Rafael Nadal & Roger Federer advance at French Open

Rafael Nadal and Roger Federer both won at Roland Garros on Friday to keep their French Open hopes alive.

Seven-time champion Nadal recovered from losing the first set to beat Slovakia's Martin Klizan and reach the third round.

Federer, winner in 2009, blitzed Julien Benneteau to reach the fourth round.

Women's top seed Serena Williams and defending champion Maria Sharapova had easy wins, but Britain's Jamie Murray is out of the men's doubles.

Court Philippe Chatrier

Marion Bartoli (Fra) [13] beat Mariana Duque-Marino (Col) 7-6 (7-5) 7-5

Maria Sharapova (Rus) [2] bt Eugenie Bouchard (Can) 6-2 6-4

Sharapova led 6-2 4-2 when the match was suspended because of rain on Thursday and wrapped up victory in 15 minutes on Friday.

But it was a promising first Grand Slam tournament for 19-year-old Bouchard, from Quebec, who won the Wimbledon girls' singles title last year.

The defending champion, who made 28 unforced errors, now plays China's Jie Zheng for a place in the last 16.

Roger Federer (Swi) [2] bt Julien Benneteau (Fra) [30] 6-3 6-4 7-5

The pair had met six times before with Benneteau winning twice, including earlier this year in Rotterdam.

Benneteau also led Federer by two sets to love in the third round of Wimbledon last year only for the eventual champion to fight back and win in five.

Benneteau, who was struggling with a groin injury, broke serve in the first game but Federer won six of the next seven games and went on to win in an hour and 31 minutes. The Swiss plays either Gilles Simon or Sam Querrey next.

"I thought it was a different match than what we usually play against each other. He was clearly handicapped with the leg, which I was able to take advantage of," said Federer.

Federer, the 2009 French Open champion, added: "I'm happy because I have not used much of my energy so far. I feel totally relaxed. Mentally, I'm OK. I'm quite confident."

Jo-Wilfried Tsonga (Fra) [6] bt Jeremy Chardy (Fra) [25] 6-1 6-2 7-5

Ana Ivanovic (Ser) [14] bt Virginie Razzano (Fra) 6-3 6-2

Court Suzanne Lenglen

Rafael Nadal (Spa) [3] bt Martin Klizan (Svk) 4-6 6-3 6-3 6-3

Before this year, Nadal had lost only 14 sets in 53 matches at the French Open but he has lost the opening set in each of the first two rounds in 2013.

Nadal lost serve four times against Klizan and needed nearly three hours to prevail. The Spaniard, who has won six titles since returning from injury in February, plays Italy's Fabio Fognini next.

"I started a bit too defensive," he said. "I improved a little bit during the match."

Serena Williams (US) [1] bt Sorana Cirstea (Rom) [26] 6-0 6-2

Williams extended her winning streak to 27 matches and it was eight games and 33 minutes before Cirstea won a game.

Williams, who won her only Roland Garros title in 2002, will play Czech Petra Cetkovska or Italy's Roberta Vinci in the fourth round.

"I play very aggressive,'' said Williams. "That's important for me, because I want to keep on winning here.''

Tommy Robredo (Spa) [32] bt Gael Monfils (Fra) 2-6 6-7 (5-7) 6-2 7-6 (7-3) 6-2

Robredo now faces fellow Spaniard Nicolas Almagro

BBC Radio 5 live's Russell Fuller: "When the pain of defeat, and of playing 14 sets in six days wears off, Monfils may be pained by the four match points he had in the fourth set. He squandered one with an ill-advised drop shot, but this was also the story of a sterling comeback by Robredo. His opponent may have been tiring and gifting him a few freebies as the match wore on, but the Spaniard played a very streetwise and high quality match to leave him just one win away from a fifth Roland Garros quarter-final."

Agnieszka Radwanska (Pol) [4] bt Dinah Pfizenmaier (Ger) 6-3 6-4

Outside courts

David Ferrer (Spa) [4] bt Feliciano Lopez (Spa) 6-1 7-5 6-4

Richard Gasquet (Fra) [7] bt Michal Przysiezny (Pol) 6-3 6-3 6-0

Janko Tipsarevic (Ser) [8] bt Fernando Verdasco (Spa) 7-6 (7-3) 6-1 3-6 5-7 8-6

John Isner (US) [19] bt Ryan Harrison (US) 5-7 6-7 (7-9) 6-3 6-1 8-6

Isner soothed the memory of his record-breaking loss at last year's French Open with victory in another five-set epic on Friday.

A year to the day that he lost to Paul-Henri Mathieu in a 76-game battle, the most ever played in a men's match at Roland Garros, Isner won in three hours and 50 minutes.

Isner, who faces Tommy Haas next, holds the record for the longest match in history, his victory over France's Nicolas Mahut at Wimbledon in 2010. The match lasted 11 hours and five minutes.

Murray out

Juan Sebastian Cabal (Col) and Robert Farah (Col) bt Jamie Murray (GB) and John Peers (Aus) 3-6 6-4 6-4

"It's hard one to take. For pretty much the whole match we were ahead and then we let it slip away," said Murray.

"We didn't really do ourselves justice at the end, so we lost. But we played a lot of good stuff in both the matches we played, put in two good team performances."

Quotes of the day

"I think it's not that much fun to listen to those guys' press conferences but they say something controversial and they get slammed. So why would they want the stress of that?" Jamie Murray, when asked if he agreed with Ernests Gulbis's assertion that the top four, including brother Andy, are "boring".

"I'm not angry. I just think it's not fair. I'm not angry. I am a positive person, generally speaking." Rafael Nadal trying his best not to sound angry about the French Open scheduling.

"It's not about the celebrity. It's just about doing what I can do, and anything else that comes with it is a bonus. I'm just a regular old person that lives with my sister." World number one and 15-time Grand Slam champion Serena Williams.

"I'm not going shopping because I'm not allowed to ... I'm not allowed to cuddle either because it's energy-sapping. There's not much I'm allowed to do so I'm going to practice." Jo-Wilfried Tsonga on what he will do with his day off.
