DOHA, Qatar(AP) Venus Williams has reached to her second straight Sony Ericsson Championships final by defeating Jelena Jankovic 5-7, 6-3, 6-4.

Williams broke the former top-ranked Serb three times in a row en route to a 5-3 lead in the decisive set. The defending champion then sealed the win with a forehand that bounced in off the net cord.

She could come up against her sister Serena, who played Danish teenager Caroline Wozniacki in the second semifinal.

It was the ninth three-setter in 10 meetings between Williams and Jankovic, with the head-to-head series tied at 5-5.

Williams advanced to the semifinals despite winning just one of her three round-robin matches.
