Three-time champion Serena Williams ended the US Open hopes of world number one Caroline Wozniacki with a commanding display in their semi-final.
The 29-year-old American belied her seeding of 28 as she powered through 6-2 6-4 on the Arthur Ashe Stadium.
Williams has yet to drop a set at Flushing Meadows as she closes on a 14th Grand Slam title of her career.
She will play ninth seed Sam Stosur in the final after the Australian beat Germany's Angelique Kerber 6-3 2-6 6-2.
The women's final will take place at 2130 BST on Sunday after bad weather earlier in the week caused the schedule to be reorganised.
"I really feel like I don't have anything to lose," Williams said after her win. "I have beaten all the odds.
"Six months ago I was in the hospital and now I'm in the final. So I feel like, regardless of the result, I have been a champion for everyone out there who is fighting against all odds and staying positive."
Williams has been a strong favourite for the title throughout the tournament, despite a world ranking of 27th as she makes her way back after a serious foot injury last year.
Wozniacki remains dogged by questions about her lack of a Grand Slam title and the 21-year-old Dane never looked like getting past Williams.
An early break point was not converted and after Williams broke serve in a lengthy fourth game, only a medical time-out for attention to her heavily strapped foot really threatened her.
Wozniacki got one break back in game seven but Williams immediately hit back to wrap up the set after 46 minutes, making 15 winners to none from the Dane.
The American's 24th winner of the night was a beautiful forehand that set up three more break points at 2-1 in the second set, and Wozniacki cracked with a double-fault.
Williams betrayed some nerves with a loose game when serving for the match, double-faulting on break point, but she broke straight back to reach her first Grand Slam final since winning Wimbledon last year.
Wozniacki was upbeat despite the defeat, and inevitably was asked about being top of the world rankings having not won a Grand Slam.
"I'm still number one in the ranking. No-one can take that away from me for now. It's definitely been a successful year for me.
"I cannot complain. I won six titles. I have made two semi-finals of Grand Slams."
The first women's semi-final had been controversially moved to the Grandstand court with the men's semi-finals rescheduled for Ashe.
Stosur had indicated her unhappiness at playing a Grand Slam semi-final on effectively the third show court but she survived a late fightback to see off the unseeded Kerber.
"It's a dream come true," said the 27-year-old, who regained her composure after failing to serve out the match at her first attempt. "This is something I've wanted to do since I first started playing tennis.
"I have been playing for nearly 20 years now, so it's been a long run to try and get to this point."
Stosur becomes the first Australian woman to reach the US Open final since Wendy Turnbull in 1977.
