It's tough, getting past Flavia Pennetta these days. Jelena Jankovic found out just how tough it is today in Zurich, when Pennetta continued her strong comeback statement with a 6-7, 6-3, 6-3 win over the number 1 seed. Jankovic could doubtless do with a rest, so it isn't the worst thing that could happen to her. She had to have her knee treated during the second set, but injury breaks occur very often with Jankovic.
Jankovic wasn't the only seed to go. 5th seed Agnieszka Radwanska was defeated by Katarina Srebotnik, 2-6, 7-6, 6-3.
Vera Zvonareva felt dizzy and had to retire in her second set against Anabel Medina Garrigues, Petra Kvitova defeated Sofie Arvidsson, 6-2, 6-1, and number 2 seed Anna Ivanovic defeated Marion Bartoli, 6-2, 6-4.
Then there was Monica Niculescu, who failed to take one game off of Victoria Azarenka.
In doubles, Schnyder and Groenefeld continued their success by defeating Peng and Zheng, 7-6, 6-3.
