Naomi Osaka Hires Iga Świątek’s Ex-Coach Tomasz Wiktorowski Ahead of Canadian Open

Naomi Osaka has moved quickly to reshape her coaching setup after parting ways with Patrick Mouratoglou. The four-time Grand Slam champion announced their split on Instagram following a second-round loss to Emma Raducanu at the WTA 500 in Washington, and she's already tapped award-winning coach Tomasz Wiktorowski.

• Wiktorowski, who guided Iga Świątek to world No. 1 and four Major titles, will join Osaka's team in Montreal this week on a trial basis.


• Osaka opens her Canadian Open campaign against qualifier Ariana Arseneault, potentially with Wiktorowski courtside.

Stefanos Tsitsipas has officially brought back his father, Apostolos, as his coach after parting ways with Goran Ivanisevic. The world No. 30's brief stint with the former world No. 3 ended after just two events, during which Ivanisevic publicly criticized Tsitsipas's tennis.

Speaking ahead of his first-round match in Toronto, Tsitsipas admitted last year's breakup with his father was "very difficult" and "obnoxious," but said weeks of honest dialogue have paved the way for a healthier partnership. He insists on firm boundaries, mutual respect and transparent communication as they test their renewed collaboration at the Canadian Open.

Emma Raducanu opened her maiden Canadian Open in Montreal with a commanding 6-2, 6-4 victory over close friend Elena-Gabriela Ruse, rising to a three-year high of No. 33 in the world rankings. Battling rapid back-to-back tournaments—from a Washington semifinal only three days earlier—Raducanu showed no signs of fatigue on court.

During her on-court interview, the 2021 U.S. Open champion inadvertently praised her Washington "week in Chicago," before bursting into laughter and correcting herself to "DC." Despite four double faults, Raducanu dominated on the return and will face No. 32 seed Peyton Stearns next, while British coach Mark Petchey made a return to her box.

MONTREAL — Naomi Osaka's build-up to her second-round match at the Canadian Open was unexpectedly interrupted when a hotel fire alarm blared in the early hours, forcing the four-time Grand Slam champion to evacuate with only her passport in hand.

Despite the late-night disruption, Osaka began her tournament with a commanding 6-4, 6-2 victory over local hopeful Ariana Arseneault and now faces 13th seed Liudmila Samsonova as she seeks to rediscover her best form under new coach Tomasz Wiktorowski.
