American Amanda Anisimova, ranked 60th in the world, saved two match points and smashed winners at will to beat reigning champion Naomi Osaka 4-6, 6-3, 7-6 (10-5) in the third round of the Australian Open on Friday.

Anisimova produced a superb display to knock out the Japanese and disappoint those who had been salivating at the prospect of a fourth-round showdown between the four-time major winner and Australian world No. 1 Ash Barty.

"I just want to soak in this moment," Anisimova told reporters. "I'm just extremely happy. It was an amazing match. It was very close.
