Australian Open: Ashleigh Barty wins quarter-final rematch against Petra Kvitova

Ashleigh Barty will play 14th-seeded American Sofia Kenin in the Australian Open semi-finals after the world number one defeated Petra Kvitova in straight sets on Tuesday.

The top seed and last remaining Australian in the tournament survived a tough opening set to beat the Czech seventh seed 7-6 (8/6), 6-2 and reach the semi-finals for the first time.

This was revenge for the 23-year-old Barty after two-time Wimbledon champion Kvitova beat her at the same stage last year in Melbourne.
