Stosur too good for Zheng in Los Angeles

A shaky Sam Stosur lost her first set to a focused Zheng Jie in their LA Women's Tennis Championships quarterfinal today. But when the second set began, Stosur was a different player, gradually finding her rhythm against Zheng, and eventually using her mighty serve to dominate, 4-6, 6-3, 6-4.

Stosur's next opponent is Sorana Cirstea, assuming Cirstea is able to play.
