After Matteo Beretini, Stefanos Tsitsipas also left the ATP finals in Turin.
The Greek tennis player retired due to an elbow injury.
Tonight, Tsitsipas was supposed to play with Kasper Ruda in the 2nd round of the group stage, and Cameron Nori will play in his place until the end.
Nori starts from 0-1, because Tsitsipas lost to Andrej Rubljov at the start.
Beretini was replaced earlier by Janik Siner, who defeated Hubert Hurkač last night.
