-30 but comes through.

0421: What a tie-break - Soderling takes it from 5-2 down. Federer draws an error on the first point, smacks down two huge serves, and forces another mistake for 4-0. Soderling has a sniff when he gets back to 4-2 down and goes for a forehand but it's just wide. Soderling stays in it with two good serves and gets back to 5-5 with a forehand winner, before Federer is way out of position and nets to trail 6-5. Set point for Soderling... but Federer returns a first serve with an angled return and runs in to put away the forehand. Soderling wins a battle of the forehands for 7-6 and set point two... and he takes it with a great return and several battering forehands. Incredible. That gets a shock graphic.

0412: Soderling is serving well now and guarantees himself a tie-break but Federer holds just as easily, with one flicked backhand a masterstroke, and he takes us to a tie-break with an arrowed forehand winner. I know who my money's on...

0407: After an impressive hold from Soderling to lead 5-4, Federer opnes with a smash into the tramlines. Nerves? Er, no. He powers through the next four points and cracks ace number 20 to make it 5-5.

0401: A couple of regulation service holds take us to 4-4 and the pressure is mounting on Soderling's service games. Rog looks menacing.

0355: What's this? Soderling plays a blinder of a return to get to 15-40 and two breaks points... but this time it's Federer who comes up with the big serves when under pressure and it's 3-3.

0351: Federer continues to look imperious on serve and Soderling is doing a bit better now, snapping away a backhand volley to lead 3-2 on serve.

0345: I think he's getting better. Federer serves his way to 40-0 and then reaches for a wide one and hooks a forehand down the line. Here's Novak Djokovic on facing Federer next... "We don't need to talk a lot about his records in US Open, we all know his style of the game. I have been playing against him many, many times and a lot of different kind of surfaces. There is no secrets in each other's game, so I just - it's a matter of good day."

0341: Federer plays a huge forehand winner for 15-30 and follows it up with a pass that's so good it makes me laugh. Two break points... but Soderling sees them off with his serve and takes the game with an ace.

0336: Federer calmly sticks away his 10th ace of the night and strolls towards his chair leading 12-3, or 6-0 6-3 if you're a stickler for tradition.

0331: Joanna - I'm disappointed in you; Daz and Matt - you've restored my faith. Soderling double-faults and smashes his racquet in frustration, much to the delight of the locals. It's pretty tough going out there at the moment as Federer is in sensational form, hooking one cracker of a forehand down the line, and Super Rob does well to save a break point -but Rog will serve for a two-set lead.

0328: "Not exactly a band, but its safe to say this isn't going to be a Fairytale in New York for Soderling. Might be for Federer come Sunday mind on this performance>"
From Matt, Blackburn, via text

0327: "Band name comm. Sodering makes Fed. RUSH, but WHAM! returns a winner TAKE THAT. just WHO can live with him."
From Daz in wales via text

0327: "Wish Robin could at least make a match, but with 1st set bagel (and my support cursing Oudin) I am going to bed and abandoning him to his fate."
From Joanna via text

0327: Federer rattles through another service game and again gets to 15-40 on the Soderling serve. Again, the Swede battles back to deuce but it only delays the inevitable and Federer converts his third break point for a 4-2 lead. And as I write, he plays a ridiculous half-volley for another love hold and 5-2. Fantastic stuff from the world number one at the moment. Maybe Cotton Eye Joe can raise Robin's spirits...

0316: Soderling is facing disaster at 15-40 and two break points down but credit to the big Swede, he serves his way out trouble and levels at 2-2.

0312: He's too quick for me - Federer holds to lead by a set and 2-1.

0309: Wham! Soderling saves and we have a match on our hands everyone.

0307: Soderling gets his now traditional early break point... and Federer smacks an ace. Brilliant. He holds for 7-0. I have now mentioned Gavin Rossdale's band Bush, and inadvertently his wife Gwen Stefani's band No Doubt in the last two entries. I may subtly add more band names in future entries until we get more of a contest.

0248: "I take it all back! Lets just give him the trophy now."
Kevin, Norwich, via text

0303: Federer wraps up the first set 6-0 in 25 minutes and it's been an exemplary display from the champion, no doubt, but it's hard to say whether Soderling could be doing any more. One bright spot is the unexpected arrival of the bagel graphic.

0258: Gavin Rossdale from Bush looks on as he sits alongside Mirka in the Federer box. Do Bush still make music? He seems to spend most of his time watching Roger demolish people and win Grand Slams. Speaking of which, Federer leads 5-0.

0255: Soderling does manage one nice lob, I'll give him that, but Federer is all over him and breaks again for 4-0.

0248: Federer swiftly holds to love and he leads 3-0.

0248: "Well my hope for Robin is simply this...'Nobody beats Vitas Gerulaitis 17 times in a row.'"
Kevin, Norwich, via text

0247: ...and Federer breaks at the first opportunity, to love. Has Super Rob already missed his chance? Again, apologies for any arrow bias but I haven't got a Swedish one.

0243: Federer, in his now customary evening attire of all black, kicks things off with an interesting service hold. After letting Soderling get back to deuce, the Swiss saves two break points, one with a big serve and one with an ace. Federer also double-faults before coming through, not entirely convincingly.

0238: "Re 0226 The point has been made previously but didn't Soderling do something similar at the French Open by taking out the red hot favourite."
From Kevin, Crawley, via text

0226: OK, hold tight because it's nearly time for Robin Soderling to set about clawing back the 11-0 career deficit he has against Roger Federer. Do you think Robin leapt out of bed this morning and thought, "Yes! Today's the day!" Let's hope so.

0216: In the end, it was a bit of a damp squib. From the moment the match began in a barely half-empty stadium it felt like an anti-climax for two teenagers playing their biggest ever match. Oudin basically ran out of gas and Wozniacki showed why she's a top-tenner with a solid display. The Dane will be a strong favourite to make the final now as she plays unseeded Belgian Yanina Wickmayer in the last four. In place of a Danish arrow, I give you... the sun!

0207: Oudin is still getting chances and has another at 30-30 but Wozniacki forces an error with a fine cross-court forehand, and the American then wallops one in the net to put the Dane a set and 5-2 up. This is a long way back, even for Oudin.

BBC 5 live's Alastair Eykyn on Twitter: "Ashe Stadium rammed now - bloke in beige baseball cap eating his own bodyweight in pizza a few rows away from comm box."

Serena Williams on Twitter: "Jut finished dinner. Sleeply!!!!"

0203: After a nailbiting previous game, Oudin understandably falls flat on serve and is quickly 0-40 and three break points down... and a net cord goes against the American to put Wozniacki a set and 4-2 up. And it looks like Diego Maradona could be looking for a new job after his Argentina side just lost 1-0 to Paraguay. I think he'd be an interesting addition to Team Murray.

0157: Wozniacki appears to be wobbling when she opens with a double-fault and more so at deuce when, after a great serve, she hammers a mid-court sitter into the net for break point... but Oudin sends a backhand into the tramlines. The American then plays a drop shot which just about comes off for a second break point... but she sends a forehand long and Wozniacki holds for 3-2. I went on holiday to Denmark when I was 13, lovely place. My dad was charged £5 for a glass of wine though and that took the shine off his mood for two weeks.

0146: That's a bit more like it from Oudin as she holds easily for 2-2.

0143: "Oudin's had 5 service games. In all 4 during the first set she faced break points and in the first me the second set she was taken to deuce! She' s making this far too easy for Wozniacki so far. Hard to believe she's knocked out Dementieva, Jankovic and Petrova so far. That said, come on Caroline!"
Matt, Blackburn, via text

0142: "Kinda wishing the US Open was held in Europe so I could get some sleep b4 dawn everyday but is guessing that it would kinda defeat the point of it being called the US OPEN."
From anon via text

0141: You know who Wozniacki reminds me of? Andy Murray. She varies her pace a bit, gets everything in and draws mistakes from her opponent. The problem with that, as we've seen, comes when the opponent starts making winners. There are signs of that from Oudin when a forehand and a backhand take her to break point, but the American then misses with a big forehand and Wozniacki hangs on with a net cord for 2-1. It's getting closer though.

0135: Oudin is still struggling but battles through a service game from deuce with a thumping forehand drive volley and a fierce backhand to level at 1-1. And good shout, Katie. We have two doubles matches from 1600 BST before Del Potro v Cilic at, I'm guessing, around 1900 BST, with Nadal v Gonzalez at midnight (UK time). I will be right here for that and can't wait.

0132: "Any news on the order of play for tomorrow? I need to plan how much coffee i'll need to stay awake for Rafa."
From Katie in Leeds via text on 81111

0128: I must apologise for the American bias in terms of arrow graphics but I don't have a Danish one to reflect the soaring fortunes of Wozniacki. She looks very calm as she serves out to move 1-0 clear in the second set, while Oudin veers between a woeful smash and a fizzing pass, with a bit of Wilanderesque moonballing thrown in for good measure.

0121: Wozniacki is doing a good job of keeping Oudin moving and not giving her any pace, but the Dane plays an edgy volley that floats long for 30-30. Oudin then nets for the second time in the game and it's set point.... but Wozniacki goes long. Another forehand into the net from the American makes it set point number two... and Oudin saves it with a decent backhand down the line.The local girl just cannot get any rhythm though and sends a forehand long for set point three... and then sprays a wild backhand out wide to give Wozniacki the set 6-2.

0113: With the set seemingly gone, Oudin unloads on a couple of forehands and earns two break points at 15-40... and Wozniacki double-faults on the second. The Dane's first blip of the night.

0109: Wozniacki looks like a top-10 player against a rank outsider right now, which technically speaking is correct. Oudin nets on break point and trails 5-1. The Oudin supporters have T-shirts with the word 'Believe' emblazoned across the front. I remember manager Alan Pardew wearing something similar when West Ham played Crystal Palace in the play-off final a few years ago. West Ham lost to a Neil Shipperley shinner, and the Oudin camp are having a similarly underwhelming night so far.

0104: Wozniacki opens with a great point - she doesn't hit the ball that hard but is putting it in the corners at the moment and getting Oudin running. She's also serving very well and holds to 15 for 4-1, with Oudin managing one forehand winner down the line.

0101: Oudin thumps one over the baseline and faces another break point... but this time Wozniacki lets her off the hook by netting a forehand. A couple of solid forehand put-aways (?) give Oudin the game and get the crowd going - 3-1 Wozniacki. And as for crying, I'm all for it before, after and preferably during matches. The more drama the better.

andyram99 on Twitter: "Saw some old RFed videos. What's the verdict abt crying - win or lose at the end of big matches?"

0055: Apologies for the delay, computer briefly says 'No.' Oudin looks nervous and makes two errors to fall 0-40 down before double-faulting to give Wozniacki the break, and the Dane then serves out to love for 3-0.

BBC 5 live's David Law on Twitter: "First ball about to be hit and there are thousands and thousands of people trying to get in. What are the USTA doing????????? If I was a paying punter, I'd be demanding a refund for this treatment. And it ruins the atmos of what should be a classic. Pathetic."

0048: Wozniacki takes the opening game on serve with a move to the net and nice low volley, having thrown in a double-fault on the point before.

0043: Thanks Joanna, you just about saved yourself there. You can get updates on 5 live and full commentary later in the week. We're nearly ready to go, Wozniacki to serve first...

0040: "Why are all the best matches on past 12, with no radio coverage!?! (Not that I don't love your commentary, Piers)."
From tired Joanna, rooting for Oudin, via text on 81111

0040: "Cammy in Sunny Motherwell (well it was earlier) going to bed now but waiting for Federer to win in straight sets to get Yankee bet correct at the US Open !! I already called SERENA 2 PENNETTA 0, RAFA 3 MONFILS 1 + NOLE 3 VERDASCO 1. Hardly Derren Brown but hey ho. Go Roger."
From anon via text

0037: Melanie Oudin walks out onto a pretty empty and dank Arthur Ashe Stadium for her first night match. The fans are coming in so it should liven up soon enough. Wozniacki is out there too, still in the Stella McCartney outfit. The Blackeyed Peas' Tonight's Going to be a Good Night plays on the PA. Desperate stuff.

0030: "It was kind of hard to concentrate: I was listening to the songs on the changeovers, like, 'OK, I could've done a better fill there,'" says Mike Bryan after he and Bob lose in the doubles. The pair had planned to release their new band's first album this week but it fell through.

0021: If you wish to pass on your wisdom, which let's face it I could do with, send a text to 81111 or a message to Twitter.

0019: "We have a delay until 0035 BST following the lengthy but apparently rather disappointing Djokovic-Verdasco match. It's a bit blustery and overcast in New York from what I can see.

0012: As we await the arrival of Oudin and Wozniacki on Arthur Ashe Stadium, let's hear what Leander Paes has to say about reaching both the doubles and mixed doubles finals for the second year running: "I love this city, I lived here for three and a half years and I love playing here. The energy of New York is what turns me on. My results in the last four years, getting to a slam final every year is something that's really wonderful. Got a little bit of work still to do tomorrow and day after and that's where my focus is now, to use the energy of New York City when we get on court."

0001: So what are the prospects for tonight? It's fair to say the first match is the harder to call, with Wozniacki playing Oudin for the first time. Actually, pretty much everyone has been playing Oudin for the first time and it hasn't done them much good. The 17-year-old is ranked 62 places lower at 70 in the world but is not short of support, belief or momentum. As for the second match, Federer has a 11-0 record against Soderling. Robin will do well to get a set.

2355: "99 unforced errors between the pair of them in a four setter. That takes some skill."
From anon via text on 81111

BBC 5 live's Jonathan Overend on Twitter: "Well done to Novak. Very impressive match point - all the top guys have such big egos they love to close games out for the cameras...."

2351: She's right, I am tremendously excited and still coming to terms with tonight's sporting drama - Yanina Wickmayer in the US Open semis. And we have the night session to come in a few minutes' time with American Sensation Melanie Oudin, to give her full name, up against Denmark's Caroline Wozniacki in the first match, followed by Roger Federer taking on Robin Soderling for the third Grand Slam in a row. Lucky old Robin. Please manually refresh to de-Cheese the top of the page.

2342: NoDjo does a leap of delight as he wraps up a 7-6 1-6 7-5 6-2 victory. A not very convincing win for the world number four, but he doesn't look bothered about that, funnily enough. Very shortly, Melanie Oudin meets Caroline Wozniacki will be on court for the first match of the night session. Expect a packed Arthur Ashe Stadium - and a very excited Piers Newbery to take you through it. Bye bye.

2339: Verdasco paints the sideline with a forehand screamer to finish off the game and delay the inevitable. He'll get some more treatment at the changeover, but I fear there isn't a lot of point. Djoko will serve for the match at 5-2.

2131: Perhaps that last game was Nando's last stand... He is now down two breaks and trailing 4-1. Djoko two holds away from the semi-finals.

2328: THIS MATCH IS RIDICULOUS. Just when you think Djokovic is in complete control, leading by a set and a break, he loses focus and double-faults to give Nando a break-back point. He saves it though with a big serve and easy put-away. Scintillating point at deuce, the pair whacking balls at each other with increasing power before NoDjo wallops a backhand down the line. He leads 3-1.

2323: Looks like an existing abdominal injury for Verdasco. He's back on his feet now, but I'm not feeling all that optimistic about that his hopes of pulling this one out of the fire.

2321: You'll get no prizes for guessing that Nando just lost his serve. He hobbles a bit as he trudges back to the chair where the trainer will be waiting.

2318: The trainer lurks at the back of the court - for Verdasco I assume. We shall find out at the changeover. Level at 1-1 in the fourth.

BBC 5 live's Jonathan Overend on Twitter: "This Djoko/Verdasco match is like being stuck behind a horse and cart on a B road. Like the look of it but really want to get round it..."

2313: Nando is on the brink as he faces three break points - but the Spaniard saves all three to go 1-0 up in the fourth set. NoDjo is absolutely fuming, hammering his foot with his racquet repeatedly.

2307: Perhaps Nando will be cheered up by the sound of the Village People's YMCA blaring out from the Arthur Ashe sound system... oh no, wait, he's retreated to the locker room for a bathroom break. Can't say I blame him.

2304: Easy in the end. Nando saves one set point with a sweeping backhand winner - but Djoko bangs down a big serve and is rewarded when the return flies long. The world number four leads by two sets to one.

2300: Djoko holds easily... and then has two chances to break when Verdasco swings wildly at a volley and sees it fly over the baseline when he had most of the court to aim at. A big serve, followed by a booming forehand gets the Spaniard out of trouble - but only momentarily. Djoko earns a third - and takes it when Nando wellies a forehand wide. The fourth seed will serve for the third set at 6-5.

2250: Verdasco marches to the chair with a 5-4 lead in the third set. Very difficult to predict who will prevail in this fluctuating set - and indeed match. The winner, if you need reminding, will face Roger Federer or Robin Soderling in the semi-finals.

2242: Ai, ai, ai. What is this? Two double faults in the game from Nando and the Djoker has another break point... saved. Epic rally at deuce, Nando winning it when Djoko nets and the Spaniard moves ahead at 4-3.

2237: Well, well. Time to drag out the 'it's not a break unless you consolidate it' cliche. Some heavy hitting from Verdasco and Djoko mis-hits off the forehand side. Break back and it's 3-3.

2231: NoDjo has found some energy at last. A big return rocks Verdasco, who puts his forehand into the net, and the world number four has broken serve for the first time in the match to lead 3-2.

2228: Signs of life from Djoko, who produces a stunning forehand-pass-on-the-stretch to take the first point of that game. A rare clenched fist from the Serb, who goes on to level at 2-2. Meanwhile, Venus and Serena are through to the women's doubles semi-finals after a bit of a battle against Chinese 11th seeds Zi Yan and Jie Zheng, winning 7-5 6-4.

2223: Djokovic threatens to give his racquet the treatment as another forehand hits the net. Verdasco smashes into the net - and looks accusingly at the sky - to allow Djoko back to 40-30 but an ace makes it 2-1 to the Spaniard in the third set.

2219: More trouble for NoDjo, who is retreating further and further behind the baseline. So what does Nando do? He hammers a forehand into the corner and then feathers the half-volley just over the net, leaving the Serb with no chance. Break point... but Djoko gets some depth on his groundstrokes and forces the Spaniard to net. Potentially important hold for the former finalist.

2211: I frown on such shallowness, Kate (see below)... although only because there's no way Marat Safin can qualify. Djokovic looking a bit flat here, not unlike Murray yesterday. What is this malaise sweeping through the top seeds? Verdasco off and running in the third set at 1-0.

From Kate via text on 81111: "I would love it if Nando could go a bit further in this tournament, so he can qualify for the finals at the O2 and I can see him in the flesh!"

2203: Verdasco performs a slam-dunk smash to get back to deuce and then NoDjo makes a mess of a forehand to give the Spaniard a set point. He saves that with an ace but a sizzling forehand return sets up another. Backhand into the net. Nando takes the third when he scrambles back a forehand and Djoko nets. Second set done and dusted, 6-1. Interesting...

2200: Now it's NoDjo who's all shoulders shrugging. He trails 5-1 and surely this set is now gone?

2156: Hmmm... Verdasco rips a forehand pass cross-court - but it was a gift of an approach from Djoko, who seems to have lost his way completely. The Serb mis-hits a forehand miles over the baseline and Nando has three more break points - but Djoko saves them all. However, the Spaniard earns another and takes it with an astute approach to the net and a sweet volley. Now 4-1 up.

2143: Hello... Fernando Verdasco's booming forehand comes into play and he takes the first break of the match, jogging to the chair to celebrate his 2-1 lead in the second set. Those of you enquiring about the Bryan brothers' album (see 2111), I haven't heard it so I really can't comment. I think it's only available in the States at the moment, so maybe someone over there could give us a review?

2141: Nando doing a decent job of regrouping here, but he must be ruing those two set points in the first set. Djoko really didn't play all that well, but still won it. It's 1-1 in the second.

2136: That last text is incorrect. Roy "Emmo" Emerson never played Rocket Rod in a Wimbledon final. This is getting out of hand. Can we settle on Rafa and Roger being the only pair to play in all four Grand Slam finals in the modern era then? If they both get to Sunday's final, that is.

2133: Verdasco shrugs his shoulders as a big serve flies off the frame of his racquet. It gives Djokovic a 5-2 lead in the breaker - which becomes 6-2 when the Spaniard hits the tape with a big forehand. The world number four's forehand clicks into gear at the right time, and he takes the first set.

2126: And you thought British interest was over in the men's singles... Alison Lang is in the chair for this first quarter-final, and she tells Nando in no uncertain terms that NoDjo's serve was in. It's an ace and takes us to the tie-break.

From anon via text on 81111: "Re 2052: Laver met Emerson in the final of every Slam. Not Open era tho."

2121: A 14th unforced error - and another one off the forehand - from Djoko gives Verdasco two set points. Couple of beefy serves get him out of trouble though. It's 5-5.

2115: The forehand, usually Djoko's bread and butter, isn't behaving at all today. Verdasco holds to 15 to make it 5-4. Wilander-Lendl isn't one that usually comes up when you're talking great rivalries, is it? Although there was that 1988 US Open final...

From Kim, up late tonight for Federer, via text on 81111: "Re 2052: I think it would be. Lendl and Wilander faced off in three out of four. Otherwise you have to look at Evert-Navratilova or Graf-Seles, who played the finals of all four majors."

From Tim via text on 81111: "Re 2052: Closest I believe is Laver v Emerson who played in all but a Wimbledon final in the majors."

2111: The Bryans' defeat means they can concentrate on plugging their new album, which features the rapping of Andy Murray and Novak Djokovic. A sentence I never thought I'd write. And never wanted to either, if I'm honest. Still on serve between Djoko and Verdasco at 4-4.

The Bryan Brothers tweeting after their earlier defeat: "To quote three wise women: I'm a survivor, I'm not gonna give up, I'm not gon' stop, I'm gonna work harder, I'm a survivor!"

2101: Ooh, now, I think some of you may have misunderstood the text about Roger-Rafa Grand Slam finals. 'Anon' wasn't just talking about this year. Hopefully, a clever person will text soon... Not that you're not all clever... Oh, you know what I mean. I reckon Nando must win this first set if he's going to beat NoDjo and he's not doing too badly so far, leading 3-2 but still on serve.

From Pickles91 on 606: "I'm glad Murray had that performance, he lost in the previous three Slams playing well but had three players playing brilliantly. Yesterday was the first time Murray has been truly awful lacking everything. Might just be the push to get more aggressive."

2056: Er, 31% actually. I don't think anyone would argue that Murray played one of the worst matches of his career yesterday. In fact, I can't remember ever seeing him play so badly. Why? I don't know. Quick and easy hold for NoDjo and it's 2-2.

From anon via text on 81111: "Is it true Cilic was serving at under 30% in the second set? Anyone playing decent would have bagel-ed that set. Murray lost it 6-2. Still, that was yesterday, this is today. Go Verdasco! I'm in an underdog mood."

2052: What a great question that is (see below). I only wish I knew the answer. I'd guess yes - although I realise you weren't asking me to guess. Anyway, Verdasco's serve gets him out of a big spot of bother, saving two break points to go 2-1 ahead.

From anon via text on 81111: "Caroline, I have a question for your lovely self... if Federer and Nadal reach the final will it be the only time in tennis history that the same two men have faced off in the final of each of the four Grand Slams?"

2047: Both Nando and NoDjo have gone for the mustard shirts this evening. Nando is swinging away early on here, while NoDjo's radar is a bit off, but after several deuces, we're level at 1-1.

2041: I've got builders working at my flat at the moment. Yesterday, as I left for work, I boldly predicted that Andy Murray would win the US Open. Inevitably, and rightly, they laughed in my face this morning. The media - both British and international - haven't been kind to old Muzza today. My own favourite tennis scribe, Sports Illustrated's Jon Wertheim, says: "Despite the strides he made this year, Murray has underperformed in Slams, none more than this one. I'm already getting questions about why Murray doesn't face the same scrutiny for coming up short in majors that Dinara Safina does. Well, Murray hasn't been ranked number one, the source of Safina's troubles; and his winning record against Roger Federer helps his credibility. But the knives will come out after this one. A favourite going into the Australian Open, Murray fell to Fernando Verdasco, a loss that looks worse in retrospect. A favourite going into Wimbledon, Murray fell to a red-hot Andy Roddick in the semi-finals. Disappointing. A favourite and second seed coming into the US Open, he loses, somewhat shockingly, with a lacking effort against a guy outside the top 10. That's not going to cut it."

2038: They're under way on a very windy Ashe, and Fernando Verdasco holds serve comfortably against fourth seed Novak Djokovic.

2036: Now then, I realise I'm up against the football tonight, but that means you've got a better chance than ever of being published, so get the texts trickling in on 81111, get chatting 606 or tweeting on Twitter.

Yanina Wickmayer after reaching the semi-finals: "It's amazing. I still can't believe it. It's just great. It's the first time in my life I've played a tournament for longer than a week. You just have to rest and keep focusing."

2029: Of course, the real reason for the delay in the start of this live text was so Heather Watson didn't fall victim to the Curse of Cheese. Britain's junior number one, seeded 13th in New York, saw off American Courtney Dolehide 6-3 6-2 to reach round three.

2024: Yanina Wickmayer is already celebrating victory over Kateryna Bondarenko, the unseeded 19-year-old winning 7-5 6-4 in a fairly ropey encounter to reach her first Grand Slam semi-final. She'll face Melanie Oudin or Cazza Wozniacki, who play in the first match of the night session and are followed by Federer v Soderling. Up now: Novak Djokovic v Fernando Verdasco.

2020: Ah, hello there. Sorry for the delay. My fingers simply refused to type after the demise of Andy Murray yesterday. Onwards...
