Karolina Pliskova on Monday thrashed two-time Grand Slam champion Garbine Muguruza 6-3 6-1 to reach the Australian Open quarter-finals for the third time in a row.
The Czech Republic's seventh seed broke former Wimbledon champion Muguruza five times in the one-sided clash in the afternoon sunshine at Margaret Court Arena.
Pliskova needed just 24 minutes to win the second set. She will next meet Serena Williams for a place in the semi-finals.
