Naomi Osaka didn’t waste time moving on from ex-coach Patrick Mouratoglou.
Former world No. 1 Osaka will begin working with Polish coach Tomasz Wiktorowski, Iga Swiatek’s ex-coach, on a trial basis starting in Montreal this week.
It’s a case of trading coaches as Swiatek currently works with Osaka’s ex-coach Wim Fissette.
The Polish website Polski Tennis reported the new partnership, confirmed by journalist Courtney Nguyen.
Under Coach Wiktorowski’s guidance, Swiatek captured four of her six Grand Slam titles. The pair parted in October of 2024 with Swiatek subsequently hiring Osaka’s ex-coach. Though Swiatek did not defend her Roland Garros championship, she made history as the first Polish player to win Wimbledon crushing Amanda Anisimova, 6-0, 6-0, in The Championships final earlier this month.
Swiatek commenced her run with Wiktorowski at the end of the 2024 season. The pair captured four of Swiatek’s Grand Slam titles during their three-year partnership, and logged 19 of Swiatek’s 22 career titles. She was previously coached by Piotr Sierzputowski, and the pair won Roland-Garros together in 2020.
“Coach Wiktorowski joined my team for three seasons, when I strongly needed changes and a fresh approach to my game,” Swiatek said after splitting wtih the Polish coach. “His experience, analytical and strategic attitude and enormous knowledge about tennis helped us to achieve things I’ve never dreamed of only a few months after we started working together.
“Our main goal was to become No.1 player in the world and coach Wiktorowski was the one who said it first. We aimed very high, we headed to every tournament with a clear goal to win it. Together with coach Wiktorowski we won many tournaments and 4 Grand Slams.”

Osaka announced her split from Patrick Mouratoglou, who coached her for nearly 11 months, over the weekend.
“Merci Patrick. It was such a great experience learning from you,” Osaka posted on Instagram. “Wishing you nothing but the best. You are one of the coolest people I’ve ever met and I’m sure I’ll see you around.”
