NEW YORK — Austria's Dominic Thiem finally claimed his first Grand Slam title with a stunning comeback to beat Germany's Alexander Zverev 2-6 4-6 6-4 6-3 7-6(6) in a brutal and nerve-jangling U.S. Open final on Sunday, Sept. 13.
The 27-year-old world number three, beaten in his first three Grand Slam finals, started as favorite but appeared to have blown his golden chance as he fell two sets behind.
Thiem, who had dropped only one set en route to the final, looked stifled by nerves early on but gradually broke the shackles to hit back from a break down to take the third.
Zverev faltered on serve at 3-4 in a high-quality fourth set allowing Thiem to take the contest to a decider.
A limping Thiem trailed 5-3 in a tense decider but Zverev could not close it out and the Austrian summoned some incredible baseline winners to take it into a tiebreak.
A gut-wrenching climax saw Thiem squander two match points from 6-4 with forehand errors but he would not be denied and set up a third match point with a passing shot before Zverev fired wide after four hours and two minutes.
"I wish there were two winners today, we both deserved it," Thiem, the second Austrian to win a Grand Slam title after Thomas Muster's 1995 French Open title, said on court after a tearful speech from his crestfallen 23-year-old opponent.
Thiem had lost the last two French Open finals to Rafa Nadal and this year's Australian Open final to Novak Djokovic.
This time he started as the favorite but needed to become the first player to win a Grand Slam title from two sets down since Gaston Gaudio at the 2004 French Open to end his wait.
Thiem is the first male player born in the 1990s to claim a Grand Slam and the first besides the big three of Nadal, Djokovic and Roger Federer to claim one of the majors since Stan Wawrinka won the 2016 U.S. Open.
