Wild-card Razzano stuns Kvitova at Carlsbad

CARLSBAD, Calif. (AP) — Wild-card entrant Virginie Razzano stunned third-seeded Petra Kvitova 6-7 (6), 7-5, 7-6 (8) on Friday in the Southern California Open quarterfinals.

Razzano, ranked No. 131 in the world, squandered four match points and had to stave off two match points from Kvitova in the third-set tiebreaker before Kvitova double-faulted to end the match at 3 hours, 35 minutes.

“I think I was nervous,” Razzano said. “I’m human. I’m not a robot. Sometimes you feel stress. I tried to focus on the points.”

The match was the second longest on the WTA Tour this year behind one between Bethanie Mattek-Sands and Anastasia Rodionova that lasted 3:42 at Charleston in April.

Razzano will face the winner of a match between second-seeded Agnieszka Radwanska of Poland and fifth-seeded Sam Stosur of Australia.

In the other quarterfinals, No. 7 seed Ana Ivanovic of Serbia beat fourth-seeded Roberta Vinci of Italy 6-1, 6-7 (1), 6-2, and top-seeded Victoria Azarenka of Belarus played Poland’s Urszula Radwanska.
