Jannik Sinner made history as the first Italian ever to reach the last four of the ATP Finals on Thursday after Novak Djokovic beat Hubert Hurkacz 7-6 (7/1), 4-6, 6-1.
World number four Sinner is guaranteed at least second spot in the Green Group thanks to Hurkacz, who played his only match of the season-ending tournament as a replacement for injured Stefanos Tsitsipas, claiming a set against Djokovic.
The Serbian world number one is now sweating on his semi-final place despite a second win from three matches, as his qualification hinges on the result of Sinner’s final match with Holger Rune later on Thursday.
