0604: That's your lot for day two, day three gets under way in just 10 hours' time. Which seems a bit weird. Live texting resumes at 1600 BST, with game-by-game and 5 live sports extra coverage of Andy Murray v Lukas Lacko at 1800 BST. And if that's not enough, Elena Baltacha should be in action against 27th seed Petra Kvitova at around 2200 BST this evening. Goodnight. Or morning.

0554: Top seed Caroline Wozniacki beats Chelsey Gullickson 6-1 6-1 in 60 minutes, and the few hundred souls remaining on Arthur Ashe Stadium do their best to whip up a bit of whooping and hollering as the Dane applauds them.

0544: The errors are flowing now from Gullickson as she continues to go for everything. An admirable stance but it leaves her a set and 4-1 down. Wozniacki still looks absolutely livid every time she loses a point.

0541: After his earlier workout, Rafael Nadal says: "I served well. Concentration was good. The forehand is working well. The backhand is improving a lot and it just remains to have a bit more confidence, but that's the only thing. The basic things are really in the right way. I hit some terrible shots on the break points, but I played well in the tie-breaks and that's important for the confidence."

0533: Gullickson gives Wozniacki's second serve the treatment in a tight game but the Dane holds on for 2-0. Is it just me who thinks of Hamlet every time you hear 'the Dane'?

0523: Wozniacki takes the first set 6-1 in 29 minutes but Gullickson isn't doing badly. Natasha Zvereva lost a French Open final 6-0 6-0 to Steffi Graf in 1988 and that only took 32 minutes. Now that was embarrassing.

pottiella on Twitter: "I've heard about 3 different commentators/pundits in the past week say Wozzy plays like Muzz - would you agree?"
Up to a point in that they're both natural counter-punchers, but Murray has shown he can be more aggressive and take the initiative against the top players whereas Wozniacki hasn't yet. She's improving all the time though, wouldn't rule it out.

0510: Gullickson is putting up a decent fight and doesn't look overawed, saving a break point to get on the board at 3-1 down, but the pace that Wozniacki sets is generally too much for her. Some say the Dane doesn't have a special shot that can land her the major prizes, and she's yet to beat one of the really big names, but her athleticism is not in doubt.

From Matt, Blackburn, via text: "I'm still here Piers. Wouldn't go to bed before the lovely Caroline's won. Could open up for her this year methinks."

0459: Moments later, Wozniacki breaks to love for 2-0. This could be a quick one.

0456: Blimey, fair play to Gullickson she comes out firing from the baseline - you can tell she's coached by Harold Solomon, the man who has worked with the likes of Jennifer Capriati and Monica Seles, as she can certainly hit her groundstrokes. Playing in her first ever match at tour level, let alone Grand Slam level, she earns a break point before Wozniacki recovers to hold serve.

0447: To say this is a daunting task for Chelsey would be understating it. The American, who turned 20 on Sunday, does not have a world ranking. Wozniacki has and it's number two. "I know who I'm playing and I think I've played her in the juniors but I haven't really thought about tactics or anything yet," said the Dane the other day.

0443: A quick burst of the US national anthem goes down well with the rather sparse looking crowd in Arthur Ashe Stadium. It is getting on for midnight in New York, but then it's getting on for 5am here and we're still up for it, no? World number two and top seed Caroline Wozniacki is about to play American wildcard Chelsey Gullickson.

0432: You wait nearly three hours for a break of serve and then two come along at once. Rafael Nadal nails a forehand down the line to earn three match points and takes the second for a 7-6 7-6 6-3 win over Teymuraz Gabashvili.

British doubles player Ken Skupski on Twitter: "2nd after 11am on court 12. Can't wait to finally get started. US Open has been roasting so far and we expect the same tomorrow! Boom!"

0421: Yikes. Nadal gets two more break points and charges into the first like a man possessed, creating a huge gap to thump away a backhand... and he sticks it in the tramlines. Big gasps all around the stadium. Gabashvili then uses his forehand to batter away at Nadal and save the second break point of the game, and seventh of the match, but then dumps a backhand into the net. Break point number three... and this time Gab hammers a forehand into the net. I can't deny it, I'm relieved. Nadal leads 7-6 7-6 4-3.

0409: The end is surely nigh for Gabashvili... but no. He serves his way out of trouble again and we still await the first break of serve as Nadal sees a fifth opportunity of the match go begging. Gab, who has swapped the grey t-shirt for a crisp white, leads 3-2 in the third set.

0400: And Andrea Petkovic takes the win, beating 17th seed Nadia Petrova 6-2 4-6 7-6 (7-4) on Louis Armstrong Stadium. That just leaves Nadal and Gabashvili, on serve early in the third, before Wozniacki rounds things off against Gullickson.

0353: Over to Armstrong and it's a final set tie-break for Petrova and Petkovic....

0346: There are danger signs for Nadal when a pumped-up Gabashvili breaks early in the tie-break but the Spaniard remains calm and works his way back into it. Gab hammers a tempting forehand wide to fall 4-2 down and that is that. Nadal leads 7-6 7-6, Gabashvili gives his racket the treatment.

Svetlana Kuznetsova on Twitter: "Gonna go sleeep, watchin Rafa play with Timur my russian friend! we played with him tournaments when we we 12))))long time ago! good night to all of you! sweeeeeet dreams!"

0337: Fabulous stuff from Nadal, who steps in and cracks away a backhand before moving into the net to chop off a volley for two set points.... equally good stuff from Gabashvili as he saves them with a huge forehand and a sharp volley of his own. Time for tie-break two...

0329: We look to be heading for another tie-break on Ashe as serve continues to dominate, with Nadal leading by a set and 6-5, while Petkovic and Petrova are locked at 3-3 in the decider on Armstrong.

0321: James Blake, a first-round winner today, denies his role in the opening ceremony suggested imminent retirement. "A couple of people mentioned something like that to me," says Blake. "They're trying to get rid of me. I hope that's not the case. It's still exciting for me to win a match here and to have fans that are excited to see me play."

0313: Gabashvili is not going away in this match and it remains on serve in the second set, Nadal leading 4-3 after one hour and 40 minutes.

0308: "I wasn't worried about what happened at Wimbledon - it wasn't on my mind," says Fernando Verdasco after beating Fabio Fognini to avenge defeat by the Italian at the All England Club. "All I was thinking about was how I was going to beat him."

0258: Gabashvili fends off an early break point in the second set and it's hard going for Nadal, despite the 7-6 2-1 lead. And Petrova levels up at one set all against Petkovic on Armstrong.

From Genghis26, Cambridge, via text: "What is it with the laughing at names on here? Piers is hardly the most normal name, what what?"
Who's laughing? I like any names that have been highlighted. Nothing wrong with having an unusual name anyway, as I was telling my butler only the other day.

0252: The full order of play is now out for tomorrow/today/whatever, and as well as Andy Murray finally playing some tennis at 1600 BST we have the prospect of his fellow British number one Elena Baltacha against Petra Kvitova. They're fourth on Court Six, I'm guessing at about 2200 BST. Murray will be live on 5 live sports extra, details will follow regarding Baltacha's matcha.

0247: Vera Zvonareva describes her earlier 6-2 6-1 win over Zuzana Kucova as "easier than it looked from the outside". To be honest, Vera, it didn't look to difficult from here.

0239: They'll be dancing in the streets of Cordoba - David Nalbandian comes back from a break down in the final set to beat Rik de Voest 7-6 3-6 6-4 6-7 6-4. Good to have the big man still in the tournament. I don't think he can win it but I reckon he could stop someone else significant from doing so. Meanwhile, Nadal takes the tie-break 7-4.

0232: Tie-break time on Ashe and Gabashvili opens with a horrible snatched volley into the net before Nadal wallops a forehand into the corner and soon finds himself 3-0 in front...

0225: Petkovic is a set and a break up on Petrova and Gabashvili leads Nadal 6-5 on serve. Nalbo breaks back and it's 4-4 in the fifth against De Voest on Court 11. And Coco Vandeweghe has a brother called Beau.

0216: It's still very much even stevens on Ashe as Gabashvili holds to make it 5-4. Both men have had a break point but neither has any sort of edge yet. I have to say that I'm backing Rafa over Roger in their choice of night session attire, even though Rog takes advice from American Vogue editor Anna Wintour. "I kind of ask her sometimes what she thinks," he told New York Magazine. "I get a very strong second opinion. I asked her about the pink colour I was wearing last week and she was like, 'Oh, you sure about that, Roger?' Too late now."

0204: We're down to three singles matches remaining on day two after talented German Sabine Lisicki defeats brilliantly named American Coco Vandeweghe 6-1 6-0. I picture Coco as an impossibly elegant 1930s heiress living in a Gatsbyesque mansion. It doesn't mention any of that on her WTA profile though.

0159: World number 46 Denis Istomin beats Maximo Gonzalez 7-5 7-5 6-1 to set up a second-round meeting with Nadal or Gabashvili - 3-3 in that one. And Nalbo's a set down!

From Paul, Sutton, via text: "Hey Piers, just to let you know that i did manage to stay up last night and watch Roger win, but even more impressively i DID manage to pass my driving t est after 4 hours sleep! Federer's performance gave me the drive to pass!"
Congratulations! You're almost certainly more proficient already than my taxi driver at 5.30am this morning. Terrifying.

0151: David Nalbandian fails to convert a match point and Rik de Voest capitalises to win the fourth set tie-break and force a fifth on Court Eight, probably condemning someone courtside to an earful of industrial Spanish. Nadal and Gabashvili are 2-2, as are Petkovic and Petrova.

0138: Gabashvili holds serve in the opening game and I fancy him to give Nadal a few problems. Only a few, mind. De Voest is on serve at 6-5 against Nalbandian, but if I know Dave he'll be relishing this challenge. Absolutely relishing it.

0130: OK, Rafa is out on Arthur Ashe Stadium dressed head-to-toe in black, as has become the custom for the big names in New York night sessions. Gabashvili is sporting a grey top and white shorts. A lower profile but potentially interesting match has just got under way on Armstrong between German funnywoman Andrea Petkovic and experienced Russian Nadia Petrova. Kettle.... on!

0120: "I knew I had a tough first-round opponent," says Maria Sharapova. "She came out firing and didn't give me many opportunities. These are the types of matches you want to get through to try and get better."

0117: Ah, technical issues. I'm considering ringing my mum tomorrow and seeing if my ZX Spectrum is still in the attic. Nalbandian, who has been so brilliant in recent weeks, looks like he could really do without 30-year-old Rik de Voest playing the match of his life today. The South African leads 4-3 on serve in the fourth set.

0107: Right then, according to my calculations we are on course to see Nadal next on Ashe, although there will be a delay while the day crowd leaves and the nightshifters move in. There may well be a day two opening ceremony involving Celine Dion too, although fingers crossed. And seventh seed Vera Zvonareva has just beaten Zuzana Kucova 6-2 6-1.

From Rajeev via text: "Arthur Ashe actually went slightly longer than Safin in the open era between 1970 and 75 (by a couple months)."

0055: Brilliant stuff from Maria Sharapova as she races through the final set to beat Jarmila Groth 4-6 6-3 6-1 - a true champion's performance against an opponent who began in almost unplayable form. And Fernando Verdasco has finally seen off Fabio Fognini 1-6 7-5 6-1 4-6 6-3.

0048: Oh dear. Groth makes it 13 double faults and does so on break point, muttering to herself, "I can't do this." If she's referring to serving, I'm afraid she's correct. Sharapova then plays her best service game for a while to make it 4-1 and she's closing in.

0041: Fernando Verdasco - or tabasco as Brad Gilbert calls him - gets the vital break in the fifth set against Fognini and leads 4-3, Nalbandian is serving for a two sets to one lead over De Voest, and Sharapova edges 2-1 up on Groth in a tense, gritty and loud encounter.

From Stuart in Birmingham via text: "Think the longest gap between grand slam wins was Ken Rosewall won US in 1956 next win was Aus in 1968."

0035: A long, long game sees Groth's 11th and 12th double faults of the day put her in trouble before she fights her way out of it to level at 1-1 in the decider. And Wimbledon finalist Vera Zvonareva is out on Louis Armstrong Stadium and leads Zuzana Kucova 5-2.

0021: Sharapova has two set points on the Groth serve but makes two forehand errors, only to fire a backhand winner for set point number three... and Groth double faults. One set all. Verdasco and Fognini are into a fifth and Nalbo has an early break in the third. "Let's Dance," croons David Bowie over the PA system. Not now, Dave, bit busy...

From Lou via text: "Any chance of a separate Murray live text tomorrow so we can have a play by play account of the match, please?"
Absolutely, it will be game-by-game for Murray and there will be live commentary on 5 live sports extra

From Jon via text: "I think the longest wait of the open era is Safin. Us 00, aus 05. A rods still longer."

0010: I've just realised... it's September. Flip flops back in the cupboard today then. Nalbandian has dropped the second set against De Voest, which is a pretty big surprise in itself, while Sharapova remains a break up in the second at 4-3. Could be a while until Rafa.

2359: Sharapova clenches her fist after recovering from 0-30 to hold for 3-1. Don't forget, we've got Nadal against Gabashvili to follow this one, with Wozniacki and Gullickson after that. Meanwhile, Matt Majendie of Reuters has just informed me: "The people in the press room have just brought round free beer and nachos to lighten the mood. It's certainly worked for me." They don't know they're born over there....

ABAtweets on Twitter: "What's the longest a GS winner has gone between winning slams? Wondering if Roddick won #usopen whether 7yrs would be a record."
Obviously I know the answer but I'd rather let one of you, the public, grab a moment in the spotlight. So come on, hands up....

2349: Good news for wildcard James Blake as he beats Kristof Vliegen 6-3 6-2 6-4 on Armstrong, while Sharapova fends off a break point top move 2-0 up on Groth in the second set. Hard going for the former champ though.

From anon via text: "Some big hitting by Groth but I still say sharapova in three. Come on Maria!"
It might be working - Sharapova breaks at the start of the second set

2338: "Have some of that!" is what Groth surely mutters under her breath as she absolutely hammers a forehand return on set point to make up for her previous game - she takes it 6-4 and Sharapova has it all to do. Meanwhile, Nalbandian has nabbed the first set tie-break against De Voest and Verdasco is two sets to one up against Fognini.

Alexlawson8 on Twitter: "Sharapova has won her 3 majors in 2004, 2006 and 2008. Surely she will keep the pattern going and win another in 2010?"

2332: Groth serves for the first set and, not coincidentally, sees her form dip alarmingly, dumping a backhand into the net to hand Sharapova the break back. The Russian trails 5-4 on serve. And while I catch up with what's going on, you can get in touch via Twitter or text on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message.

2328: A couple of results - David Ferrer beats Alexandr Dolgopolov 6-2 6-2 6-3 on Court Seven, and Julien Benneteau beats Radek Stepanek 6-4 6-2 4-6 6-4. Meanwhile, Novak Djokovic is asked how he felt when the sun dipped behind the stands during his five-set epic. "Oh my god. It was like, I don't know, sleeping with my girlfriend I guess kind of feeling."

2322: A quick scoot around Flushing Meadows sees James Blake closing in on a much-needed win against Kristof Vliegen on Armstrong, Fernando Verdasco edging towards the third set against Fabio Fognini on Grandstand, and David Nalbandian heading for a first set tie-break against Rik de Voest on Court 11.

2315: Evening all, please manually refresh to erase all memory of Ashenden and we can move on. Plenty of pre-match chat suggested Groth would give Sharapova trouble tonight and so far that's proving the case. The newly-confirmed Aussie is going for everything and it's coming off for now - Groth leads 4-1.

2306: It's time to wrap up my live text and warm up the baton for Piers Newbery. In the mean time, may I thank you for all your comments, your jigging, and I'll gently fade away as I gaze with admiration at Sharapova's stunning turquoise - possibly light electric blue - outfit. More of the same tomorrow with the Muzzman. Night. Here's the boy Newbery to take you into Wednesday. Be gentle with him.

2300: Can Sharapova win again at the US Open after her triumph in 2006? Just two third round spots since then. A few people tipping her for more glory. How can she be only 23 though? She's been around for ever. Tonight, she's up against Australian Jarmila Groth (originally from Slovakia). Groth is currently ranked 56, aged 23, and has only once got past the US Open first round - reaching the third four years ago.

Andy Murray on Twitter: "Pretty toasty here today. Takes the edge off the ice bath.."
Muzz on at 1800 BST Wednesday. Anybody taken an ice bath before? Crikey is all I can say. Makes me think of all those times I've taken 20 minutes strolling pathetically slowly into the sea as the icy temperatures slowly rise up the legs. A quick dive in is always the best way, isn't it?

2240: Somebody had better wake up Maria Sharapova. She's on after this on Arthur Ashe. Wait a minute. I should have known. Troicki goes 30-0 (he's only one service break down) but he blows two shots and it's 30-30. Three hours and 40 minutes and Djoko does it! Phenomenal. Magical match. They're best mates as well. Djoko wins 6-3 3-6 2-6 7-5 6-3. What do you make of that then? Time for you Sharapova. What have you got in your tank I ask. And Charlotte - you can stop jigging now. Great effort.

2237: The Troicki battle is almost over. Djoko is now 5-2 up in the final set. Troicki serving to stay in the US Open. What a match. Match time 212 minutes. Big service hold for Troicki. Here we go then - Djoko's serving for the match.

thetonyjones on Twitter: "How about a little love for the colonies? 205th Canadian Peter Polansky wins first GS match ever over 30th seed Juan Monaco"
With a Canadian wife how I could refuse such a request. Tony - I hereby throw over a huge amount of love for PP's fine efforts. I've just done some research on Mr Polansky - seems like at the age of 18 he was in Mexico for a Davis Cup match, woke up sleepwalking and jumped or fell from a three-story room suffering serious injuries. Nice to see him in great shape today.

Greg in Romsey, via text 81111: "I would personally prefer Rafael Federer, wicked name. Then also for the sake of this text commentary can u be known as Piers Ashenden, that would also save us the trouble of refreshing the page"
Mmm a tricky one. I think my mum may take a quick glance at the live text commentary later and have a heart failure thinking she's got a forgotten son. I might be wise not to agree with you on this one.

2224: Chinese eighth seed Li Na, after losing to Ukraine's Kateryna Bondarenko, said a short time ago: "It was so hot. I felt good in the first set. The second set, I felt like I died. The energy just faded."

2221: Has the tide turned on Arthur Ashe? Djoko bags his third game in a row and he's leading 3-1 in the final set. It's Troicki's turn to look beaten and weathered.

2218: American James Blake, who recently mentioned possible retirement because of a knee injury, is 3-2 up against Kristof Vliegen. Italian Fognini is doing famously against eighth seed Verdasco, after taking the first set 6-1. He trails 1-3 in the second. Kirilenko (23rd seed) is 6-5 up against Zahlavova Strycova. In the men's, Ferrer leads 3-2 against the magnificently named Dolgopolov. Stepanek (28th seed) was two sets down to Benneteau but he's pulled one back. 30th seed Monaco is OUT - he loses to Canadian Polansky 2-6 6-7 3-6.

Charlotte in Denmark, via text 81111: "It's charlotte, not caroline but yes i'll be jigging till he's won. My services are available for all players at reasonable notice"
Oh blimey. It's all getting to me. Sorry. It's Roger Nadal and Charlotte Wozniacki up later right?

2206: Just when you thought Djoko had ironed out his wobbliness, he loses his serve at the start of the fifth set. But now there's hope. It's deuce and Djoko leaves a Troicki volley which lands on the line. Djoko looks up and seeks divine intervention. You'll have to do better than that to get any help from the big man Novak. Oh lordy - somebody shouts during the rally and Djoko lays an easy one into the net. He aint a happy boy right now. It's deuce again after a line call goes in Djoko's favour - by the smallest of margin. And he does it and breaks back. Drama-tastic. 1-1. Immense.

2201: Don't forget the tennis show on BBC Radio 5 live right NOW. Baltacha just leaving the studio but John McEnroe will be giving his opinions in a couple of minutes. Is there a man in sport more listenable that the mighty Mack? I say NO. Get your wireless on anyway.

Jamie in Portsmouth, via text 81111: "Djokovic out of sorts and hanging on in there in the city that never sleeps. Let's hope Andy Murray is on song tomorrow"
The city that never sleeps eh. Portsmouth surely is the same no?

sssssarah on Twitter: "Yehheeeeessss, Djokovic takes it to a fifth! Come on!"
Would I be right in thinking you want Djoko to win?

2153: Djokovic gets it back to two sets all. He's earning his corn today. 172 minutes so far. Troicki winning the battle of the stats with 52 winners and 19 aces. Look at the scorebook though eh. Which way is this going to go? Hey Danish Caroline - are you still jigging over there?

2152: My colleague Piers Newbery will be taking over a bit later and he'll be overseeing Nadal and Wozniacki on Arthur Ashe with live text duties. They'll be on soon after the hour of midnight.

2148: Troicki and Djoko are 5-5 in the fourth. This is one bum-squeaker of a game and it's 30-30. Djoko digging out some hidden energy and he whips in a flurry of booming forehands to force Troicki to play it long. Game over. Djoko leads 6-5. This Serb battle is boiling up to be a right corker.

2146: The Argentine Eduardo Schwank comes through with a sweet victory over Robby Ginepri 6-4 7-6 (7-3) 4-6 6-3.

2142: A big old shock in the women's singles. Ukraine's Kateryna Bondarenko causes a major upset by dumping out eighth seed Li Na, the highest Chinese seed in Grand Slam history, 2-6 6-4 6-2.

Martyn in London, via text 81111: "Really feel for Anne but worried by her comments. Only hope they are spur of the moment.... She's not far off where she needs to be to be back in the top 100. Look at her in the 1st set today. She just needs a bit more consistency and some self belief. The confidence seems a little fragile. Keep on keeping on, Anne. We all admire you for your comeback after so long out injured and know you have the top 50 player still in you."

JoshPowling on Twitter: "Djokovic may scrape through this match, but a punishing five-setter is not what you want in the first round."

2134: Bit more on Djoko now that he's pulled his finger out within seconds of me larging it about Troicki. Typical. Djoko's record in the US Open is decent - runner-up in 2007 and two semi-finals in the last two years. His current form in Grand Slams this season? Quarters at the Aussie Open and Roland Garros. Semis at Wimbledon. US Open in 2010? Time will tell. He's still got some work to do to stay in this year but he's turning it around. Slowly.

2131: Hold on. That Danish jig (do they jig in Denmark?) by Charlotte has clearly done Djoko a favour. He's only gone and broken back from nowhere. Fair play to the sweaty Serb. He breaks back and Djoko now leads 4-3 in the fourth set. Stunning.

BBC 5 live's Jonathan Overend tweeting from Flushing Meadows: "An hour of tennis on BBC Radio 5 Live 9.30-10.30pm BST. John McEnroe, Elena Baltacha, Jeff Tarango & much more. Hopefully Annie K too."
That is officially in two minutes. Get tuned in.

Charlotte in Denmark, via text 81111: "Novak will pull through. He usually has the last laugh. They don't call him the Djoker for nothing"
You had better start doing your Djoko dance. He holds serve and trails 2-3 in the fourth set. He's still a breakdown though.

2122: A weary Djokovic is left gasping for breath after a gruelling baseline rally and he desperately looks for solace with a line call but Troicki's long shot was bang on the line. Bit desperate that. Djoko trails 1-3 in the fourth set. The shock is officially on. So who is this Troicki? He's played in two US Opens with his best showing in NY in 2008 with a third round spot. He's aged 24. Current world ranking is 45. His best effort in a Grand Slam this year was at Roland Garros, reaching the third round. He's never got beyond the third round in a Grand Slam. I wonder who Serbian tennis fans will be singing and crying over tonight?

2111: A few words from a tearful Anne Keothavong following her three-set defeat by Chan: "My ranking and my tennis isn't where I would want it to be, I have higher expectations for myself. I'm not the player I was two years ago here (when she reached the third round). Who knows what's going to happen after this? I'm going to need time to reassess and decide what I want to do."

2108: Djoko, a former US Open finalist, could be heading for a tumble at the first hurdle. Troicki is 2-0 up the fourth set and 2-1 in sets. Djoko looks booshed. That means very tired, hot and sweaty by the way.

2101: I repeat, Andy Murray is on tomorrow for his first-round clash with Lukas Lacko but not before 1800 BST. You got that? That sounds like a rush back home after the office or just stick around and follow the action out and about on your laptop or phone. The Scot has got to have ants in his pants having to sit and chill and play keepy-up for 2.5 days.

2058: Not looking good for Djokovic who returns to his chair and smashes his weapon against his monster bag. He loses the third set to Troicki 2-6. The Serb is struggling (against the other Serb).

2056: Oh lordy. Djoko is a break down and trails 2-4 to Troicki in the third set. His shoulders have slumped. The boy needs a new clothing range. China's Li doing OK and leads Bondarenko 6-2 4-3. Fish is flying - he's 4-0 up and serving at 4-0 in the decider. Looks like Hajek has run out of gas. Schwank is serving for the match against Ginepri. Robredo is 6-4 6-3 and 4-0 against Rosol. Stroll in the park for the Spaniard so far. 26th seed Safarova leads Paszek 6-2 4-1. Other men's seeds struggling are Monaco (lost first set to Polansky) and Stepanek - also trailing by a set to Benneteau.

2046: Having said that about Andy Murray, my colleague Piers Newbery (who will be arriving for the later games) has heard on the US grapevine when the Muzz is playing.
Piers Newbery on Twitter: "Sky's @PetchTennis says @andy_murray will be on at 1800 BST on Wednesday, so 1pm local. Hot for AM, inconvenient for me. Why wasn't I asked?"

Will in London, via text 81111: "Murray - Aston Martin DB9: quintessentially british, stylish and has enough under the hood to see off 99% of the competition but just can't seem to get past the Ferraris where it matters"
Murray takes on Lukas Lacko on Wednesday. Time not known yet.

2039: Mammoth Monday has stretched into Tuesday. It's another whopping five-setter. Fish munches on another bagel (graphic time) and wins the fourth set. Strange one this one. American Mardy Fish wins sets one and four 6-0. Loses two and three to Jan Hajek. Where's this one going? Total points won so far - Fish up 116-84 and it's two sets all. There's a lesson there somewhere.

2034: With temperatures booming up through the thermometer at 109 degrees, Djokovic loses the second set 3-6. He opens up the third set with a steady service game though. This place needs my helicopter to fan the players down. Sweaty times.

A (desperately seeking sun in London), via text 81111: "Nadal...a Porsche cayenne...a white one. Big, in your face...but oh so gentle to drive"

Tom in Edinburgh, via text 81111: "Epic car comment from Martyn (see above 2011 entry). Not a player but a Brit tennis would be a Lotus: Lots Of Trouble, Usually Serious"

2028: On the back of Mirjana Lucic's earlier win over Australian Alicia Molik, we have a little gem from the WTA. "It's the same player who reached the 1999 Wimbledon semis (aged 17) and now at the age of 28 is back after disappearing from the game for the best part of four years (2003-07) - she faces Jelena Jankovic next". The 150th-ranked player hasn't played in the US Open since a first-round loss in 2002.

John in London, via text 81111: "Caroline is a deserved top seed. Won 3 tournaments in the last month and nobody else has shown any consistency. On their day only the Williams sisters and Clijsters can match her but she battles harder than anyone else and is developing more winner shots. She could win this year and will be a star for the future. Very charming as well."
Well put John. Sounds like you know the girl. Have you ever met her?

2023: Djoko is all red faced and looking a little ruffled. He's facing Troicki's serve and is 3-5 down in the second set. Oh my.

Sportenkortdk on Twitter: "Caroline's certainly been in great form as of late, but guess Kim C. is the more legitimate favourite. And I'm a Dane!"
Welcome on board the live text train. Nice to get punters from the land of bacon, Hamlet, Jesper Olsen and Wozniacki. To name just a few.

Martyn (still at work) in London, via text 81111: "If Wozniacki was a car, she'd be something like a Skoda Roomster..... Probably quite good, but not many have heard of it..... and it isn't going to draw the crowd. She needs to work on her branding....."
Now there's a statement. If I don't get at least 10 other comments on what cars certain players would be then I'll eat my computer keyboard with my rice dish later. Federer a Rolls Royce? What would Nadal be? What would Keothavong be? I'll leave the rest to you. And make them good - I don't really fancy digging out the tomato kethcup to help wash down my QWERTY.

2011: And we thought only Brits did the second set wobbles. Djokovic, hang your head and terrible hat in shame. After cruising to the first set, the third seed trails 4-1 in the second to Troicki. Perhaps he's feeling sorry for his Serbian compatriot.

2009: Would love to hear all your thoughts on almost anything (apart from any new Brians - I think my colleague Piers Newbery will self-combust if he has to read any other Brian comments tonight. Give me your predictions, thoughts on Andy Murray's match tomorrow, Keothavong, Baltacha's good showing, final set tie-breaks. Anything. Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or 606.

2005: Back to Keothavong. The former world number 48 - now ranked 142nd after a long injury lay-off - was treated for a problem with her feet in the third game of the deciding set. It's another blow-out after a good lead on the back of her defeat by Anastasia Rodionova in the first round at Wimbledon having led 4-0 in the final set. Fitness problems? Belief? What do you reckon?

2001: So what do you guys make of Wozniacki? A worthy top seed? The Dane is looking to go one better after losing to Kim Clijsters in last year's US Open final. Wozzo goes up against US wild card Chelsey Gullickson.

1957: It's Russian 14th seed Maria Sharapova coming up after this Djokovic match and plays Australian Jarmila Groth. Nadal and Wozniacki are slugging it out in the big evening games.

MarcusBackInKensington on 606: "Djokovic will never win anything wearing awful shirts and hats like that."
Mmmm fair comment. The shirt's OK but it looks like a four-year-old has dug their crayons out and been given half an hour to create some artistry magic on his hat. It's a stinker. My dad wouldn't even wear that and he's worn some shockers. A blue velvet cap on holiday in Wales a few years back I ask you!

1951: How's the Djoko doing I hear you cry. He's taken the first set 6-3 and doing OK without too many fireworks. In the women's singles, Radwanska looks in good nick and leads Parra Santonja 6-4 4-1. And it's time to wave goodbye to another Brit. Hutchins is out of the doubles.

1947: We're having a final set tie-breaker after a mammoth battle between German Rainer Schuettler and France's Benoit Paire. 209 minutes so far and it's gone down to the wire. Looks like Paire may nick this one. 5-2 up in the tie-break. And he does it.

1941: With Keo's earlier demise, it's left to Baltacha and Ross Hutchins in the doubles to fly the Union Jack at Flushing Meadows. The Hutch (playing with American Lipsky) is 4-3 down in the second set after losing the opener.

1938: A quick glance at Louis Armstrong and it's dramarama. Baghdatis saves one match point at 5-6 in the decider against Clement. And BOOM - the Cypriot is another seed to be dumped out. He loses 3-6 6-2 6-1 4-6 5-7 in a match that lasted 206 minutes. He won't watch to read the stats with total points won in the match - 137-128 in his favour. Now you do the math(s)...

HibaMS on Twitter: "I think Anne Keothavong is only good enough to play 1 set matches, if there were such..She always loses after winning 1st set"

1928: Time for a round-up me thinks. Baggo and Clement are 5-5 in the decider. Djokovic is 3-2 up in the first set. Mardy Fish (American 19th seed) took the first set 6-0 against Hajek but trails 3-5 in the second. The Argentine Schwank-meister is 4-4 with Ginepri after nabbing the first set. And Britain's Ross Hutchins in the doubles lost the first set on a tie-break and is 1-2 down in the next.

1922: Keothavong 6-2 1-6 1-6 Chan.

1919: Keo saves one match point. But it's too late. Keothavong LOSES.

1916: Mmmmm Keo is serving to stay in the match at 1-5. Shame. Any way back? The Brit needs a bloomin miracle. Something I didn't know was that Keo took a medical time-out in the third game of this deciding set. It is crispy hot out there. Hope she's OK.

1912: You know those Keo wobbles were were talking about. It's gone a whole lot more wibbly, wubbly wobbly. Chan is serving at 4-1 up.

1910: Many of you have been shocked at the demise of the so-called Ernie (by some 606 users). Yep, Latvian 24th seed Ernests Gulbis is no more at Flushing Meadows, losing 6-2 7-6 (7-1) 6-4 to France's Jeremy Chardy. Another fallen seed. Other results today in the men's draw: Spain's Daniel Gimeno beats Jarkko Nieminen 7-6 (7-1) 6-4 6-3. Pablo Cuevas beats Julio Silva 7-6 (7-0) 6-1 6-2. Feliciano Lopez (23rd seed) beats Santiago Giraldo 6-4 6-4 6-4. I thank you.

1904: It's the battle of the Serbs on Arthur Ashe. Viktor Troicki takes on the might of Novak Djokovic. Djoko takes the opening serve. Keo had a bag of points there to break back but she loses and now trails 3-1 in the decider. Time to raise your game Special K.

1858: Did I tell you Marcos Baghdatis and Arnaud Clement had gone to a fifth set? No? What am I doing? Apologies. Baggo's got a break in that one at 2-1.

1852: A mini wobble from Keo. We need to stand in a circle again, hold hands and do the Keo dance. Unless of course you want Chan to win. Which is fair enough. We're all one big happy tennis family here. Keo is 2-1 down in the decider with Chan now serving. Pressure on.

1848: A little heads-up on BBC Radio 5 live a bit later. 2130 BST - 2200 for a John McEnroe interview, plus interviews with Elena Baltacha and her coach Nino. Plus there's the magnificent Jeff Tarango.

1845: A stunning effort from Jankovic in those last three games. Halep was serving for the match but the fourth-seeded Serb hit right back under some serious pressure. Jankovic 6-4 4-6 7-5 Halep. Some nice stats from the WTA - Jankovic has (still) never lost in the first round at US Open. Her last first round loss in a Slam was five years ago at Roland Garros. Meanwhile, that was Halep's first US Open visit and just her second Slam competition (2010 Roland Garros).

1841: Keo and Chan are 1-1 in the third set. There you go. Short and sweet.

1839: Just as the excitement reaches fever pitch, I'm needing some refreshment. Not too much to ask is it? I grab an 'easy peel' satsuma and you know what's coming.....juice all over the keyboard. Sticky fingers. I've had a shocker I have to tell you. Anyway - Jankovic dishes up a few tasty serves and leads 6-5 in the decider. I'm thinking Halep needs to take a big gulp of chill juice before she plays this game. Her 2010 US Open campaign depends on it. Jankovic - for all her 48 unforced errors - has been brilliant just when she needed it. Help. I need a cloth!

1835: Jankovic plays a blinding forehand winner to make it 40-30 against Halep's serve. Crucial CRUCIAL game. Halep plays one long and it's advantage to Janko. Some very tense faces on Arthur Ashe. Jankovic - under intense pressure - plays a stunning rally and takes Halep to all corners of the court and Halep is officially having a strop. She hits the ground with her racquet several times and then swipes at her thigh with her hand. Has she missed her golden chance? She's red in the face and fuming. Can Janko keep the pressure on? I'll stop asking questions and get on with it...

1830: Keo lost the second set by the way 6-1. A third set decider for the Brit and Chan. Back to Janko.

1828: Listen up folks. We have a potential banana skin on our hands. Or rather Jankovic's. Halep is quite literally serving for the match. What a scalp this would be.

1824: A quick rundown of scores from the women's singles today. Patty Schnyder beats Kirsten Flipkens 6-1 6-3. Sofia Arvidsson beats Sorana Cirstea 6-1 6-2. Mirjana Lucic beats Alicia Molik 7-6 (7-5) 6-1. Alexandr Dulgheru (25th seed) beats Julie Coin 6-3 6-1. Anastasija Sevastova beats Regina Kulikova 6-0 2-0 (retired, lower back). Maria Jose Martinez Sanchez (22nd seed) beats Jamie Hampton 6-4 3-6 6-0. Aravane Rezai (18th seed) beats Magdalena Rybarikova 7-6 (7-5) 7-6 (9-7). Svetlana Kuznetsova (11th seed) beats Kimiko Date Krumm 6-2 4-6 6-1. Back to the action....

1821: You know the old saying - where there's a wobble, there's a wibble. Keo breaks back to get it to 1-4 in the second set. A temporary blip perhaps for the Londoner?

1817: I've dug out some Keo quotes she said about Chan yesterday. Might provide a bit of background to the battle as it hots up towards the end of the second set. Keo said: "Chan is ranked 77th in the world and she hits it hard and flat through the court. Although I have never played against her before I have practised quite a bit with her in the past and I've got a rough idea of what I've got to do to win the match."

1814: What have you guys done? I leave my desk for four minutes and I trusted you. I said strictly NO WOBBLES ALLOWED. Keothavong is 4-0 down with two breaks of service. I'm outraged at you all. Mmmm

1804: Janko's 2-1 up on serve in her decider against Halep, but Keo's having a wobble in the second set against Chan - the Chinese Taipei player has broken and is currently serving for a 3-0 lead.

Martyn in London, via text 81111: "Am working with one eye on the US Open live scores and your live text.... Great start from Anne.... Am nervously waiting for the inevitable wobble."
Thank you for your words Martyn. Welcome on board. It's a classic British reaction to anybody doing well - when's the wobble coming?! Let's all put our hands together and start believing. Repeat after me....Special K...Special K...Special K....Let's visualise Keo and Bally riding the streets of Manhattan in an open top double decker bus draped in a Union Jack flag. What a vision.

1756: Janko is doing it the hard way. She's been taken to a deciding set against Halep. Back to Louis Armstrong. (Sounded like an MC there)....The 16th seed Baghdatis seems to have got his act together against Clement and after losing the opening set, the Cypriot star wins the next two 6-2 6-1. Good recovery.

1751: Who knows how often the Union Jack flag will be unfurled this week but I'm giving it another waggle. Keothavong takes the first set 6-2 in a cool 30 minutes. What odds of a Keothavong and Baltacha final?

JZ, via text 81111: "I want anne keothavong to win like all brits but whos she playing? Someone called chan, does she have another name, where's she from, how good is she?"
Yung-Jan Chan is from Chinese Taipei. Current singles ranking is 76 and she celebrated her 21st birthday two weeks ago. What more could you possibly want? Oh - and according to the ITF website, she likes "music and the internet"

1745: Now my backside has found a new home and my ticker has stopped panting like an 83-year-old, I'm bang up for hearing your thoughts. Can Keothavong keep up her good start? All Muzza thoughts welcome. Anything tennis related. I want to hear from you. Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or 606.

1742: Keep an eye out for Court 16. An outside court yes, but Lukas Lacko is playing in the doubles. The name Lacko ring any bells? In around 24 hours, the Slovakian will be facing Andy Murray in their opening round of the men's singles.

1738: Jankovic steadies the ship with a service game and it's 4-1 in the second set. Next on Arthur Ashe is third ranked Novak Djokovic. Former champion Svetlana Kuznetsova is now one-set all against Date Krumm. A few nervy moments ahead for the 11th seed. Maria Sharapova also up shortly. Then later on we've got two players you may have heard of - Rafael Nadal and Caroline Wozniacki. The other Brit in action is Ross Hutchins in the doubles with Scott Lipsky on Court 15."

1731: Wave that flag. Keothavong is 3-1 up. The one break of serve so far. Good start for the Wimbledon-based star.

1723: Jankovic is having a stinker of a second set. She trails 3-0. Plenty to do for the fourth seed. Clement won the opening set 6-3 against Baghdatis but Baggy is storming back and looks set to take the second. Ding dong that one.

1715: Thank you again for your patience with the delay. What can you can do eh? I've jumped into my make-believe chopper and I'm scanning the courts at Flushing Meadows. Jankovic took the first set 6-4 but trails 0-2 in the second to Halep. Kuznetsova won the opener 6-2 against Date Krumm but trails 2-4 in the second. Keothavong has taken to the court 14 and WALLOP, she's broken Chan in the very first game. Nice start for the Brit. More in a sec.....just catching my breath.

1709: Half an hour later, the special escape squad (me and two others) have risked their lives and made it into another BBC building. I'm back up and running with limited access to information. Have I missed anything? Thank YOU for your patience.

1639: NEWS FLASH I'm not joking but we have a fire alert at BBC TVC. I have to evacuate. I will continue to be on twitter if possible. I will be back. Wish me luck.

1636: So where is everybody today? Stuck in the office getting a sneaky view of tennis updates away from the bosses? On public transport? In New York? I'd love to know where you're hanging out. Maybe you're in a park playing the great game. Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or get on 606.

1632: Jankovic looks in the mood today. The former finalist in NY a break up and serving at 2-0 against Romania's Halep. I have to say, I'm quite a fan of the purple number JJ is sporting today. Menacing yet stylish. Favourite tennis outfit? I never got to see Federer's dark blue suit he was rumoured to be preparing for last night's action.

1626: Sofia Arvidsson already two serve breaks up on Sorana Cirstea on Court 14. Keothavong had better start warming up. She's up next. Fancy Anne's chances today? Did you know her nickname is Annie or Special K?

christortise on Twitter: "Wozniacki-Dementieva final, taking 3 hours over 2 days, 7-6 6-7 10-8. Or something like that"
It's never too early for predictions. Dementieva looked smooth yesterday. Wozzo (?) swinging her glowing nails around under the lights later today.

kinsang on 606: "Have a feeling that Clement could upset Baghdatis."
These two boys have kicked off day two on Louis Armstrong. It's 1-1 with Clement looking good on his serve. You do mean 'beat' when you say 'upset'? Unless you think Clement could pile in with a stream of insults to cause a stream of tears from Baghdatis? Either way, I like your thinking.

1612: So who's in action? Let my colleague David Ornstein take you through today's action: "In the words of Alicia Keys, let's hear it for New York. Tuesday's headline acts are: The one they call JJ - women's fourth seed Jelena Jankovic - raises the curtain on Arthur Ashe Stadium at 1100 (1600 BST) and she is followed by the third-highest ranked man in the world, Novak Djokovic. Former champions Svetlana Kuznetsova and Maria Sharapova also strut their stuff, before the main evening attractions - Rafael Nadal and Caroline Wozniacki . There is even a dose of British interest as Anne Keothavong features in the second match on Court 14 and Ross Hutchins duets with Scott Lipsky in the men's doubles second on Court 15." Salivating over that feast of goodies?

1608: Of course, this live stuff would be nothing without you. Give me your blabberings. Predictions. Thoughts on Andy Murray's chances. Lookalikes. Nadal or Federer? Who are you looking out for today? Are you anywhere unusual? Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or get bantering on the 606 messageboard.

1604: WELCOME (capital letters have their place you know). After yesterday's feast of five-set marathons on Mammoth Monday we have Tantalising Tuesday that will hopefully evolve into Terrific or Tremendous Tuesday. Before you put that kettle on though, why not check out Elena Baltacha's fabulous column she bashed out after her first-round win against Petra Martic. A cracking read. Fellow Brit Anne Keothavong is playing in about an hour. More details on that and what else is coming up in a bit. Are we happy campers today?

1557: Day two. US Open. It doesn't matter that your football club have a few hours to sign that super-striker you've been dreaming about since the start of the season. The small bouncy balls at Flushing Meadows are what matter today. Are you on board or what?
