Defending Australian Open champion Naomi Osaka will make her highly anticipated return to the court next month at a warm-up tournament for the season-opening Grand Slam in Melbourne, organizers said Friday.

The WTA lead-in event will start on Jan. 4 at Melbourne Park before the Australian Open kicks off at the same venue from Jan. 17.

Osaka, who also won the Australian Open in 2019, resumed training last month, ending a self-imposed break from tennis.
