3rd seed Agnieszka Radwanska made only six unforced errors today in her second round match against Venus Williams. Radwanska defeated Williams 6-2, 6-3, and was successful with all five break opportunities.
Top seed Victoria Azarenka had a much better time of it in the second round, losing only two games to Dinah Pfizenmaier; 2010 finalist Sam Stosur advanced, as did 2009 champion Svetlana Kuznetsova, Dominika Cibulkova, and Nadia Petrova. Cibulkova will play Sara Errani in the third round, and that has the potential to be a match worth watching.
Lucie Safarova is out--defeated by an in-form Maria Jose Martinez Sanchez. But the upset of the day was pulled off by Petra Martic, who defeated 8th seed (and 2011 semifinalist) Marion Bartoli 6-2, 3-6, 6-3. Sometimes Bartoli's serve deserts her, and today was one of those times.
Petra Cetkovska, who was lurking in the same quarter as Radwanska, was beaten today by Mathilde Johansson. Cetkovska has a 4-0 record against Radwanska, so one of the Polish star's obstacles has been removed.
Mixed doubles competition began today, and 4th seeds Lisa Raymond and Rohan Bopanna were defeated by Natalie Grandin and Paul Hanley.
