Roger Federer served superbly once again as he beat Stan Wawrinka to set up a US Open final against Novak Djokovic.
Second seed Federer beat his fellow Swiss 6-4 6-3 6-1 to reach the final without losing a set, and having dropped serve just twice.
The 34-year-old goes on to face top seed Djokovic, who thrashed defending champion Marin Cilic 6-0 6-1 6-2.
It will be the first US Open final since 2009 for Federer.
Djokovic, 28, has the opportunity to claim his 10th major title and third of the year, the Serb having won the Australian Open and Wimbledon but lost in the French Open final.
“Novak has had a tremendous year,” said Federer, a 17-time Grand Slam champion. “There’s always a lot on the line when we play.
“He’s the best mover on the hard courts, he’s tough mentally, but I like that challenge and I’ll be ready for it.”
Djokovic needed 85 minutes to see off Cilic, who was comprehensively outmanoeuvred as he struggled with an ankle injury.
It was the most one-sided men’s semi-final in New York since the open era began in 1968.
Croatia’s Cilic, seeded ninth, had rolled his ankle injury in an earlier round and came up against the worst possible opponent, with Djokovic breaking his serve eight times.
“Marin was carrying an injury, he was courageous to come out and finish the match, so applause to him,” said Djokovic.
“I came out with good focus and good intensity and executed the game plan.”
It is the first time in his career that Djokovic has made all four major finals in a single year and he would be competing for the calendar Grand Slam on Sunday, had he not lost to Wawrinka at Roland Garros in June.
“It is a great achievement and I’m very proud of it,” he said.
