Another retreat at the Nitto Atp Finals underway in Turin.

After Matteo Berrettini, Stefanos Tsitsipas is also forced to leave, the Italian Tennis Federation announced on Twitter.

The Greek was forced to forfeit by an arm problem that had stopped him yesterday after a quarter of an hour of training.

Tsitsipas had arrived in Turin not at his best, so much so that it was thought that Sinner would take over in his place. He also lost the first match in two sets against Russian Rublev. Now, Britain's Cameron Norrie takes his place in the green group.
