Naomi Osaka splits with coach Patrick Mouratoglou after less than a year

The four-time Grand Slam champion is coming off a third-round loss at Wimbledon, as well as a second-round defeat to Emma Raducanu at the recent Citi DC Open.

"Merci Patrick," Osaka wrote on Instagram.

"It was such a great experience learning from you. Wishing you nothing but the best. You are one of the coolest people I've ever met and I'm sure I'll see you around."

Mouratoglou also posted to Instagram, stating: "I will always root for you and wish you nothing but the best."

The pair began their player-coach collaboration after she fell to Karolina Muchova in her second match at the 2024 US Open, dismissing Wim Fissette - who currently coaches Iga Swiatek.

In the past, Mouratoglou has coached the likes of Holger Rune, Grigor Dimitrov, Marcos Baghdatis, and Anastasia Pavlyuchenkova.

Osaka is the current world No. 51 and possesses a relatively poor 21-11 win/loss record in 2025.

Despite the disappointment, the former world No 1 lifted her maiden clay-court title at the WTA 125 event in Saint Malo and reached the showpiece match in Auckland in January - losing to fifth seed Clara Tauson.

Osaka hasn't made it past the third round of any Grand Slam since winning the Australian Open in 2021.

Her most recent attempt resulted in a 3-6, 6-4, 6-4 loss to Pavlyuchenkova in the last 32.

"I'm just going to be a negative human being today. I'm so sorry. I have nothing positive to say about myself, which is something I'm working on, admitted the four-time Grand Slam champion admitted, after the loss as SW19.

"Yeah, I'm glad to be done with this, and I'm looking forward to the hard courts."

Most intriguingly, the former world No 1 stated that she was looking for a 'long-term commitment' at the beginning of their partnership.

"The fact that he was Serena's coach made me want to avoid him just because his persona is so big," commented Osaka, at the time.

"This isn't rude, because I found out it's not true, but I didn't know if he was a good coach or he coached Serena. Then I met him, talked to him, worked with him on the court. He absolutely is a really good coach.

"I think I'm at a stage in my life that I don't want to have regrets. I'd rather pull the trigger on something and I don't want to say 'fail', but I feel like I really need to learn as much as possible in this stage of my career.

"I try not to get into relationships with people for the short term. I try to think of it as a long-term commitment."

Osaka is next due to participate in the Canadian Open, a WTA 1000 event, and will face world No 122 Ariana Arseneault in her opening match.
