Top ranked Wozniacki eliminated from French Open.

Top-ranked Caroline Wozniacki will have to wait for her first major title after losing to Daniela Hantuchova 6-1, 6-3 Friday 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.

This 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. No. 2 Kim Clijsters lost Thursday.

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 advanced.
Sam Stosur is out of the French Open a lot earlier than she was last year.

Runner-up a year ago, the Australian was knocked out in the third round Friday, losing to Gisela Dulko of Argentina 6-4, 1-6, 6-3. The defeat came an hour after defending champion Francesca Schiavone advanced to the fourth round.

Stosur struggled early in dropping the first set, but came back and easily won the second. The 51st-ranked Dulko, though, regained control after breaking to take a 4-2 lead in the third, and held serve twice to close out the match.

Roger Federer had no such worries. The 2009 French Open champion had 10 aces and only 20 unforced errors in a 6-1, 6-4, 6-3 win over No. 29 Janko Tipsarevic.

Later Friday, Novak Djokovic was scheduled to put his perfect season on the line against 2009 U.S. Open champion Juan Martin del Potro. Top-seeded Caroline Wozniacki will also be back on court to play for a spot in the fourth round.

The eighth-seeded Stosur, who also reached the semifinals at Roland Garros in 2009, had 35 unforced errors in the match on Court Philippe Chatrier.

Dulko equaled her best Grand Slam result by reaching the fourth round. She also won three matches at the 2006 French Open and the 2009 U.S. Open.

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.

"I've been just sick for three or four days," Peng said, adding that she has had a fever. "So it's tough for me to play. I was really tired. I was really sick so my body could not really handle that."

Svetlana Kuznetsova, the 2009 French Open champion, advanced by beating Rebecca Marino of Canada 6-0, 6-4. And 10th-seeded Jelena Jankovic reached the fourth round with a 6-2, 6-2 win over Bethanie Mattek-Sands of the United States.
