“When I think about having fun, it’s like I don’t feel restrained,” she said. “Lately I felt really restrained. I’m not really sure why.

“I’m beginning to feel like I can’t hit the shots that I know I can, especially on my forehand… I just don’t have the same feeling.”

Osaka missed a large part of the 2021 season in order to protect her mental health, sparking a vital conversation about the pressure on athletes.
