Stanislas Wawrinka says he produced one of the best performances of his career when defeating Roger Federer in the quarter-finals of the French Open.

Wawrinka coped with the blustery conditions much better than his fellow Swiss to book his place in the semi-finals with a 6-4 6-3 7-6 (7-4) victory.

Wawrinka will now face Jo-Wilfried Tsonga in the last four and could not be happier with his performance as he brushed aside the number two seed.

“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.”

Meanwhile, Federer was very gracious in defeat and conceded that Wawrinka was the better player on the day and deserved to go through.

“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.”

Wawrinka, who has made the semi-finals for the first time in his career in Paris, is now priced at 6.00 to go all the way and win the French Open.

His opponent in the semi-finals, Jo-Wilfried Tsonga is priced at 15.00, while Novak Djokovic remains the 1.75 tournament favourite.
