Japanese tennis star Naomi Osaka does not have anyone whom she can call a friend on the Women's Tennis Association (WTA) Tour.

During a live session with Rich Kleiman, manager of US basketball star Kevin Durant, Osaka was asked if there's any camaraderie between players on Tour, outside of their own circles or teams. Osaka replied: "I can speak for me, I don't really have that many friends on Tour. Not on purpose, but I just feel like I'm so busy that I'm sort of like in and out of the locker room."
