Isner, Tsonga to battle in semis

In Winston-Salem, N.C., defending champion John Isner and top-seeded Jo-Wilfried Tsonga had straight-sets victories 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, a former University of Georgia player, 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).

• In New Haven, Conn., Petra Kvitova clinched the U.S. Open Series title with a victory over Lucie Safarova in the quarterfinals of the New Haven Open.

The series win makes Kvitova eligible for a bonus of up to $1 million depending on her placement in next week’s U.S. Open.

In the semifinals today, she will play the winner of the late match between Marion Bartoli and Sara Errani.
