WIMBLEDON, England (AP) — Maria Sharapova won her Olympic debut indoors Sunday, beating Shahar Peer of Israel 6-2, 6-0.

Playing under Wimbledon's retractable roof on Centre Court because of rain, No. 3 Sharapova served well, returned aggressively and swept the final eight games.

Sharapova completed a career Grand Slam last month when she won the French Open. She carried the Russian flag in the opening ceremony after missing the 2008 Olympics because of a shoulder injury.

Sharapova improved to 7-0 against Peer.

While the roof was closed from the start of the day, 22 matches on other courts were postponed because of rain, including one involving top-seeded Victoria Azarenka of Belarus.
