Defending champion Naomi Osaka put an angry outburst behind her to move into the last 32 at the Australian Tennis Open with a straight-sets win over Saisai Zheng of China.

The Japanese third seed won 6-2 6-4 and now faces a potential third-round meeting with US teenager Coco Gauff, who plays Sorana Cirstea later.

22-year-old Osaka threw her racquet on the floor and kicked it after Zheng broke her serve in the second set.

After the match, Osaka said that she just wanted to win.
