Last week, Chang Kai-Chen knocked world number 1 and defending champion Dinara Safina out of the Toray Pan Pacific Open, defeating her 7-6, 4-6, 7-45. Now, in the second round of the China Open, it's wild card Zhang Shuai who has dismissed Safina, 7-5, 7-6.
That wasn't the only upset. Anastasia Pavlyuchenkova defeated 3rd seed Venus Williams 3-6, 6-1, 6-4.
Meanwhile, in a first-round match featuring two up-and-coming players, Alisa Kleybanova defeated wild card Yanina Wickmayer 5-7, 6-3, 6-3.
Sabine Lisicki had to retire in her first round match against Francesca Schiavone. There is an intestinal illness that is making its way through the tour, and now Lisicki has it. It's unfortunate that she had to retire again, but at least it wasn't an injury this time.
