Osaka and her boyfriend Cordae, 25, announced in January that she was expecting her first child.

Osaka, who was ranked No. 1 in January 2019, has four Grand Slam titles — two Australian Opens (2019, 2021) and two U.S. Opens (2018, 2020) — among her seven career victories.

Osaka played in just 11 tournaments in 2022. She took much of 2021 off for mental health reasons.
