Maria Sharapova struggled in her 6-3, 7-6 (7-5) win over Austria's Sybille Bammer in double-faulting 17 times. "I'm actually having a competition with myself to see how many errors and double faults I can make and still win the match in two sets," said Sharapova.
"It's pretty interesting. The more I was out there, the worse I was playing." Sharapova set up a third-round match against Vera Zvonareva, the seventh seed.
