OSAKA: Australian third seed Samantha Stosur on Saturday dashed Caroline Wozniacki's title defence to reach the final at the Japan Open women's tennis tournament.

The 25-year-old Stosur, who also eliminated 2002 champion Jill Craybas of the United States on Friday, fired 12 aces to score a 6-0, 4-6, 6-4 victory over the Danish top seed.

Stosur, ranked 15th against Wozniacki's sixth, has yet to win a WTA title, but has won four ITF titles, three of them in Japan, including one here in Osaka.

In the final on Sunday, Stosur will play fourth seed Francesca Schiavone of Italy, who defeated Indian star Sania Mirza 6-2, 6-1 in the other semi-finals earlier in the day.
