STANFORD, Calif. (AP) Two-time Wimbledon champion Petra Kvitova eased into the quarterfinals with a 6-2, 6-2 victory over Kateryna Bondarenko in her Bank of the West Classic debut on Thursday.

Kvitova, a No. 2 seed, will take on eighth-seeded American CiCi Bellis, a 7-6 (3), 6-2 winner over Veronica Cepede Royg.

''I served very well, and I was just trying to play my game - which I always try, and sometimes that works, sometimes not,'' Kvitova said after her 60-minute match. ''Kateryna is a dangerous player; she can catch lots of balls and I knew that I had to be focused and just play aggressive.''

Fourth-seeded Anastasia Pavlyuchenkova and No. 6 Coco Vandeweghe also advanced. Pavlyuchenkova closed her match with two aces for a 6-4, 6-0 win over Alison Riske. Vandeweghe dropped only three points on three service games in the first set and cruised past fellow American Nicole Gibbs 6-0, 6-2.
