Austria's Dominic Thiem claimed his first Grand Slam title with a jaw - dropping comeback to edge past Germany's Alexander Zverev 2 - 6, 4 - 6, 6 - 4, 6 - 3, 7 - 6(6) in Sunday's US Open final here.
From being two sets down, the 27 - year - old world number three was in all sorts of trouble before hitting back from a break down to take the third.
In a nerve - wracking fourth set, Zverev faltered on serve at 3 - 4 allowing Thiem to take the contest to a decider.
Thiem then trailed 5 - 3 in the decider but rode on baseline winners to take it into a tiebreak.
