Slovakia's Dominika Cibulkova has rallied from a set down to defeat former US Open champion Sloane Stephens 4-6 6-2 6-3 and reach the quarter-finals of the China Open.
An error-prone Cibulkova allowed American Stephens to race into a one set lead before clawing her way back. Having dragged the match into a decider, Cibulkova found her range to close out victory in under two hours.
Cibulkova's first win over Stephens in three years, following defeats in Acapulco and at last year's US Open, earned her a last eight clash with Anastasija Sevastova.
The Latvian advanced with a comfortable 6-3 6-2 victory over Croatia's Donna Vekic.
Former world No.1 Karolina Pliskova cruised past Aliaksandra Sasnovich of Belarus 6-3 6-4 in a second round clash to set up a meeting with China's Wang Qiang.
