Naomi Osaka has parted ways with coach Wim Fissette after four years together across two stints, the 26-year-old announced late on Friday.
It comes after she admitted to being frustrated with recent results following an early exit from the US Open last month.
The Japanese tennis star began working with the Belgian in 2020 and has had two stints with him.
Osaka, 26, won two of her four Grand Slams – the 2020 US Open and 2021 Australian Open titles – with Fissette in her corner.
“Four years, two Slams and a whole lot of memories. Thanks Wim for being a great coach and an even greater person. Wishing you all the best,” Osaka wrote on Instagram.
Fissette rejoined Osaka when she returned to tennis in January following the birth of her daughter in July 2023.
“It’s been a little difficult because obviously I can only gauge how I’m doing by results,” she said after exiting the US Open last month.
“I feel faster. I feel better, but I lost in the second round. So it’s a little rough.
“I feel like I’m working way harder than I’ve ever worked in my life, so it needs to turn into something.”
Of the 16 tournaments Osaka has played this season, she has made the quarter-finals in only two – Doha and ‘s-Hertogenbosch – and the Japanese player has also failed to go past the second round in each of the four Grand Slams.
