Naomi Osaka has a new opening at coach.
The former World No. 1 announced Sunday on social media that she and coach Patrick Mouratoglou are parting ways.
“Merci Patrick. It was such a great experience learning from you. Wishing you nothing but the best,” Osaka wrote. “You are one of the coolest people I’ve ever met and I’m sure I’ll see you around.”
Osaka, a four-time Grand Slam champion, has been in a career rut for years. Mouratoglou joined her staff in September of 2024 and there hasn’t been much improvement.
Osaka has not made it past the third round of a Grand Slam tournament since 2021 when she won the Australian Open. Now she will look for a new coach to help bring her back to form.
Mouratoglou has coached a variety of talented players, most notably Serena Williams, but he has not had much success as of late. He recently split twice with ATP player Holger Rune and now with Osaka. His opportunities could be dwindling.

Osaka will now prepare for the hard court season with the U.S. Open beginning August 24th. She lost her second match at the D.C. Open recently and will look to improve before heading to New York.
It’s a tough split but if it results in improvement for Osaka nobody will blame her.
