Mouratoglou was the longtime coach of Serena Williams but couldn’t stay longer with Osaka. The Japanese ace hired him after the second-round exit at last year’s US Open. During this run, she played three Grand Slam events and failed to deliver her best run. This year, she posted a 21-11 record and slipped to outside of top-50 in the WTA rankings.

Osaka’s only title glory this year came at the WTA 125 Open de Saint-Malo tournament which was her first title since 2021 Australian Open. She hasn’t crossed the third round of a Grand Slam event since winning the Australian Open 2021. There is no update on her new coach but Osaka will soon find a coach ahead of the US Open.
