Barty downs Kvitova in China for last four spot
World No.1 Ashleigh Barty has advanced to the semi-finals at the China Open, beating Petra Kvitova 4-6 6-4 6-3.
It was another superb contest, leading the French Open champion to claim: "From my opinion, that was one of the highest quality matches I played all year.
"Petra always has a way of bringing out the best in me, she really does."
The Australian faces Kiki Bertens next after the Dutch star upset No.3 seed Elina Svitolina in straight sets. "I think I stepped up my game today," Bertens said.
