Naomi Osaka Ends Coaching Partnership with Patrick Mouratoglou
Four-time Grand Slam champion Naomi Osaka has officially ended her coaching relationship with Patrick Mouratoglou, marking the close of a brief partnership that lasted less than a year. The Japanese tennis star announced on Monday via her social media platform X, expressing gratitude for the experience. “Merci Patrick… it was such a great experience learning from you,” Osaka posted.
Osaka began working with Mouratoglou, best known for his long-standing role as coach to 23-time Grand Slam winner Serena Williams, in September 2024. The decision to team up came as part of Osaka’s efforts to make a strong comeback to the tennis world following her break from the sport in 2023 due to the birth of her daughter.
However, Osaka has faced challenges regaining her form since returning to the professional circuit. Her performances have lacked consistency, and she has seen an overall dip in her rankings. Currently sitting at 49th in the world, Osaka’s recent Grand Slam appearances have been underwhelming. She exited in the first round of the 2025 French Open and was eliminated in the third round at Wimbledon.
Despite the setbacks, Osaka’s split with Mouratoglou signals a possible change in direction as she looks to rebuild her game and confidence. The brief partnership, while not yielding major wins, gave Osaka access to Mouratoglou’s extensive experience and elite-level training insights.
The parting was amicable, with no indication of disagreements or tension. It remains unclear who Osaka will work with next, but fans and analysts will be closely watching how this change influences her performance in upcoming tournaments.
Osaka’s journey continues to draw attention as she navigates the dual challenges of motherhood and elite competition. With her immense talent and determination, many still believe she can reclaim her place among the sport’s top players.
