Injured Petrova Makes Early Exit

PARIS -- Eleventh seed Nadia Petrova suffered a first-round defeat at the French Open for the second successive year when she was dumped out 7-5, 5-7, 6-0 by Czech Kveta Peschke on Tuesday.

The Russian, who was forced to withdraw during the Italian Open earlier this month because of a back injury, put up little resistance in the third set and Peschke, playing her first Tour-level match of the year, cruised to victory.

The first two sets contained 10 breaks of serve but Petrova looked on course when she leveled the match.

But with her movement nowhere near as good as it usually is, Petrova could not match Peschke in the decider and the world No. 182, who qualified for the event, raced through.

Petrova fears the back injury may force her to miss Wimbledon for the second successive year.

"I am trying to stay positive in my head, but I really don't know if i will be ok," she said. "I just really hope that in the end it's not that serious. I don't want to miss the grasscourt season again."

There was better news for Russia on Court 1, where Yelena Dementyeva had little difficulty in dispatching Germany's Angelique Kerber 6-3, 6-2.

Maria Kirilenko is also through, beating Maria Elena Camerin of Italy 6-3, 6-0.

In the men's draw, No. 13 Mikhail Youzhny advanced after barely hitting a ball when Jan Hernych of the Czech Republic pulled out after only nine points in the first game of the match because of a back injury.

"I really wanted to play today, actually. But I have a little pain in my back, so one more day rest is good," said Youzhny, who has reached three finals this year. "After Hamburg, I only practiced, so I think one more day for my back is good."

Roger Federer passed his first test, beating Michael Russell of the United States 6-4, 6-2, 6-4 in a match that started a day earlier.

Federer, who is bidding for a fourth straight major title and a career Grand Slam, led 6-4, 4-1 before rain halted play Monday. The top-ranked Swiss star returned to center court with sun breaking through the clouds Tuesday and quickly earned his spot in the second round.

"Winning in three sets, it's the perfect beginning," Federer said. "Over two days, it's always difficult, with the wind and the changing conditions compared to yesterday. And I didn't know this opponent. I'm really happy."

Federer didn't face a break point, winning 78 percent of points on his serve.

No. 19 Guillermo Canas, who beat Federer twice this year, reached the second round by defeating Victor Hanescu of Romania 6-3, 6-1, 6-4.

No. 7 Ivan Ljubicic of Croatia beat Arnaud Clement 6-1, 7-5, 7-6 (2) and No. 9 Tommy Robredo defeated Sergio Roitman 6-3, 6-4, 6-2.
