US Open champion Sloane Stephens and runner-up Madison Keys were knocked out of the Wuhan Open in the first round on Monday.
In their first matches since the final at Flushing Meadows, the 17th-ranked Stephens lost to Wang Qiang of China 6-2, 6-2, while the 12th-ranked Keys was beaten by fellow American Varvara Lepchenko 6-2, 7-6 (4).
The last time Grand Slam finalists lost their next match was after 2005 Wimbledon, where Venus Williams beat Lindsay Davenport.
Also, defending champion Petra Kvitova lost for the first time in Wuhan on her third visit. Kvitova won in 2014 and last year, when she dropped just one set. It took Peng Shuai 3 1/2 hours to knock her out 7-6 (7) 6-7 (5) 7-6 (3).
