Bartoli withdraws from Stanford
Wimbledon champion Marion Bartoli will miss next week's WTA Bank of the West event with a hamstring strain, the second loss of a drawcard in days for the hardcourt start of the North American summer.
The French grand slam winner withdrew only days after world No 2 Maria Sharapova pulled out to let a hip injury more fully recover.
Bartoli, who crushed Sabine Lisicki for the Wimbledon title this month, said her hamstring injury had been bothering her for some time.
"During Wimbledon I developed a strain which has not healed over the past two weeks," said the seventh-ranked French woman. "I've been receiving therapy and was optimistic that I would be able to participate in one of my favourite tournaments on the circuit.
"Unfortunately, the injury has not completely healed and I will be unable to play."
With the two biggest names missing, 2012 Wimbledon finalist Agnieszka Radwanska, 2011 US Open champion Samantha Stosur and 2010 French Open winner Francesca Schiavone will now highlight the field.
Bartoli won the title in 2009 over Venus Williams and lost the 2011 final to Serena Williams.
