Paris, Jun 4 (EFE).- France's Jo-Wilfried Tsonga defeated Switzerland's Roger Federer 7-5, 6-3, 6-3 Tuesday in the quarterfinals of the French Open.
Tsonga, the No. 6 seed, needed just one hour and 51 minutes to finish off the second-seeded Federer, who won the title in Paris in 2009 and was a finalist four other times.
The Frenchman's opponent in the semifinals will be Spain's David Ferrer, who beat countryman Tommy Robredo 6-2, 6-1, 6-1.
Tsonga is trying to become the first Frenchman since Yannick Noah in 1983 to win at Roland Garros.
The last French player to make it to the semifinals at Roland Garros was Gael Monfils in 2008, while Henri Leconte was the last Frenchman to make the singles final back in 1988.
On the women's side, American world No. 1 Serena Williams defeated Russia's Svetlana Kuznetsova 6-1, 3-6, 6-3.
Williams will play Italy's Sara Errani in the semifinals.
Errani, who lost in the French Open final to Russia's Maria Sharapova last year, took out Poland's Agnieszka Radwanska, the world No. 4, 6-4, 7-6 (8-6) in one hour and 48 minutes.
The French Open is the second Grand Slam event of the tennis season and the only one played on red clay, the game's slowest surface.
