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. This was Osaka’s first run to the third round at a major tournament since 2022. She missed time in recent seasons because of mental-health breaks, then was off the tour while pregnant. Her daughter, Shai, was born in July 2023. Osaka began this season by making it to the final of a tournament at Auckland, New Zealand, on Jan. 5, but she stopped playing in the title match there because of an abdominal injury. On Friday, Osaka was visited by a trainer during a changeover late in the first set.
