Naomi Osaka and Mouratoglou Call Time on Partnership

Naomi Osaka and Patrick Mouratoglou have ended their coaching relationship just as she heads into the WTA Montreal, Canadian Open. The split comes roughly ten months after Osaka hired the French coach following her departure from long-time mentor Wim Fissette.

Together in 2025, Mouratoglou encouraged Osaka to step down to the WTA 125 level in Saint-Malo, where she captured her first clay-court title since returning to the tour. That spark helped her string together an eight‑match winning streak, though results subsequently cooled to a 3–5 stretch.

Their working dynamic was candid from the start. Osaka admitted initially feeling hesitant—his persona loomed large due to his work with Serena Williams—but warmed up once she got to know him on the court. Mouratoglou, for his part, emphasized that any collaboration rested on genuine admiration: “I would never work with a player if I don’t admire her,” he once said of Osaka.

The partnership also included turbulent moments—most notably Osaka’s tearful first‑round loss at the French Open, where she uttered a now‑iconic line about Mouratoglou going “from working with, like, the greatest player ever to, like … what the f**k is this?”. Despite that emotional fallout, Mouratoglou stood by her publicly, extending support after her Wimbledon exit earlier in the summer.

As Osaka recalibrates her camp ahead of the hard-court season, the split marks both an end and a fresh beginning—one defined by lessons learned, pressure managed, and expectations reset.
