Two-time champion Zhang beaten in Guangzhou

Zhang Shuai's bid for a third Guangzhou Open crown was ended by Viktorija Golubic in Thursday's quarter-final.

The two-time champion, whose only WTA Tour singles titles have come at this event, came up short as Golubic ran out a 6-3 3-6 6-4 winner.

Sofia Kenin, another seed, staged a remarkable first-set turnaround to ensure she remained in the competition.

The American trailed 5-2 in the opener but rallied to defeat Jasmine Paolini 7-5 6-1.
