(AP) 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. ... It is one of my favorite tournaments on the circuit. Unfortunately, the injury has not completely healed and I will be unable to participate."
Bartoli's withdrawal opened a spot for former Stanford All-American 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.
