30 Pics of Maria Sharapova "Upskirt Moment" in the 2012 London Olympics

Everything went Williams' way this day. She even dominated the wind, Sharapova said. "She's playing incredibly confident tennis," said Sharapova, who has lost to Williams the last eight times they've met, dating to that 2004 Wimbledon match.

"After winning Wimbledon (last month), you've seen her level progress so much here over this tournament. With every match she's played, she's getting better, hitting harder. So much power on the ball even against the wind today. Her shots were very powerful. She's done an incredible job of keeping that up." (See more Pictures)
