French Open 2012: day seven as it happened 18.52 Wozniacki breaks Kanepi after turning the game in her favour at deuce, before taking a love game to trail 4-5 in the second set. She's not done yet. 18.47 Wozniacki is getting a drubbing at the hands of Kanepi - she's 6-1, 5-2 down. Schwank claws back a game but Nadal leads 3-2. 18.39 Nadal breaks Schwank and holds serve to lead 3-1 as Schwank toys with the crowd, encouraging them to spur him on. He knows it can't be long now. 18.29 Both Schwank and Nadal hold serve to draw level at 1-1 in the third set. Meanwhile Kaia Kanepi and Wozniacki have started on Suzanne Lenglen, and Kanepi leads 6-1, 3-1. Monaco and Raonic continue their long battle into the third set, with Monaco leading 6-7 (5-7), 6-3, 6-6 (5-5), 4-2. 18.19 Schwank is having a very fine turn on the court all of a sudden, charging the net and playing the ball low so the Spaniard can't return it. He's switched up his game and is showing some innovative approaches - a drop shot return from Nadal's serve, for instance. But it's Nadal who takes the second set 6-3. 18.13 Nadal grimaces as he drives a ball into the net, allowing Schwank to advance to 30-all and then 40-30. Nadal levels but fails to take the advantage, losing the break point and letting Schwank win the game. 5-3 to Nadal. 18.01 Nadal is up 4-2 as he closes in on the second set. He may be ruthlessly pummelling Schwank on the clay, but off court the man is impeccably polite. This prank call by a French radio station - who rang him on Tuesday ahead of his match - sees Nadal at his loveliest and most patient in the face of baffling idiocy: 17.51 Raonic clinches the tie breaker to take a two sets to one lead, in what may well have been the pivotal moment in the match. 17.49 Nadal 2-0 up already in a second set that nobody seems to be getting much out of. Juan Monaco and Milos Raonic, meanwhile, have locked horns in a battle for the third set that's gone to a nail-biting tie break. It's Monaco 6-7, 6-3, 6-6 (5-5) Raonic. 17.38 First set to Nadal 6-1, and we know it's not his birthday until tomorrow, but around the world where it's already June 3 the birthday wishes are pouring in... 17.28 Schwank denies Nadal a third consecutive break, pulling a game back. Nadal wastes no time on his serve, however, taking the following game to lead 5-1. 17.18 A bump in the road for Nadal as Schwank takes him all the way to break point before the Spaniard regains his composure. It's disrupted Nadal's rhythm, even if it won't stop him taking the set. Nadal 4-0 Schwank. 17.09 So Gasquet will face Murray next in the round of 16. Nadal now 3-0 up 22 minutes in after an efficient run on the clay. And here's Murray's winning rally against Giraldo today: 16.56 Nadal up another game, steaming ahead 2-0. Gasquet has just beaten Haas to the jubilation of the crowd to win 6-7, 6-3, 6-0, 6-0. 16.51 Schwank is serving. He takes the first point but not the first game after Nadal breaks him straightaway. Schwank, it's worth pointing out, has never made it to the fourth round of a major before. 16.39 Nadal on the clay now at Philippe Chatrier, while Richard Gasquet is on great form against Tommy Haas. He leads 6-7, 6-3, 6-0, 2-0. And here's Sharapova looking fierce: 16.29 Next up on that court we have Nadal v Eduardo Schwank. I think it's safe to say we're expecting Nadal to take this one as the number two seed meets the number 192 seed. Saturday's match against Nadal will be just the second third round Grand Slam appearance of the Argentine's career. Ladbrokes have Schwank at 200/1 to win in straight sets. 16.18 And Sharapova has beaten Peng 6-2, 6-1. Another blitz of a performance from the Russian who is on merciless form. 16.16 Lots of love for Murray's performance on Twitter and beyond: 16.06 Sharapova making light work of Peng - she's 4-0 up in the second set. Here's Murray, rightly pleased with his performance today: 15.56 Giraldo outclassed by Murray's confident, classy play today. He's on great form. Let's catch up on the results from elsewhere: Maria Sharapova 6-2, 2-0 Shuai Peng Juan Monaco 6-6 Milos Raonic Tommy Haas 7-6 (7-3), 2-4 Richard Gasquet Janko Tipsarevic beat Julien Benneteau Nicolas Almagro beat Leonaro Mayer Na Li beat Christina McHale Petra Kvitova beat Nina Bratchikova Murray 6-3, 6-4, 6-4 Giraldo Another love game would have been a nice way to end this, but Giraldo fights to the end. Still, he knows there's no stopping Murray, who wins the match to go through to the fourth round. Murray 6-3, 6-4, 5-4 Giraldo* Did Murray clutch his back for a moment there? Even so, there's surely not long to go now for the Scot who bides his time as Giraldo holds his serve. Murray 6-3, 6-4, 5-3 Giraldo A clinical finish for the Scot in another love game as he moves to secure the match. Murray 6-3, 6-4, 4-3 Giraldo* Giraldo's charging the net and playing gracefully but Murray's dug himself in and his defensive play is grinding down the Colombian. He waits for Giraldo to make an error, then another, breaking the Colombian once again. Murray 6-3, 6-4, 3-3 Giraldo Another love game for Murray - his third - with an ace from the Scot. Murray 6-3, 6-4, 2-3 Giraldo* The players ebbing a little as the heat takes it toll. Murray lets this one slip away without apparently looking for a break, with Giraldo launching some impressive returns Murray 6-3, 6-4, 2-2 Giraldo Giraldo swipes at the ball angrily as Murray advances, taking one, two points off the Scot as he stands on the brink of the game. Murray won't let him any further though. Murray 6-3, 6-4, 1-2 Giraldo* No signs of a struggle this time - Murray manages to score a single point off Giraldo but he can't stop the Colombian taking the game with relative ease. Murray 6-3, 6-4, 1-1 Giraldo Murray notches up his third love game as a tired Giraldo lets the ball breeze past. Murray 6-3, 6-4, 0-1 Giraldo* A 29-shot rally opens the third set, and it's safe to say Andy Murray's back is definitely not slowing him down. He is hammering the ball, bounding around the court like a gazelle. Murray stakes out his opponent with some skillful defensive play, waiting. Giraldo takes the advantage six times before he can finally claim the point - a marathon game for the pair. Murray 6-3, 6-4 Giraldo Great play from Giraldo as he thwarts Murray with a drop shot planted just beyond the net to win the first point. It sets the pattern for a game of gruelling rallies. Giraldo fails to return an easy second serve, but some deft play sees him arrive at break point. Another mistake from the Colombian and the game moves to deuce. Murray is first to steal the advantage, and when Giraldo pounds it into the net he seals his fate. Murray 6-3, 5-4 Giraldo* A point down, Giraldo scuffs the ground with his racket in frustration. He launches a counter-attack, keeping Murray at bay as he levels to deuce and then denying him the break point. Murray 6-3, 5-3 Giraldo So long as Murray keeps hitting them so deep, Giraldo is going to struggle to turn things in his favour. Another straightforward game for the Scot, as he plays for his second set one hour in. Murray 6-3, 4-3 Giraldo* A lovely backhand slice from Giraldo wrong-foots Murray and he follows it up with a brisk serve to take the game. Murray 6-3, 4-2 Giraldo Murray is practically stationary for a couple of points as he blasts the ball to the far corners of the court, leaving Giraldo helpless to turn things in his favour. Another ace and a screaming cross-court forehand clinch the game. Murray 6-3, 3-2 Giraldo* Murray at break point again and Giraldo manages to stave him off just once, with a long down-the-line forehand. The Scot pings the Colombian around the court like a pinball, taking the point. Murray 6-3, 2-2 Giraldo Giraldo threatens to break Murray but the Scot pulls it back - 2-2. Murray 6-3, 1-2 Giraldo* Giraldo's turn for a love game as he sends Murray reeling across the court. The two are showing no sign of slowing down either. Murray 6-3, 1-1 Giraldo Now Murray's really showing his back's in good working order - FOUR aces in a row, at blistering pace. Murray 6-3, 0-1 Giraldo* Even Murray has to congratulate Giraldo on his return with a little "Yup" after he charges the net to retrieve a drop shot from the Scot. The Colombian playing with a little more head and a little less beef as he takes the first game of the second set. Murray 6-3 Giraldo A punchy forehand, a powerful serve and Murray's bobbing and weaving across the clay with panache. He takes the first set on fine form. Murray 5-3 Giraldo* A powerful backhand down the line from the Scot can't stop Giraldo pulling back another game in a swift set - just 26 minutes gone. Murray 5-2 Giraldo Two love games in a row as Murray looks determined to make another swift despatch of the opponent he trounced 6-1, 6-2 in April. It's a compelling, brisk performance from the Scot. Murray 4-2 Giraldo* Two punishing rallies see Murray turn the point in his favour, forcing Giraldo on the back foot. At break point, the Scot's looking strong, and Giraldo crumbles to give Murray the first break. Murray 3-2 Giraldo Strong baseline play from both players. If it's a strain on Murray's back, he isn't showing it, stealing a love game off the Colombian. Murray 2-2 Giraldo* An ace for Giraldo to match Murray's as he holds serve to 40-0. Murray pulls back a point, but he can't stop Giraldo from taking the game. Murray 2-1 Giraldo Encouraging start for Murray as he holds serve again - and he's looking nimble as a gazelle out there. Murray 1-1 Giraldo* Giraldo replies with a confident series of baseline shots to level things up. Murray 1-0 Giraldo Murray kicks things off with an ace, securing the opener with relative ease. 13.38 Murray has played Giraldo once before, in Barcelona this April where he beat him 6-1, 6-2. Here's a highlights reel: 13.30 Murray due on Court 1 soon... 13.24 Li Na crestfallen as she makes yet another unforced error, burying an easy smash into the net. She leads the second set 4-2, but looks uncomfortable. 13.18 If you've just dropped in and are looking for Murray, he may be on soon. In the preceding match Lepchenko and Schiavone locked horns, with Lepchenko finally taking the third set after a 13-game slog. Lepchenko wins 3-6, 6-3, 8-6. 13.06 Obviously, photos are great and everything, and having access to a live web broadcast is very 21st century. But I think we can all agree that what Wimbledon really needs is a French-speaking impressionist painter to document the action: via @RacquetRequired. Like it? Tweet me @benbryant 13.00 Li Na looked like she was taking control for a moment, but fades as McHale bears down with a flurry of solid shots. McHale takes the first set 6-3. 12.53 Li Na muttering under her breath as she faces a crucial break point at 2-4 down. She fluffs it, making a meal of an easy forehand, but a moment later takes the opportunity to redeem herself with a pair of controlled strikes worthy of the defending champion. Li Na 3-4 McHale. 12.45 Interesting observation from Matt Cronin: 12.38 It's looking increasingly likely that Murray won't be on court for a while as Schiavone and Lepchenko slug it out with two sets apiece and three games each in the third set. Li Na is making heavy work of opponent McHale, struggling with her serve and offering herself words of reassurance. She's made a lot of unforced errors - 14 in six games. Li Na 2-3 McHale. 12.28 Youzhny's frustration wasn't just etched across his face in his match against Ferrer - here he is writing 'sorry' in the clay with his feet. 12.18 The sun's blazing down at Suzanne Lenglen and defending champion Li Na's off to a shaky start against 35-seeded Christina McHale - she trails 0-1. Women's fourth seed Kvitova breezed through her last set to beat Bratchikova 6-2 4-6 6-1. 12.08 Lepchenko steals the second set from 14-seeded Schiavone over on Court 1 - looks like we won't be seeing Murray just yet after all. It's Schiavone 6-3, 3-6 Lepchenko. 11.53 Youzhny finally yields to Ferrer in what has been a frustrating and disappointing game for the Russian. Ferrer wins in straight sets 6-0, 6-2, 6-2. Meanwhile, on Philippe Chatrier, Kvitova and Bratchikova have a set apiece and the Czech leads 4-1 in the third. 11.45 Our man in Paris Simon Briggs has served up his preview of the Murray-Giraldo game. He writes: If he experiences any repeat of the immobilising back spasms he suffered on Wednesday, it is hard to imagine that Giraldo will let him off as easily as Jarkko Nieminen did. 11.40 Over on Court 1, where Murray will play next, it's Schiavone 6-3, 2-3 Lepchenko. Ferrer leads Youzhny 3-2. The Russian's winning the support of the crowd, if nothing else, with a booming "Come on!" that's followed by a roar of appreciation. 11.29 Looks like a comeback may not be on the cards after all. Ferrer leads 3-1 and looks set for a straight sets victory. Here's the video I was looking for - Youzhny's 2008 tantrum where he smashed the racket against his head until he was bleeding. Just a bruised ego for the Russian this time, though. 11.19 Ferrer takes the second set 6-2, but there's an opportunity now for Youzhny to pull one back as he starts to find his form. Murray's looking very sprightly ahead of his game: 11.10 Schiavone takes her first set 6-3 over Lepchenko and, if she takes the second as expected, Murray may be on court in 30-40 minutes. Youzhny, meanwhile, leaves the court for a five minute break to regroup and recover. 11.03 Youzhny's poor performance continues to baffle, but he may be finding his feet as he takes his second game and denies Ferrer another break point. The turning point was a rally where the Russian rushed forward and forced Ferrer to scoop a drop shot limply over the net, which Youzhny promptly pummelled down court. Ferrer leads 5-2. 10.54 Kvitova's taken her first set against Bratchikova 6-2, while Ferrer's thrashing of Youzhny continues. He's leading 6-0, 5-1 now. Here's Ferrer precision engineering a backhand: 45 Youzhny pulls one back to cheers from the crowd as Ferrer leads 6-0, 3-1. Let's talk about tennis players on Twitter. They've been bandied about a lot this week. USA Today ran this piece on players fleeing the social network, and Maria Sharapova explained her reluctance to join Twitter at a press conference: "I can't even imagine what it would be like if I would tweet constantly," she said. So who are your favourites? I quite like Azarenka, personally, who tweets in three or four different languages I don't understand and occasionally comes out with stream-of-consciousness gems like this: Sublime. 10.35 Ferrer takes the first set 6-0 and the next game. Hope Youzhny has a big bag of rackets because he's looking twitchy... 10.30 Tantrum from Youzhny, who punches his racket into the ground after losing the next game. It breaks, so he hurls it into the stands where an audience member with quick reflexes catches it, just managing to avoid getting clobbered. He gets a warning for that, then goes on to lose another break point to go 5-0 down. 10.24 Ferrer pacing around impatiently as he holds serve, then takes another break point to lead 3-0. Meanwhile Paul-Henri Mathieu is alive and already back on the court after winning the second-longest match in French Open history on Thursday... 10.15 Ferrer and Youzhny have just made a start on Suzanne Lenglen. Ferrer is wasting no time with an early break against the Russian - he leads 1-0. 09.55 If you're wondering when Murray hits the clay today, he's second on at Court 1, so be sure to keep an eye on the live blog from around midday if you don't want to miss him. Here's the lineup for the first games this morning: Nina Bratchikova v Petra Kvitova David Ferrer v Mikhail Youzhny Francesca Schiavone v Varvara Lepchenko 09.45 Morning one and all, and welcome to our live coverage of day seven at Roland Garros. Yesterday proved to be relatively drama-free in a week that's included Serena Wiliiams's shock first-round exit and Andy Murray's back problems. Federer lumbered to victory against Nicolas Mahut, taking a full two-and-a-half hours to finish the Frenchman. Djokovic and Sharapova, meanwhile, devoured their opponents in straight sets. The question on everyone's lips today is whether Murray's back will hold out against Colombia's 50-seeded Santiago Giraldo. After pushing through the pain in his game against Jarkko Nieminen on Thursday, Murray hit back at his opponent - and later Virginia Wade's 'drama queen' jibe - but he's going to need to move a little less like a mannequin if he wants to win today. This is what he had to say about it after the Nieminen game: I just kind of gritted my teeth and tried to find a way of turning the match around because I was a few points probably from stopping around the middle of the second set.
