Having already taken out both Zheng Jie and Agnieszka Radwanska, Sybille Bammer extended her Cincinnati run today by upsetting 2nd seed Serena Williams. I saw very little of this match; Williams made a lot of unforced errors--47, to be exact--and Bammer held forth quite well. She had to serve for the match twice, but she prevailed at 7-5, 6-4. The word is that Williams was ill today, which certainly would have affected her level of play.
Also continuing her good run was Kim Clijsters, who defeated 6th seed Svetalana Kuznetsova, 6-4, 4-6, 6-2. Victoria Azarenka double-faulted 11 times (what is it with all the double faulting?) in her match against 5th seed Jelena Jankovic, who won the match 7-5, 7-6. Daniela Hantuchova defeated Vera Zvonareva, and Elena Dementieva defeated Sorana Cirstea.
Caroline Wozniacki won her third round match against Melinda Czink when Czink retired with a lower back injury. Czink upset Ana Ivanovic in the second round.
And finally, top seed Dinara Safina defeated Peng Shuai in straight sets to advance to the quarterfinals.
