Olympic champion Zheng Qinwen's comeback tournament at the China Open ended abruptly on Monday when she retired from her third-round match against Linda Noskova.
Zheng had previously admitted that she was playing at "80%, 70%" of her powers in Beijing after beating Emiliana Arango in the second round in her first tournament since undergoing right elbow surgery in July. The load reached critical mass two days later in a hard-hitting clash against Czech No. 26 seed Linda Noskova, where Zheng retired in the third set with Noskova ahead 6-4, 4-6, 3-0.

Zheng later told reporters after the match that the rigors of WTA 1000-level competition may have been too much too soon.
"I start to feel a bit more, which is normal," she said. "I already expect that. So I decided when the pain's going higher, [so I] don't damage the area, I should stop.
"I've been keep thinking on in the second set, so I keep pushing, pushing, until I say, like, OK, that's it."
