The U.S. Open culminated 14 days of great, exciting tennis this weekend with the Men’s Championship Final Sunday.

It was an international, global affair on the grand court of Arthur Ashe Stadium in Flushing Meadows, Queens, at the Billie Jean King Tennis Center.

Stan Wawrinka, 31, representing Switzerland, defeated Serbia’s Novak Djokovic 6-7, 6-4, 7-5, 6-3 for his first U.S. Open Men’s Singles title, his third Grand Slam trophy, in a grueling, three-hour and 55-minute match that could have extended even further into the night.

“This is amazing for sure. An amazing two weeks,” said Wawrinka. “I spend so much time on the court. Today, I knew it will be a really tough battle again playing the No. 1 player, Novak Djokovic, who always pushes you to play your best tennis if you want to beat him.”

Djokovic noted that Wawrinka was the more courageous player this day, and Wawrinka admitted that he had to push himself to his limits.

“Today, I was trying to stay with him. I was trying to be tough with myself,” Wawrinka said, admitting that this was his most painful, physically and mentally challenging Grand Slam. He was completely drained afterward. “I was suffering on the court, but I’m happy and proud of what I achieved today,” he said. “You have to accept to suffer, and you have to almost enjoy to suffer.”

Djokovic, 29, the Open’s Men’s Singles defending champion, also won it in 2011. Wawrinka has won the Australian Open (2014) and the French Open last year in 2015.

Djokovic defeated Gael Monfils of France Friday. Wawrinka defeated Kei Nishikori of Japan. Friday’s semifinals preceded Saturday’s Women’s Singles Final won by Angelique Kerber, 28, also this year’s Australian Open winner. Kerber, repping Germany, defeated Karolina Pliskova of Czechoslovakia. Pliskova, 24, holds the individual distinction of beating both Venus and Serena Williams during the week to advance to the final.

The championship winners each received $3.5 million and the traditional silver cup. The runner-ups took home $1,750,000.
