A close call, but Zheng's more than happy

Veteran Zheng Jie's opening match was much harder than she expected, but the Chinese world No 40 was happy to be pushed all the way by a teenage compatriot.

What appeared on paper to be a lopsided match against Zhang Yuxuan turned into a grueling three-set battle as Zheng overcame a second-set scare to beat the wild card, 6-1, 3-6, 6-4 in 128 minutes.

Zhang, 18, proved to be a legitimate threat to Zheng, who was broken six times while making 44 unforced errors (three more than Zhang).
