New Delhi: Naomi Osaka has parted ways with coach Patrick Mouratoglou after working together for less than a year. She announced the decision just three days after her second-round loss at the D.C. Open and ahead of her appearance at the Canada Open. The two-time US Open champion will now set her sights on making a strong comeback at the year’s final major which begins in New York on August 24.
The four-time Grand Slam winner shared the news on her X (formerly Twitter) account, posting a photo where she is seen practicing a serve while Mouratoglou stands nearby. Her caption read: “Merci Patrick! It was such a great experience learning from you. Wishing you nothing but the best. You are one of the coolest people I have ever met and I am sure I will see you around.”

She also posted the same message and photo on her Instagram story. In response, Mouratoglou shared a carousel of images of them working together with a caption, “Nothing lasts forever. What counts is what a collaboration has brought to each other and what lasts after. After 10 months of collaboration, we have decided to part ways professionally. I am grateful for the trust, the journey, and what we have built together. I will always root for you and wish you nothing but the best @naomiosaka.”

The friendly exchange between the two grabbed attention online, though some fans questioned the timing. Regardless, it appears the decision to part ways was mutual and respectful.
Osaka’s coaching struggles
Mouratoglou, who is best known for coaching 23-time Grand Slam champion Serena Williams for several years, was hired by Osaka following her split with Wim Fissette. That partnership ended shortly after Osaka’s second-round exit at the 2024 US Open, ending a four-year stint.
Currently ranked 51st in the world, the former World No.1 has struggled for form, having not progressed beyond the third round in any Grand Slam since her 2021 Australian Open triumph.
