World number one Aryna Sabalenka progressed to the quarter-final of the China Open with a straight-set victory over Italy's Jasmine Paolini.
The Australian Open winner will face 2022 Wimbledon champion Elena Rybakina in the last eight.
Meanwhile, US Open champion Coco Gauff saved four set points to beat Veronika Kudermetova 7-6 (7-5) 6-2.
The victory marks Gauff's 15th consecutive win - the longest winning run of any player on the WTA Tour this year - surpassing Polish world number two Iga Swiatek's run of 14 victories which came earlier this year.
"I'm really happy with how I've been able to troubleshoot and problem-solve," Gauff said after the win.
