Wang stuns Stephens

China's Wang Qiang sent US Open champion Sloane Stephens crashing out of the Wuhan Open on a bad day for both this year's Flushing Meadows finalists in Hubei province.

American Stephens, the 14th seed, lost 6-2, 6-2 on Monday in her first WTA event since claiming her maiden Grand Slam title with victory over Madison Keys in New York earlier this month.

Hours before that shock first-round result, Stephens' compatriot Keys suffered a similar fate, losing 6-2, 7-6 (4) to Uzbekistan-born American Varvara Lepchenko.
