Daniil Medvedev came from behind to beat US Open champion Dominic Thiem in a gripping encounter and win the biggest title of his career at the ATP Finals in London on Sunday.

The Russian fourth seed was second best for large periods at the empty O2 Arena but found a way back into the contest and prevailed 4-6, 7-6 (7/2), 6-4.

Medvedev, who beat five-time champion Novak Djokovic and world number two Rafael Nadal earlier in the week, is the first man to beat all three of the world’s top-ranked players at the season finale.

The giant Russian, 24, has now won 10 consecutive matches following his title earlier this month at the Paris Masters and his victory will taste sweet a year after a winless debut in London.

But it is a painful defeat for Thiem, who also lost in the final of the elite eight-man event last year, to Stefanos Tsitsipas.
