The top half of the draw played their 4th round matches and 3 of the 4 top seeds moved into the quarterfinals, bar Petra Kvitova

(Rank/Seed)

1/1 Azarenka moved into her 1st US Open quarterfinal, beating Tatishvili 62 62 in a tougher match than the scoreline indicates

3/3 Sharapova may have been saved by a rain delay as Petrova turned the match around to lead 16 64 20, but Sharapova had a word with her Dad and came out firing to win 61 46 64 to reach her first US Open quarterfinal since 2006

11/11 Bartoli upset the US Open Series champion (5/5) Kvitova 16 62 60! Kvitova dominated early on just as she had done the other week in Montreal, but Bartoli won 11 of the last 12 games against an increasingly fatigued looking Kvitova to snap the Czechs 7 match winning streak and move into her first US Open quarterfinal

7/7 Stosur snapped the fairytale run of Robson 64 64. Robson hit too many unforced errors and was left to rue missed opportunities. Finally, after saving 8 match points, Robson lost on the 9th
