France’s Mauresmo upset at French Open

Sharapova won the first five games against Chakvetadze, although the first two lasted a total of 24 points. Sharapova broke serve for the third time in the opening game of the second set, then held the rest of the way to win in 74 minutes.

Sharapova was briefly forced to delay her victory celebration. When Chakvetadze pulled a backhand barely wide on match point, Sharapova waited at the baseline while the chair umpire checked the mark and confirmed the call.

The two Russians shook hands, and Sharapova then grinned and blew kisses to the crowd on Court Suzanne Lenglen.

“I got off to a really good start, and I was in control from the first game,” Sharapova said. “As the rounds go on, it’s going to be a lot tougher than it is right now, so I have to raise my level another notch.”

Sharapova’s opponent Sunday will be unseeded Nuria Llagostera Vives, who upset No. 13 Nathalie Dechy of France, 7-6 (1), 6-3.

Petrova swept Shahar Peer 6-3, 6-1, and Bovina beat 17-year-old Frenchwoman Tatiana Golovin 6-3, 7-5. Golovin had seven double-faults and failed to convert two sets points in the second set.

Chakvetadze also had seven double-faults while Sharapova displayed the dominating serve and pinpoint groundstrokes that helped her win Wimbledon last year. She had 19 winners and 19 unforced errors.
