Roger Federer exits French Open after defeat by Stan Wawrinka

Roger Federer has bowed out of the French Open after a one-sided quarter-final defeat by fellow Swiss player Stanislas Wawrinka.

The second seed struggled to hold off his Davis Cup team-mate, suffering a 6-4 6-3 7-6 (7-4) defeat as Wawrinka advanced to the semi-finals for the first time.

In blustery conditions, Federer's smooth ground strokes lacked their usual precision, and he conceded a break in just the third game of the match.

This lapse was enough for Wawrinka to take a 1-0 lead and the eighth seed tightened his grip on the match, snatching another break in the second set to heap more pressure on the crowd favourite at Court Suzanne Lenglen.

Federer, for once, could not muster a masterful response and after falling two adrift he was forced to fight against elimination in the third set tie-break.

But a couple of close calls went against him, drawing noises of derision from the crowd, and a forehand volley from Wawrinka ended the 2009 champion's hopes of adding to his 17 Grand Slam titles.

Today was my best match on clay and it's an incredible moment for me.

Federer was gracious in defeat and admitted that Wawrinka handled the testing weather far better than him.

“We know Stan can do this and it's nice for him and important for him to string it together and do well," he said. "I thought he played really great tennis today.

"It was tough, so it's all the more impressive the way Stan was able to play."

Warwrinka, who will face Jo-Wilfried Tsonga in the last four, believes he produced one of the finest performances of his career.

"Today was my best match on clay and it's an incredible moment for me,” he said. “The conditions were difficult with a lot of wind but I believed in my game and it was a really incredible match from me.

"I'm playing good tennis and I'm really pleased to be in Paris semi-finals for first time."
