Wang Qiang, who was China's last hope at the US Open in the Singles events, has been bounced.
She went down to the Czech Republic's Barbora Zahlavova Strycova in a 3rd set tie-breaker.
In other action, it was Italy's Sara Errani advancing to the third round of the tournament, despite illness.
"Yeah, really tough match for me already this morning I woke up feeling bad so was not easy. I warm up, was a lot of headache and like fever and this thing. So just try to stay there. In the second set she start to make some mistakes the first game, and I just continue and try to stay there. I mean, feeling bad, but just try to fight."
Mona Barthel of Germany, Simona Halep from Romania and American Shelby Rogers have also made it through.
