Before today, Agnieszka Radwanska had never beaten Francesca Schiavone. The Italian led their head-to-head 4-0 (all matches on hard courts). Radwanska, who said after the match that she wanted to win at least one match against the 5th seed, got her wish. Radwanska, seeded 9th, hit sixteen winners and made only eight unforced errors, defeating Schiavone 6-0, 6-2. Schiavone's forehand betrayed her, and she made one error after another.
Joining Radwanska in the quarterfinals is 16th seed Maria Sharapova, who defeated 4th seed Sam Stosur 6-4, 6-1.
Out of competition in doubles are 7th seeds Bethanie Mattek-Sand and Meghann Shaughnessy. They were defeated by wild card Sloane Stephens (who has an outstanding junior doubles record) and Yanina Wickmayer.
