Women's top seed and world number one Amelie Mauresmo of France has crashed out of the French Open tennis tournament once again, while men's number-one Roger Federer of Switzerland advanced to the quarterfinals in Paris.
Mauresmo, who has never gotten beyond the quarter-finals in 12 attempts at Roland Garros, lost Sunday's fourth-round match to 17-year-old Nicole Vaidisova of the Czech Republic, 6-7, 6-1, 6-2.
Meanwhile, Federer stayed on course to become just the sixth man in history to win all four Grand Slam tennis titles, as he eased past number 20 Tomas Berdych of the Czech Republic, 6-3, 6-2, 6-3. That set up a round-of-eight match against 12th-seeded Mario Ancic of Croatia, who upset number seven Tommy Robredo of Spain in five sets (6-4, 4-6, 2-6, 6-4, 7-5).
Third-seeded David Nalbandian of Argentina reached the quarterfinals with a 6-4, 6-4, 6-4 win over compatriot Martin Vassallo Arguello, while number six Russian Nikolay Davydenko beat 2004 champion Gaston Gaudio of Argentina, 6-3, 6-4, 3-6, 6-3.
Earlier, in third-round play, fourth-seeded Croatian Ivan Ljubicic battled back from two sets down to beat Juan Monaco of Argentina, 4-6, 5-7, 6-3, 6-4, 6-2. Number 25 Gael Monfils of France also needed five sets as he upset eighth-seeded American James Blake (6-2, 6-7, 7-6, 5-7, 6-4).
In the women's draw, fifth-seeded defending champion Justine Henin-Hardenne of Belgium topped number 10 Anastasia Myskina of Russia, 6-1, 6-4 while second-seeded Belgian Kim Clijsters topped number 15 Daniela Hantuchova of Slovakia, 6-1, 6-4.
In other fourth-round matches, 11th-seeded American Venus Williams surprised number seven Patty Schnyder of Switzerland, 4-6, 6-3, 6-2. Number 14 Dinara Safina surprised fellow-Russian Maria Sharapova, 7-5, 2-6, 7-5. That sets up a quarterfinal matchup against eighth-seeded countrywoman Svetlana Kuznetsova, who beat number nine Francesca Schiavone of Italy, 1-6, 6-4, 6-4.
Play was suspended in the final match of the day with 12th-seeded Martina Hingis of Switzerland and Shahar Peer of Israel tied at one set apiece (6-3, 2-6).
