There were dramatic reversals of fortune in the Stanford quarterfinals today. In defending champion Marion Bartoli's match against Victoria Azarenka, Bartoli could do almost nothing wrong for a set and a half. Serving well and hitting the laser-like returns of serve for which she is known, the 4th seed dominated Azarenka for some time. With Bartoli, though, you never know whether one of two things is going to occur--she could become injured, or her serve could go to pieces. Today, it was the latter. Even so, Bartoli was up 3-1 in the final set, but she had so much difficulty with her serve that 8th-seeded Azarenka was able to overcome her and win the match 3-6, 6-3, 6-3. Azarenka is now 4-0 against Bartoli.
Azarenka's opponent in the semifinals will be top seed Sam Stosur, who faced a tough challenge from 7th seed Yanina Wickmayer. Both players served at a very high level during the first two sets. Stosur took the first one, 7-5, and Wickmayer won the second, 6-3. Wickmayer got off to an early lead in the third set. In fact, she led 2-0, 40-15, and then--in the course of four breaks of serve--Stosur edged ahead, taking the final set 6-3.
3rd seed Agnieszka Radwanska and Maria Kirilenko played a tight first set, which Radwanska won, 7-5. In the second set, though, Kirilenko served poorly and did not win one game.
