Maria through to another semi

Maria Sharapova reached her 12th semifinal of the season by beating fifth-seeded Ana Ivanovic of Serbia 7-6 7-5 at the Generali Ladies championship in Linz on Friday.

The top-seeded Russian missed three set points while serving at 5-4 in the first and when she led 5-2 in the second set, double-faulted twice while serving for the match and was broken.

"I didn't know Ana's game too well as we had never met before, but she played some amazing tennis," Sharapova said.

"I shouldn't have let her come back in the second set. I hope to learn from that."

Sharapova will next play third-seeded Patty Schnyder or Vera Zvonareva.
