Two-time Australian Open champion Naomi Osaka has stopped playing because of an injury after dropping the opening set of her third-round match against Belinda Bencic.

Naomi Osaka explained why she retired from her match at the Australian Open and how her abdominal injury keeps recurring.

Since returning to action a year ago, Osaka has shown signs of getting her game back together, including a memorable and narrow loss to then-No. 1 Iga Swiatek at the French Open.
