Local favorite Zheng Jie outclassed world number four Ana Ivanovic 7-6 (7-4), 2-6, 6-4 on Friday to reach the semifinals of the China Open.

Wimbledon Open semifinalist Zheng is the only Chinese woman still playing in the tournament after four others bowed out in the first round.

"This is a good win for me," said Zheng. "It was in China and in front of my home crowd. There were lots of fans supporting me, which gave me even more motivation."

Ivanovic, the French Open champion and second seed here, led inthe first set, but failed twice to serve it out before Zheng won in the tiebreaker.

The Serb fought her way back into the match, taking the second set despite an error-strewn display.
