The fourth number in the world ranking Stefanos Tsitsipas underwent surgery on his right elbow.
– Sometimes life is all your dreams and hopes. There are also days when life is about just putting one foot in front of the other, and that's okay too. Focused on a healthier and happier future.

Tsitsipas was forced to withdraw from the ATP Final Tournament during the competition.
