Stefanos Tsitsipas withdrew from his second match at the ATP Finals against Holger Rune after only three games due to injury. There were concerns about his physical condition leading up to the tournament in Turin, but he seemed fine during his first match against Jannik Sinner. However, in his second match against Rune, Tsitsipas appeared to be in pain and was unable to continue after the third game, sitting down on his bench while trailing 2-1. The match ended after just 14 minutes.
