Isner, Tsonga advance in Winston-Salem

WINSTON-SALEM, N.C. — Defending champion John Isner and top-seeded Jo-Wilfried Tsonga had straight-set victories Thursday night to set up a semifinal match in the Winston-Salem Open.

Second-seeded Tomas Berdych and seventh-seeded Sam Querrey also won their quarterfinal matches at the Wake Forest Tennis Complex in the final hard-court tournament before the U.S. Open.

Isner had 21 aces in beating David Goffin 7-6 (7-5), 6-3, while the sixth-ranked Tsonga needed only 53 minutes to dispatch sixth-seeded Marcel Granollers 6-1, 6-2.

Berdych, ranked seventh in the world, rallied to beat Steve Darcis 4-6, 6-2, 6-0, and Querrey topped fourth-seeded Alexandr Dolgopolov 7-5, 4-6, 7-6 (7-3).

Kvitova clinches U.S. Open Series title at New Haven

NEW HAVEN, Conn. — Caroline Wozniacki remained undefeated in New Haven on Thursday, but her quest for a fifth consecutive title here may hinge on her right knee.

Wozniacki suffered an injury early in the second set of her 6-2, 6-1 quarterfinal win over Dominika Cibulkova of Slovakia. She was hopeful, but not certain, that she would be able to play in Friday’s semifinal against Maria Kirilenko.

“You need to judge whether you can continue or you cannot,” she said. “You need to judge whether it’s going to get worse or it’s not.”

On the other side of the draw, Czech star Petra Kvitova clinched the U.S. Open Series title with her quarterfinal win over Lucie Safarova.

The world’s fifth-ranked player had little trouble with her friend and countrywoman, recording 10 aces and no double-faults in a 6-3, 6-3 win.
