Australian No.1 Ashleigh Barty booked a place in the Coupe Rogers quarterfinals with a straight-sets victory over France’s Alize Cornet.

Barty hit six aces to overcome the world No.34 7-6(3) 6-4 in one hour and 47 minutes in Montreal on Thursday.

The Frenchwoman also stunned Wimbledon champion Angelique Kerber 6-4 6-1 in her previous match in Canada on Wednesday.

Cornet also tested Barty on Thursday, with the Australian having to break her four times and close out a first-set tiebreak.

The second set was much more straightforward for Barty, who will face Dutch world No.18 Kiki Bertens for a place in the semifinals.

Bertens upset Czech world No.8 Petra Kvitova 6-3 6-2.

“It’s going to be a difficult match, of course,” Bertens told wtatennis.com about facing Barty.

“She’s playing some great tennis. Smart girl, also with a lot of slice. I don’t know what the conditions are going to be tomorrow, but we’ll see then. We’ll make a good plan, and hopefully it’s going to be a great match.”
