Top seed Marion Bartoli survived a struggle lasting for more than three hours, with the Frenchwoman overcoming a massive 18 double-faults to advanced at the WTA hardcourt event here on Wednesday. Bartoli defeated American Vania King 6-4, 5-7, 6-4 in an error-plagued marathon match to reach the quarter-finals after a bye in the first round. “It’s a very hard surface,” Bartoli said. “Playing three hours is not really helping, but I think it was a great fight from both of us and we tried our best.” Bartoli, who will not play in the London Olympics due to a longstanding dispute with the French federation, won a battle in which both women took lengthy injury breaks, with Bartoli going off court for treatment in the third set.
