Five-times champion Roger Federer reached his first U.S. Open final in six years as he raced past fellow Swiss Stan Wawrinka 6-4 6-3 6-1 in the semi-finals.
The second-seeded Federer, in remarkably sublime form at the age of 34, has not dropped a set in his formidable Flushing Meadows run and never let up the pressure on fifth-seeded French Open winner Wawrinka in a 92-minute demolition.
The trouncing set up a delectable one-two showdown in Sunday's final against Australian Open and Wimbledon winner Novak Djokovic.
The top-seeded world number one from Serbia was even faster booking a berth in his fourth grand slam final of the year with a 6-0 6-1 6-1 romp over defending champion Marin Cilic of Croatia, who was hampered by an ankle injury.
Federer, the all-time grand slam singles king with 17 titles, will be gunning to add to his record slams haul for the first time since his 2012 Wimbledon triumph.
"Obviously, I'm very happy. It's been a great tournament so far," Federer, who won five straight U.S. crowns from 2004 and was runner-up in 2009, told the Arthur Ashe Stadium crowd.
"I've tried very hard the last six years to get back in another final."
The evergreen Swiss was not broken by Wawrinka as he improved his head-to-head edge to 17-3 while avenging a quarter-finals loss to him this year at Roland Garros.
Federer has been serving beautifully, registering 10 aces against Davis Cup team mate Wawrinka, and hoped he had another dominant match in him.
"I'm serving very well, playing positive tennis, going for my shots and it seems to work," he said. "I'd love it to work just one more time this year."
