No. 2 seed Bartoli advances at Bank of the West

STANFORD, California (AP) Marion Bartoli escaped from some trouble in the first set and won 11 straight games to beat Mallory Burdette 7-5, 6-0, in the second round of the Bank of the West Classic on Thursday.

"Mallory played extremely well," Bartoli said. "She was taking the ball early and hitting winners into the corners. I felt like I was playing myself. She was just too good."

Bartoli's father came out of the stands to remind his daughter to use her feet more. That's when things changed.

"I had to wait for her to come down a little bit and I had to play better," Bartoli said. "I was very focused on my game, trying to get tactical and looking for my rhythm. I know how to play with pressure."

Burdette led 5-2 and was serving for set point when the second-seeded and 10th-ranked Bartoli suddenly became engaged in the match and fired off a series of winners.

Bartoli will next meet fifth-seeded Yanina Wickmayer in Friday's quarterfinal. Five of the top six seeds are still alive in the tournament.

Third-seeded Dominika Cibulkova of Slovakia advanced in the late match, beating qualifier Erika Sema of Japan, 6-1, 6-3.

Cibulkova's quarterfinal opponent will be ninth-seeded Romanian Sorana Cirstea, who was a 6-3, 6-3 winner over China's Zheng Saisai.

Urszula Radwanska of Poland upset eighth-seeded Marina Erakovic of New Zealand, 6-3, 3-6, 6-4, setting up a clash against the only other non-seeded player remaining in the draw, American Coco Vandeweghe.
