July 30, 2025: In one of the most surprising tennis headlines of the past few days, Naomi Osaka and renowned French coach Patrick Mouratoglou have mutually agreed to part ways, ending their coaching collaboration after less than a year. Despite the high expectations surrounding this partnership, the on-court results did not materialize as anticipated, with the Japanese star securing only one WTA title during their time together.
Currently, the former world number one remains a significant distance from the top ranks of the WTA rankings and has struggled to reclaim the form needed to contend for major titles. Many experts and insiders believed that Mouratoglou, known for his success with other top players, was the ideal coach to guide Osaka back to the summit of women’s tennis. However, he seemingly failed to make the expected impact, and Osaka announced the separation just before the start of the Montreal WTA tournament.
Osaka’s sole title during her collaboration with Mouratoglou was the Saint-Malo WTA 125. This single victory is considered a minimal return for a champion of her caliber, who has previously been a dominant force and a benchmark in women’s tennis.
On a recent episode of Andy Roddick’s podcast, veteran tennis analyst Jon Wertheim admitted that the news of this split didn’t come as a major surprise to him. “I don’t think this was a huge surprise. This has been a relationship of less than a year,” Wertheim stated. He elaborated on the reasons behind his perspective: “Osaka has won a fair amount of matches but not at the biggest and best events. Patrick has got his hand in a million pots and is promoting a book and is doing the tennis showdown. Naomi is based in Miami and Patrick is an ocean away in Nice.”
Wertheim also questioned the core value of the partnership, particularly in light of Osaka’s current struggles with confidence. “Patrick is also a guy who pumps a player up with confidence, I think he is much better known for that than any tactical expertise and I think if a player doesn’t have confidence, as Naomi doesn’t appear to have much of right now, I am not sure what the relationship is all about,” he concluded.
The separation marks another chapter in Osaka’s ongoing journey to rediscover her peak form and competitive edge on the women’s tour.
