Wozniacki wins at China Open

Andy Roddick was eliminated in the first round of the China Open Monday, falling to South Africa's Kevin Anderson 6-4, 7-5, while Caroline Wozniacki rallied from a set down to beat Lucie Hradecka of the Czech Republic 3-6, 6-0, 7-5.

Roddick managed to handle Anderson's huge serve, but the sixth-seeded American struggled with his own and was broken in the seventh game to go one set down.

The second set brought more of the same, and while Roddick evened things up at 5-5, Anderson's momentum carried him through to the win.

"If I break twice and don't win a set that says my serve isn't on," Roddick said. "It's unacceptable."

The 29-year-old Roddick's world ranking has slipped to 15th after several early-round losses this year.
