Federer and Schiavone advance; Stosur falls; Djokovic-Del Potro match suspended PARIS: Top-ranked Caroline Wozniacki's quest for a first major title was derailed Friday when she was beaten by Daniela Hantuchova 6-1, 6-3 in the third round of the French Open. The Dane has been No. 1 in the WTA rankings for almost the entire season but never really challenged her Slovak opponent on Court Suzanne Lenglen, having her serve broken five times. Following No. 2 Kim Clijsters' loss Thursday, it is the first time in the Open era that the top two seeded women failed to make the round of 16 at a Grand Slam tournament. Sam Stosur, last year's French Open runner-up, was also eliminated, but 2010 champion Francesca Schiavone advanced to the fourth round. On the men's side, 16-time Grand Slam champion Roger Federer had 10 aces and only 20 unforced errors in a 6-1, 6-4, 6-3 win over No. 29 Janko Tipsarevic. Novak Djokovic put his perfect season on the line against 2009 US Open champion Juan Martin del Potro, but the match was suspended because of darkness. Djokovic won the first set but Del Potro took the second, leaving the score at 6-3, 3-6. Wozniacki came into the French Open after winning the clay-court title at the Brussels Open. During the final, she called for a trainer and had her left thigh bandaged. Although she played the first two rounds at Roland Garros with the same thigh bandaged, she was not wearing any protection on her leg Friday. But injured or not, the Grand Slam drought remains — even though Wozniacki said she is not concerned with what others think. Hantuchova beat a current No. 1 player for the first time in her career after six previous losses, including one against Wozniacki this season. Federer, who won the French Open two years ago to complete a career Grand Slam, again had his serve working, landing 67 percent of his first serves and winning 84 percent of those points. Seventh-seeded David Ferrer also won, beating No. 31 Sergiy Stakhovsky of Ukraine 6-1, 6-1, 6-3. No. 9 Gael Monfils of France and No. 13 Richard Gasquet of France also advanced, while Albert Montanes of Spain defeated No. 12 Mikhail Youzhny of Russia 6-1, 7-6 (0), 6-1 and Fabio Fognini of Italy beat No. 30 Guillermo Garcia-Lopez of Spain 4-6, 6-3, 6-3, 6-1. No. 14 Stanislas Wawrinka of Switzerland came back from two sets down to beat No. 17 Jo-Wilfried Tsonga of France 4-6, 6-7 (3), 7-6 (5), 6-2, 6-3. Stosur was knocked out by Gisela Dulko of Argentina 6-4, 1-6, 6-3. The eighth-seeded Australian struggled early but easily won the second set to take back control. The 51st-ranked Dulko then put herself back in the match by breaking to take a 4-2 lead in the third. She then held twice to advance. Schiavone was broken at the beginning of her match, but then won five straight games to take the first set and eventually the match when opponent Peng Shuai of China retired while trailing 6-3, 1-2. Peng called for a doctor after the first game of the second set and had her blood pressure checked. She looked exhausted in her chair and then started to cry but broke for a 2-0 lead. Schiavone won the next game before her opponent quit. Svetlana Kuznetsova, the 2009 French Open champion, advanced by beating Rebecca Marino of Canada 6-0, 6-4. No. 10 Jelena Jankovic reached the fourth round with a 6-2, 6-2 win over Bethanie Mattek-Sands of the United States, while No. 11 Marion Bartoli of France, a former Wimbledon finalist, defeated No. 17 Julia Goerges of Germany 3-6, 6-2, 6-4. Two other Russians also advanced, No. 3 Vera Zvonareva and No. 14 Anastasia Pavlyuchenkova.
