PARIS -- Maria Sharapova reached the semifinals at the French Open, the only Grand Slam tournament she hasn't won, by beating 23rd-seeded Kaia Kanepi of Estonia 6-2, 6-3 on Wednesday.

The second-seeded Sharapova lost in the Roland Garros semifinals in 2007 and last year. She won Wimbledon in 2004, the U.S. Open in 2006 and the Australian Open in 2008.

Against Kanepi, Sharapova played much better than she did in her previous match, when she had 12 double-faults and was broken nine times. Still, there were issues Wednesday, including when Sharapova was broken trying to serve it out.

The Russian is expected to move up to No. 1 in the rankings, overtaking Victoria Azarenka, if she can reach her first French Open final.

Kanepi dropped to 0-4 in major quarterfinals.
