That's it for now, check back later for updates on Ivanovic and Novak Djokovic among other things, then get some rest and prepare your excuses for Monday monday morning. Live text commentary on Andy Murray v Feliciano Lopez
will kick off on Sunday night at 2345 BST,
to give us a bit of build-up before the start of play just after midnight, when 5 live will join the fun. Straight sets, anyone? Thought not....
Hats are being prepared for consumption and trophies for award despite it being only day six, I'm looking forward to a Serena v Djokovic final already. Really, can anyone see Serena being upset over the next week? Next up for her will be Ana Ivanovic or Sloane Stephens. "I'm glad to be in the second week and I'm looking forward to my next match," says Serena. Cracking stuff.
Serena 6-1 7-6 (7-5) Azarenka
Serena wins a humdinger of a rally with a backhand down the line for 4-3 but Azarenka stands firm, a drop volley putting her 5-4 in front. Serena gets on top of a high bounce and slams a forehand winner for 5-5 and then hits an ace - no, Hawkeye shows it was well wide - but Azarenka nets a forehand on the next point. Match point number five
.... and Azarenka goes wide with a forehand. A terrific match in the end but the 28th seed beats the fourth seed.
SERENA WILLIAMS BEATS FOURTH SEED VICTORIA AZARENKA 6-1 7-6 (7-5) Serena 6-1 6-6 (3-3) Azarenka
Serena gets the first mini-break when Azarenka nets a forehand for 3-1 but a double-fault brings it back level at 3-3 at the changeover.
Serena 6-1 6-6 Azarenka *
A manual refresh will erase any suggestion that Azarenka has won 56 games, although she is doing rather well now. Serena stops the rot with a solid love hold, despite a double-fault at 40-0, and we're into a tie-break.
* Serena 6-1 5-6 Azarenka
It's in the balance at 30-30 and we're treated to a fantastic rally, with Azarenka dominating on her forehand at first before Serena turns it her way and takes it with a wrong-footing backhand. Break point
.... but the Azarenka forehand up the line works again, and she's able to live with Serena's pace at the moment. She holds after a couple of deuces and it's three games in a row.
Serena 6-1 5-5 Azarenka *
Drama. Serena hits an ugly backhand out on the first point and is in trouble in the second until Azarenka misses with a backhand of her own. It's 15-15, Serena hits her 10th ace and lets out another blood-curdling scream. Azarenka comes right back to make it 30-30 and there is a bit of tension out there for the first time this evening. Azarenka then moves in to put the pressure on but breaks a string, and the ball loops up perfectly for Serena to smack a forehand pass. Match point number four
..... and Serena chases down a ball in vain, ending in a perfect splits pose. Azarenka then hits a great return onto the baseline that Serena cannot control and it's break point
.... Ace! Have some of that. Another good Azarenka return gets her a second break point
.... Serena chases down a net cord and has the court at her mercy but fires it straight at Azarenka, who loops the ball back into the open court. What a game and what a superhuman effort from Azarenka. We press on....
* Serena 6-1 5-4 Azarenka
A sharp defensive backhand slice shows Serena's game is an good shape all around as she moves to 0-30, and she then races out wide to get back a forehand pretty much from the first row of the stands. Three match points
... and Azarenka saves the first with a rasping forehand of her own. Serena goes long with a forehand on the second, and looks to have won it on the third only for a forehand to be called wide. The American goes to Hawkeye but is defeated by modern technology and it's deuce. Azarenka earns a game point and takes it when Serena goes long, very impressive battling from the number four seed.
Serena 6-1 5-3 Azarenka *
Serena holds to 30 despite one ferocious Azarenka return and shows absolutely no sign of faltering. And for the one person concerned about my "nauseating chummying up to my favourite player", we refer to her as 'Serena' because at first sight 'Williams' could refer to either of two people, and it's about getting the key info - who's playing - across in the simplest fashion. And Boris Becker is still my favourite player.
* Serena 6-1 4-3 Azarenka
Avoid moonballing, kids. It made for some very tedious French Opens in the 1980s. An Azarenka drop shot almost sees Serena come a cropper with the net, but at 30-30 the Belarusian nets a forehand and it's break point
.... and Serena belts a huge forehand into the corner from behind the baseline. Another superb shot, and that could be that.
Serena 6-1 3-3 Azarenka *
Azarenka sweeps an off-forehand onto the sideline and Serena then nets a forehand to make it 15-30. A bit of cheeky moonballing from Azarenka does not disrupt Serena and she smashes her way back to 30-30 before taking the game with a running cross-court forehand and a scream from the very depths of whatever it is that makes us human. Terrifying.
* Serena 6-1 2-3 Azarenka
There's just the odd hint of frustration from Serena as she fails to make the breakthrough in this second set as easily as she did in the first. Azarenka reaches for an improvised volley at deuce and grabs the hold. Credit to the Belarusian, who's lashed herself to the mast and clung on to see out the storm, for now. That's a sailing metaphor.
Serena 6-1 2-2 Azarenka *
Azarenka gets some joy from a backhand return fired at Serena's feet for 30-30, and a forehand up the line then takes her to break point
.... but Azarenka clubs a forehand into the net. She needs to be going for these shots though. Serena slams the door shut with an ace out wide and takes the game.
* Serena 6-1 1-2 Azarenka
"C'mon!!!" Serena cracks a beauty of a forehand down the line for 15-15, her 19th winner of the day, but Azarenka holds firm and hits her first ace to move to 40-15, before swinging one out wide to convert game point.
Serena 6-1 1-1 Azarenka *
Azarenka takes a nasty tumble on the second point but doesn't take my advice and feign injury to get out of there as quickly as possible. She fights on. Serena holds to love.
Nicola from newcastle via text:
"Come on serena. Show the rest of the women in the draw who's boss."
* Serena 6-1 0-1 Azarenka
Azarenka gets a much-needed hold but only after Serena flicks one beautiful cross-court forehand at 40-15, and then hits through the same shot to make it deuce. A double-fault helps Serena to break point
but the fourth seed comes up with a good first serve to see it off. Moments later, the American has break point number two
but finds the net with a forehand when off balance, and Azarenka holds.* denotes NEXT to serve
Serena 6-1 Azarenka *
A comeback of sorts is building when Azarenka gets a break point
at 30-40 and she fires a good return into the corner, only for Serena to lunge to her right and hit a magnificent cross-court forehand winner. Follow that with an ace and a tracer of a backhand down the line - job done, first set in the bag.
* Serena 5-1 Azarenka
Serena is a blur of red as she smothers the net to thump away a volley on the opening point and Azarenka, reeling, follows up with a double fault. The Belarusian does well to scramble her way back to 30-30 and some forceful forehands earn her a game point, prompting a "Come on!" Azarenka plays another well constructed point and has Serena on the run, forcing the error and preventing me from using our magnificent 'bagel' graphic.
Serena 5-0 Azarenka *
A hint of pressure at 30-30? Not so much. Azarenka finds the net with a backhand but never has the prefix 'unforced' been more misleading when counting up errors.
* Serena 4-0 Azarenka
Serena swats away a second serve return and follows it up with a thumping drive volley for 15-30, before Azarenka goes long with a backhand. Two break points
.... Azarenka saves the first with a good forehand down the line, but Serena hits a screamer of a forehand on the second. Brilliant stuff.
Serena 3-0 Azarenka *
Oh my. You have to fear for Azarenka a little, and the rest of the field, as Serena wallops down three aces to take another service game. The chasm between the American, in terms of confidence and ruthlessness, and the rest of the women is undeniable. In fairness, most of the men would love to be able to serve like that too, averaging near 120mph.
* Serena 2-0 Azarenka
I should have said, please refresh your page manually to make the world a better place. Serena quickly earns two break points
at 15-40 and slightly overruns a short forehand on the first, only to batter a massive backhand return winner on the second.
A quick coverage update, Andy Murray v Feliciano Lopez
will start at 0000 BST on Monday and I'll be right here live texting, hopefully with some 5live commentary alongside. Check back for details before preapring for a late Sunday/early Monday rollercoaster ride.
Serena 1-0 Azarenka *
Serena holds serve to 15 as Azarenka goes for too much on the returns. It's a bit blustery out there this evening.* denotes NEXT to serve
Brad Gilbert on Twitter:
"Looking forward to seeing if Aza has anything to challenge SW. she might be the only player capable in the draw. bad luck draw for Aza."
Serena has a 5-1 lead-to-head record against Azarenka,
and three US Open titles in the bank, so despite the fact that the Belarusian should provide a real test there's not much doubt who the favourite is. Azarenka is decked out in bright blue and Serena, under that tracksuit top, in bright red, I think
Evening all. Ornstein has gone off in search of cold remedies, leaving himself in danger of missing the start of one of the matches of the first week. Serena Williams is making her way on to Ashe followed by fourth seed Azarenka - a match that could have been a semi-final if Serena were seeded closer to her true position in the game.
Next up for the 16-time Grand Slam champion is Juan Monaco or Tommy Haas. Federer remains in contention for a record sixth US Open title. Next up for us, Serena Williams v Victoria Azarenka
. For that one, I'll leave you in the expert hands of
ROGER FEDERER BEATS MARIN CILIC TO REACH ROUND FOUR OF THE US OPEN Federer 6-3 4-6 6-4 6-3 Cilic
Time for a spot of showboating. Delicious drop shop. Perfect ace out wide. Three match points
. Cilic nets a return. Federer reaches the last 16 for the 30th Grand Slam running. Quite an achievement, that.* denotes next server
*Federer 6-3 4-6 6-4 5-3 Cilic
Federer clearly wants to get this over and done with asap, hence the chip-and-charge tactics at 15-15. Unfortunately for the Swiss, Cilic is wise enough to belt a return straight at his body and then net does the rest. The reprieve is only temporary, however. A double-fault helps Federer to break point
and then comes another chip-and-charge. Roger seems in control, only for Cilic to dish up a juicy volley that his opponent can only turn into the net. A powerful forehand gives Federer a second break point
but Cilic uses Hawk Eye to prove a Roger forehand is long and then smashes his way to game point. He's soon back in trouble, though, after a limp forehand. Break point three
... rally ensues... Federer in charge... Cilic looking tired.... Federer nets a regulation forehand. The wind picks up just as Cilic winds up for a backhand. He nets. A fourth break point
. Federer not letting go of this game. He's pouncing on his prey. Cilic horribly shanks a forehand. Game, soon to be set and almost match.* denotes next server
Federer 6-3 4-6 6-4 4-2 Cilic*
And break back he almost does, engineering a break point
at 30-40. But Federer slams the door shut with a couple of monsters serves and, after clinching the game, he wows the crowd with a through-the-legs 'hot dog'. Talk of which is making me peckish.* denotes next server
*Federer 6-3 4-6 6-4 3-2 Cilic
Cilic responds with similar brutality to keep his hopes alive. This would be a super time to break back...* denotes next server
Federer 6-3 4-6 6-4 3-1 Cilic*
Federer is getting on a bit but I can't agree he's showing his age, Jim. At least not today. He gives Cilic to run-around with a brilliant hold to love. Still, not over just yet.* denotes next server
Jim, Glasgow, via text on 81111:
"Sorry but Federer is showing his age out there, I think another Grand Slam is way beyond him against the younger guys like Rafa and Novak."
*Federer 6-3 4-6 6-4 2-1 Cilic
A fourth double-fault of the day at 15-30... not the best timing. Two break points
. Both saved, the second with a blinding inside-out forehand winner. But an attempted repeat sails wide after Federer switches the pace, catching Cilic off guard. Break point three
... woeful forehand. Federer strikes. Could be curtains for Cilic now.* denotes next server
Federer 6-3 4-6 6-4 1-1 Cilic*
Reasonable opening for Cilic at 30-30 and it's chances like these that he needs to be taking. But twice the world number 28, who made round four of the Australian Open but fell in the first round at Roland Garros and Wimbledon, shoots long. Federer holds and continues to look reasonably fresh out there.* denotes next server
*Federer 6-3 4-6 6-4 0-1 Cilic
Ace number nine from the Cilic blade takes us to 40-15 and number 10 seals a commanding service hold. Still no sign of fatigue from either man, though both are more than a bit sweaty. Cilic's Brazil football kit-like outfit looks soaked through, but he's battling on.* denotes next server
A quick scoot around the grounds tells us that 10th seed Petkovic
leads Vinci 6-4 4-0 and eighth seed Fish
has just gone a break to the good against Anderson in set one.
Federer 6-3 4-6 6-4 Cilic*
Federer using various different languages to gee himself up between points. After belting his way to 30-0 it's "come on!" in German. Cilic brings it back to 30-30 but a booming serve down the middle takes Roger to set point before his opponent floats a forehand just long. Federer shakes his fist, Marin jogs off for a comfort break.* denotes next server
Richard, Bristol, via text on 81111:
"Federer sweating it out against Cilic. This boy has got game and will be a Grand Slam champion soon if he can sort his head out."
*Federer 6-3 4-6 5-4 Cilic
It's getting windy out there on Arthur Ashe Stadium and one particularly gust appears to knock Cilic out of his stride as Federer forces the Croat to net with a expertly-constructed point for 15-30. However, Federer then fails to pounce on a second serve and an ace of almost 140mph makes it 40-30. Federer lands a forehand bang on the baseline for deuce and when a shoulder-high forehand bullet stuns his opponent, it's break point
. Cilic is warned by the umpire for taking too long between points. He then throws down the most untimely of double-faults. Federer jogs back to his seat with a spring in his step. He's about to serve for the third set...* denotes next server
Federer 6-3 4-6 4-4 Cilic*
Someone in the crowd seems to be yelling instructions at Federer between games. A fan, I should add. Don't think there's much he can do better, though, as this hold to love illustrates. Sealed with a trademark forehand winner. Tasty.* denotes next server
byodun on Twitter:
"CILIC #youthfulness,power and sheer determination...FEDERER #finese,style and purposefulness. Who will come out TOPS?"
*Federer 6-3 4-6 3-4 Cilic
The net tape prevents Cilic Bang from holding to love but then comes to his aid to halt a Federer backhand in its tracks. The world number 28 keeps himself in a strong position. How he'd like a break of serve now...* denotes next server
Federer 6-3 4-6 3-3 Cilic*
A perfectly-timed crosscourt backhand and cleverly-disguised backhand drop shop help Federer reel off a comfortable hold. However, if anything Cilic looks to be growing in confidence and there's no signing of him flagging physically either. Nail-biter.* denotes next server
Over on Grandstand, 10th seed Andrea Petkovic (of Petko-dance fame) is broken when serving for the first set against Roberta Vinci. On Louis Armstrong, eighth seed Mardy Fish is just getting start against big-serving South African Kevin Anderson.
*Federer 6-3 4-6 2-3 Cilic
Point of the match by some distance to get us up and running in game five. No quarter asked or given from the baseline, nor at the net. Back, forward, back, forward, side-to-side, side-to-side. Looks as though Marin has it in the back but a rush of blood sees him make a complete hash of an attempted backhand pass. The Croat then nets for 15-30 and Federer looks good for the break. But a couple of poor forehands ruin his chance. "Arrrgggghhhh!!!" yells the world number three. Really should have pounced there.* denotes next server
Federer 6-3 4-6 2-2 Cilic*
A double-fault at 30-30 prompts a few more beads to drip from Federer's brow. He does, however, save the break point
and avert the danger when Cilic nets. And nets again. And then goes long. The players look nervous. The crowd sounds nervous. Even I'm nervous. Which way's this going to go, people?* denotes next server
*Federer 6-3 4-6 1-2 Cilic
Federer keeps his net-approach success rate above 70% with a cute volley for 30-40. Cilic comes out fighting from the baseline, though, and saves the break point
by when Federer miscues a return. The Swiss then nets and goes wide. Vital hold from the 22-year-old. Is that that sight of Federer sweating I see? I think it is, you know. Collectors item.* denotes next server
Federer 6-3 4-6 1-1 Cilic*
Advantage Federer? Think again. A first double-fault of the day from the 30-year-old gives Cilic 0-30. Federer attacks, hitting as deep as possible. Scampers into the net. Cilic goes for the backhand pass up the line... makes it! Three break-back points
and Federer can't control the Croat's power. Cilic strikes at the first time of asking and we're back on level terms.* denotes next server
*Federer 6-3 4-6 1-0 Cilic
Big trouble for Cilic as Federer moves to 30-40 and a break point
. The Croat survives with an audacious but wonderfully-executed backhand drop shot from the baseline. Just creeps over the net. He's not so fortunate with backhand drive moments later and that means a second break point
. Federer dictating the tempo, looking focused, oozing with confidence. Cilic runs round a forehand... connects well... but it clips the net. Advantage Federer.* denotes next server
So, both men have dropped their first sets of the tournament. With Cilic flying and Federer, well, Federer, I'm not even going to attempt to call this one. Your predictions are very much welcome, though. Keeps the
coming, ladies and gents.
Federer 6-3 4-6 Cilic*
A stunning backhand pass and unstoppable forehand winner see Cilic move to 15-30 and when Federer goes long, the Croat has two set points
. The first is saved when Roger forces Marin to lift a forehand beyond baseline, but Cilic is all over the five-time champion on the second... massive forehand out wide... Federer sprints across to the advantage court... defensive backhand... clips the net! Game well and truly on.* denotes next server
And Jelena Jankovic
bites the dust with a 6-4 6-4 defeat by 17th seed Anastasia Pavlyuchenkova
rosso_neri on Twitter:
"Fed has managed fine for years with few injuries. It's about players being clever with their own scheduling. Not over doing it. As well as playing style. The excessively grinding playing style many players have doesn't help them stay injury-free for long"
*Federer 6-3 4-5 Cilic
A stupendous 86mph backhand crosscourt pass gives Roger 15-30, but two errors from the Swiss put his opponent on top and Cilic moves to within a game of levelling the match.* denotes next server
Federer 6-3 4-4 Cilic*
An uncharacteristically sloppy backhand into the net from Federer gives Cilic hope at 30-30, but we can forgive him that. Normal service is resumed to make it 40-30 before Cilic goes long.* denotes next server
*Federer 6-3 3-4 Cilic
More of the same from Cilic Bang as he keeps his nose in front in set two. Another hold to 15 means the pressure swings back to Federer's racquet. Precious little to chose between them this set - looks like being decided by one or two crucial points or perhaps a tie-break.* denotes next server
Federer 6-3 3-3 Cilic*
Federer responds in kind and his rhythm has been a joy to behold so far. Elsewhere, seventh seed Francesca Schiavone
beats Chanelle Scheepers
5-7 7-6 (7-5) 6-3 and Anastasia Pavlyuchenkova
leads Jelena Jankovic
6-4 5-3. Looking like another Grand Slam disappointment for JJ.* denotes next server
*Federer 6-3 2-3 Cilic
Marked improvement from Cilic on serve in the last couple of games. Changing the pace well, plus cutting out the silly errors. Starting to play with far greater intelligence and composure. Holds to 15 to stay right in this second set. The Croat is on a five-match losing streak against top-three players - can he turn is around today? He beat Andy Murray en route to the Flushing Meadows quarter-finals in 2009, so he is capable of a shock...* denotes next server
Razer178 on Twitter:
"The ATP calendar is too busy. It's bad for the career longevity of the players, plus the fans who pay to watch."
Federer 6-3 2-2 Cilic*
For the first time since game three of the opening set, Cilic gets his chance. A forehand winner precedes a backhand pass for 0-30. Federer levels and lets out a little shout of "allez!". But the Swiss then nets a routine forehand to gift his opponent a break point
. Cilic then constructs a perfect point and has Federer on a string, only to belt an overhead into the net. WHAT A MISS. Federer scrambles out of trouble. How crucial might that missed opportunity prove?* denotes next server
*Federer 6-3 1-2 Cilic
Somewhat less classy, perhaps, but equally effective. Cilic holds to love and will now attempt once more to penetrate the Federer serve.* denotes next server
Federer 6-3 1-1 Cilic*
Or not... Federer gobbles up that game without giving his opponent a look-in. He really is a joy to watch, this guy - 11 winners, five unforced errors, a 65% first-serve percentage, a first-serve success rate of 77% and a second of 75%. Class. * denotes next server
*Federer 6-3 0-1 Cilic
Solid start to the second set by Cilic, holding to love after an early scare Time to make an impact on the Federer delivery.* denotes next server
On Grandstand, Schiavone

Federer 6-3 Cilic*
A terrifyingly quick ace down the middle gives Federer 30-15 and a forehand fired straight at his net-bound opponent makes it 40-15. The Swiss master takes the set with a whipped forehand that leaves his opposite number rooted to the baseline. First blood to Federer.* denotes next server
Andy Murray on Twitter:
"Is the 18th pull out in the us open telling the tennis authorities anything?? No?? Thought not..."
*Federer 5-3 Cilic
More splendid volleying from Cilic - that's certainly an area he seems to have been working on with coach Bob Brett. It's a case of anything you can do I can do better as Federer charges in for a volleyed pass of his own to make it 30-30, but Cilic fights his way through. Federer will now serve for the opening set.* denotes next server
Federer 5-2 Cilic*
A serving masterclass from Federer so far. The world number three wastes little time getting to 40-0 and, despite a superb Cilic volley for 40-15, he moves to within a game of the opening set with consummate ease. Gasps of admiration from the crowd.* denotes next server
*Federer 4-2 Cilic
Unforced error number 10 from Cilic (to Federer's three) brings up 30-30 and with a first-serve percentage of 44%, it's not looking too rosy for the 22-year-old. Two forehand winners help him home. He'll need a few more of them if he's going to have any chance today.* denotes next server
Federer 4-1 Cilic*
Intimidation tactics doing the trick for Federer just now. He blasts his way to 40-0 and despite a brief concentration lapse, seals the game when Cilic bashes a return long. Out on Court 17, 31st seed Marcel Granollers
retires while trailing 6-1 4-3 against Juan Carlos Ferrero
. That makes it a record-equalling 10 retirements in the men's draw. What's going on? Schiavone
on serve in the decider, Jankovic
on serve in the first.* denotes next server
*Federer 3-1 Cilic
A couple of delightful forehands take Federer to 15-30, at which point Cilic decides attack is the best form of defence. He does brilliantly with a couple of volleys but then dumps a third into the net. That's 15-40 and two break points
. The first is saved when Roger nets a backhand return, but Cilic fires long on the second. "Come ooooooonnnnn!" yells Federer. He's up an early break
.* denotes next server
Federer 2-1 Cilic*
Trouble on the cards for Federer as Cilic chops and changes the rally pace to baffle his illustrious opponent. When Federer nets a rushed forehand it's 0-40 and three break points
. However, Federer's experience and class come to the fore and the danger is averted with some dangerously deep hitting. A volley stops dead to give the 30-year-old game point, although Cilic batter a crosscourt forehand to take us back to deuce. An attempted pass from Cilic sails just long and the 22-year-old miscues a forehand return, breaking a string in the process, to send Federer over the line.* denotes next server
*Federer 1-1 Cilic
Cilic grants us a glimpse of the power at his disposal with a bludgeoned forehand winner for 40-30. Federer attacks his second serve and charges in to force an error for 40-30, but the Croat comes through with a well-executed one-two-punch.* denotes next server
Federer 1-0 Cilic*
A majestic hold to love for the 16-time Grand Slam champion. Shows plenty of aggression from the baseline and willingness to get into the net. A gorgeous pick-up takes him to 30-0 before Cilic goes long with a forehand and nets a backhand. Over on Grandstand, Schiavone
takes the second set against Scheepers on a tie-break. * denotes next server
Warm-ups under way... Federer in red top with matching bandana, black shorts, shocks and sneakers. An interesting yellow and blue shirt for Cilic, blue shorts, white socks and shorts. Federer, bidding for a record sixth US Open title, to get us under way.
As we await the arrival of Federer and Cilic on Arthur Ashe Stadium, a quick mention for Schiavone and Scheepers... Schiavone squanders a set point and they're into a tie-break. Over on Court 17, Juan Carlos Ferrero takes the first set against 31st seed Marcel Granollers 6-1.

"Great day of tennis at open. fed v cilic, tsonga v verdasco,serena v azarenka. fed, tsonga, serena all to win."
Federer and Cilic are meeting for the third time, Roger having taken the previous two in straight sets on the Parisian hard courts three years ago and the Monte Carlo clay earlier this year. Neither has dropped at set in the tournament so far - Federer brushing aside Santiago Giraldo and Dudi Sela, Cilic battling past Ryan Harrison and demolishing Wimbledon quarter-finalist Bernard Tomic.
Cometh the hour, cometh the man. Time for the Fed Express. I'll keep you posted on Schiavone, who saves a match point against Scheepers on Grandstand before breaking back for 7-5 5-5. And she holds for 7-5 5-6. Over on Louis Armstrong, 11th seed Jelena Jankovic is getting under way against Anastasia Pavlyuchenkova
Caroline Wozniacki beats Vania King 6-2 6-4 to reach round four of the US Open
Before all that, thought, time to tell you about world number one Caroline Wozniacki
... the Dane leads Vania King 6-2 5-4
on Arthur Ashe Stadium in the match preceding Federer v Cilic. We've already suffered one fairly major casualty today - ninth seed Tomas Berdych
retiring while trailing 6-4 5-0 against Janko Tipsarevic
. Meanwhile, 2010 French Open champion Francesca Schiavone
is on the verge of a straight-sets defeat by Chanelle Scheepers
