Sixth-ranked Coco Gauff again made a slow start and had to rally to beat Ukrainian qualifier Yuliia Starodubtseva 2-6, 6-2, 6-2 to make the China Open semifinals on Thursday. Gauff will next play Paula Badosa of Spain, who earlier ended local wild card Zhang Shuai's unexpected run at the title. The No. 115-ranked Yuliia Starodubtseva had not lost a set in her three matches this week and quickly took the lead, making 10 winners and holding Gauff to zero in an error-strewn first set for the American.
