CARLSBAD (California), July 19: 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.

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.

Bartoli advanced despite losing serve eight times against the world 59th-ranked King.

The French player lost serve in the opening game of the final set but fought to get it back as she broke for four-all before closing out the match at La Costa on a concluding break.

US Olympian Varvara Lepchenko upset South African eighth seed Chanelle Scheepers 6-4, 6-2 to reach her third quarter-final of the season.

Lepchenko next takes on fourth seed Nadia Petrova, who beat American Alexa Glatch 6-4, 6-3.
