Hsieh Su-wei and Peng Shuai did something today that no one else at the Australian Open had done: They took a set off of the Williams sisters. The sisters took the first set, 6-2, and Hsieh and Peng took the second, 6-4. In the first five games of the third set, there were four breaks. At 3-all, the Williams sisters broke again, then held, then successfully served for the match at 5-3.
I have already written about the two big doubles thrillers that took place today. There was another quarterfinal, of course. Casey Dellacqua and Francesca Schiavone defeated Anna-Lena Groenefeld and Patty Schnyder, 0-6, 7-5, 6-1.
