DUBAI, Feb 24: Defending champion Caroline Wozniacki reached the semi-finals of the Dubai Open here on Thursday, while US Open champion Sam Stosur was beaten by Jelena Jankovic of Serbia.
Caroline Wozniacki ousted Ana Ivanovic of Serbia 6-3, 7-5 in a meeting of former No. 1s, after Jankovic had beaten Stosur 6-4, 6-2 on Thursday.
The 22-year-old Wozniacki eased through the first set and then overcame tougher resistance in the second before overcoming the Serb 1 hour, 33 minutes.
Wozniacki is the highest-seeded player left in Dubai at No. 3 after top-ranked Victoria Azarenka pulled out of the tournament Wednesday because of an ankle injury.
Azarenka unseated Wozniacki from the No. 1 ranking last month by winning the Australian Open.
Wozniacki will play Julia Goerges after the unseeded German defeated Daniela Hantuchova of Slovakia 4-6, 6-3, 6-4.
Earlier, the eighth-seeded Jankovic was in control throughout the match as the fourth-seeded Stosur struggled with her game.
The Australian seemed to rush her shots for much of the first set, hitting the ball early and returning it long and wide. Stosur broke Jankovic early in the second, but the Serb broke right back and then pulled ahead 5-2 before wrapping up the match in 1 hour, 30 minutes.
Jankovic will meet fifth-seeded Agnieszka Radwanska in the semi-finals.
