TOKYO (AP) Second-seeded Caroline Wozniacki of Denmark reached the Pan Pacific Open semifinals by beating eighth-seeded Carla Suarez Navarro of Spain 6-3, 6-3 Friday.
Wozniacki was in control from the start, breaking her opponent three times in the opening set at Ariake Coliseum.
"It was a little like playing chess," said Wozniacki, who won the tournament in 2010. "We opened up the court and tried to outplay each other."
The U.S. Open finalist will face Garbine Muguruza of Spain on Saturday.
"She's been playing well all week." Wozniacki said of Muguruza. "I need to make her run, take the ball early, need to serve and return well."
Muguruza, despite 10 double-faults, defeated Casey Dellacqua of Australia 3-6, 7-6 (5), 6-3.
Top-seeded Angelique Kerber of Germany also advanced, beating sixth-seeded Dominika Cibulkova 6-3, 6-0.
