Tsitsipas quits with injury against Rune at ATP Finals

TURIN : Stefanos Tsitsipas retired after just three games of his Green Group clash against Holger Rune at the ATP Finals on Tuesday, handing the Danish debutant his first victory in the event.

Greek world number six Tsitsipas looked uncomfortable as he trailed 2-1 and after consulting with a doctor at the changeover he decided that he could not continue.

Tsitsipas, who lost in straight sets to Jannik Sinner in his opening match on Sunday, appeared to be troubled by a back problem and left the court to a few jeers from the large crowd inside the Pala Alpitour.

Rune, who lost to world number one Novak Djokovic in his first match on Sunday, will now face Sinner in his final round-robin match still with a chance of reaching the semi-finals.
