Naomi Osaka saved two match points as she battled back from the brink to reach the quarterfinals of the Australian Open with a 4-6, 6-4, 7-5 victory over in-form Garbine Muguruza on Sunday.

The Japanese third seed was chasing the match from the start on Rod Laver Arena and looked defeat square in the face in the third set when the Spanish 14th seed had two opportunities to win the match with a break of serve.

Osaka saved both match points — the first with an ace — to turn the tide in the contest decisively and Muguruza exited the tournament a couple of games later after failing to win a point in her final service.
