NEW YORK, Sept. 3 (Xinhua) -- Chinese hopeful Zheng Qinwen was defeated by the 108th-ranked Jule Niemeier of Germany 6-4, 7-6(5) in the women's singles third round at the U.S. Open here on Saturday.

The first set went with service until the seventh game where Niemeier forced a backhand error from world No. 39 Zheng for a deciding break.
