Ashleigh Barty is out of the Australian Open after falling victim to the awesome firepower of Japan’s Naomi Osaka.

Unseeded Osaka crunched clubbed 12 aces and 24 clean winners past Barty to send Australia’s last women’s singles hope packing with a crushing 6-4 6-2 third-round defeat on Saturday.

Osaka’s reward is a shot at world No.1 Simona Halep for a place in a grand slam quarter-final for the first time in her career.
