Tommy Haas continued his resurgence with a straight-set rout of Mikhail Youzhny to start Monday's fourth-round men's action at the French Open.

Haas cruised to a 6-1, 6-1, 6-3 victory in just 90 minutes to reach the quarterfinals at Roland Garros for the first time. He has been to at least the round of eight in each of the other three Grand Slams.

In addition, the 35-year-old German became the oldest quarterfinalist in a major since Andre Agassi at the 2005 U.S. Open and became the oldest French Open quarterfinalist since a 39-year-old Istvan Gulyas in 1971. He is also the first German in the French quarters since Michael Stich and Bernd Karbacher in 1996.

The 12th-seeded Haas needed 13 match points to finally finish off John Isner in the third round, but had little trouble against Youzhny. The Russian beat Haas in the first round of the Italian Masters last month and took the first game on Monday, then proceeded to lose 10 straight on his way to a quick exit.

Haas, a winner in Munich last month, will play the winner between top-seeded Novak Djokovic and fellow German Philipp Kohlschreiber in the quarterfinals. He beat Kohlschreiber in the Munich final.

Two other men's fourth-round matches are on Monday's schedule, as seven-time champion Rafael Nadal will face Japan's Kei Nishikori and seventh-seeded French favorite Richard Gasquet will meet ninth-seeded Stanislas Wawrinka.

The first two quarterfinals were set Sunday. Roger Federer rallied past Gilles Simon in a five-set thriller and will play Frenchman Jo-Wilfried Tsonga, while a battle of Spaniards will pit David Ferrer against Tommy Robredo, who on Sunday rallied from a two-set deficit for the third straight match.
