Montreal, QC, Canada, 10 August 2018 | AAP / Tennis Australia

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.

In their only only previous meeting, Cornet had beaten Barty in straight sets in the opening round of the 2014 French Open.

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 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.”
