Dominic Thiem has advanced to his first U.S. Open final, beating Daniil Medvedev 6-2, 7-6 (7), 7-6 (5).
The second-seeded Thiem will play Sunday against No. 5 seed Alexander Zverev, with the winner earning his first Grand Slam title.
Thiem has had three previous chances, losing back-to-back French Opens to Rafael Nadal in 2018 and 2019 and this year's Australian Open to top-ranked Novak Djokovic.
He got another opportunity by overcoming a 5-2 deficit in the third set after he had been treated for a right Achilles tendon injury after the second set.
Medvedev, the runner-up to Nadal last year in Flushing Meadows, hadn't dropped a set coming into the semifinals.
