Wimbledon champ Marion Bartoli withdraws

STANFORD, California — Wimbledon champion Marion Bartoli withdrew from the Bank of the West Classic on Thursday because of a hamstring strain.

"During Wimbledon I developed a strain in my hamstring which has not healed over the past two weeks," said Bartoli, the 2009 tournament winner. "I have been receiving therapy and was optimistic that I would be able to participate. Unfortunately, the injury has not completely healed."

Bartoli's withdrawal opened a spot for Mallory Burdette in the main draw. Burdette turned pro shortly after the event last year and reached the third round of the U.S. Open.
