With the US Open just around the corner, Naomi Osaka’s preparations have been under close watch in tennis world. After making a strong run in Montreal, questions are swirling about who will be in her coaching box in New York. Recent reports suggest Osaka’s team has been actively evaluating her coaching options, setting the stage for an intriguing build-up to the final Grand Slam of the year.
Recent Developments Amid Coaching Trial In Montreal
Polish journalist Daniel Senkowski tweeted that Naomi Osaka will carry on her cooperation with Tomasz Wiktorowski. Senkowski wrote:
“Naomi Osaka will continue cooperation with Tomasz Wiktorowski,” citing Osaka’s agent, Stuart Duguid as the source. Though nothing has been announced officially, this seems correct given the recent coaching trial in Canada.
He added: “Osaka recently reached the final in Montreal with Wiktorowski, it was a trial period for them. Their next tournament together is US Open.”

Wiktorowski, who once coached Iga Świątek, was spotted in the stands throughout Osaka’s matches at the Canadian Open. His presence drew attention as Osaka advanced to the final in Montreal under his guidance. That week served as a coaching trial for their partnership, with Osaka ending as a runner-up, a strong indicator that the pairing might yield positive results moving forward.
Following her loss, Osaka forgot to congratulate the Canadian teenager Victoria Mboko in her on-court speech. This drew backlash from players and fans alike as she refused to attend the post-match press conference.

Naomi Osaka’s Coaching Situation and Recent Changes
Just days before the Canadian Open, Osaka confirmed her split from Patrick Mouratoglou via an Instagram story. Their partnership began in September 2024 but ended abruptly after Osaka’s second-round loss to Emma Raducanu at the Citi DC Open.
With Mouratoglou’s departure, Osaka called Wiktorowski for a trial in Montreal. He previously coached Agnieszka Radwańska from 2011 to 2018 and Świątek until October 2024, making him a seasoned choice for a player seeking renewed confidence.
Osaka’s reported decision to stick with Wiktorowski suggests she values continuity and the insights he offered in Montreal. Their trial run proved promising, and with the US Open just two weeks away, Osaka will aim to build on that momentum.
Meanwhile, Świątek moved swiftly after parting with Wiktorowski, hiring Wim Fissette, Osaka’s former coach from 2019, who helped Osaka claim her 2020 US Open and 2021 Australian Open title. Świątek’s appointment of Fissette underscores how leading players recycle proven coaching talent to maintain peak performance.
