Win or lose, Jiang confident Williams will be shocked

Chinese tennis head coach Jiang Hongwei believes Zheng Jie will be able to shock Serena Williams in the Wimbledon semifinal, which takes place tonight on Center Court.

Zheng, 24, beat Czech 18th seed Nicole Vaidisova 6-2, 5-7, 6-1 on Tuesday to become the first Chinese player to reach the last four of a Grand Slam.

"As long as Zheng plays at her level, anything is possible," Jiang told Sina.com yesterday. "It's already a huge achievement, beating five formidable rivals as a No 133 wild-card player, including some elite players. So she has proven that she is not afraid of big names.
