Thiem, 26, who edged a tight first set, fell away in the second and the start of the third before fighting back. But Tsitsipas forced a tie-break, and then won it, at a raucous O2 Arena. In the tie-break Tsitsipas saw a 4-1 lead become 4-4 before he held his nerve to take the match with three straight points. The Greek is just the seventh man to win the season finale on his first appearance and the sixth-youngest winner in history.
