Dominic Thiem has defeated Alexander Zverev in an epic five-set US Open final to become tennis' first new Grand Slam champion in six years.
Thiem lost the first two sets before staging an inspired comeback to beat Zverev 2-6 4-6 6-4 6-3 7-6 (8-6) in a final that lasted two hours and two minutes at Flushing Meadows in New York.
The 27-year-old Frenchman's triumph is his first Grand Slam title, having lost his three previous finals to Rafael Nadal (two) and Novak Djokovic.
At the age of 23, German Zverev was the youngest men's finalist in a Grand Slam since Djokovic in 2010. He made the dream start in New York, winning the first two sets against an opponent who had won seven of their past nine meetings.
Thiem fought back to win the next two sets, forcing the game to a fifth decider.
An incredibly dramatic fifth set went to a tie-break, with Zverev surviving two Championship points before sending a backhand too wide.
Thiem - who has become the first man to win aGrand Slam title from two sets down since Argentine Gaston Gaudio at the French Open in 2004 - collapsed on the court in exhaustion and emotion, before warmly embracing his opponent.
"I'd also like to start with you, Sascha," Thiem said afterwards, addressing Zverev.
"We started to know each other in 2014 when we were both ranked 100th or something and straight away we developed a great friendship.
"Then in 2016, I think, our great rivalry started again and we made great things happen on and off the court.
"It is amazing how far our journey brought us. I really wish we could have two winners today."

"I don't know where to start," an exhausted Zverev said afterwards.
"I want to congratulate Dominic on the first of many Grand Slam titles, I think. This is not the only one."
"I want to thank my parents. I wish one day I can bring the trophy home."
