World number one Novak Djokovic won a gruelling five-setter against Alexander Zverev to set up a US Open final against Daniil Medvedev and keep his bid for a calendar Grand Slam on track.
He now has the chance to win a record 21st men's Grand Slam singles title.
Victory over Medvedev would move Djokovic clear of the 20 majors won by Roger Federer and Rafael Nadal.
History-chasing Djokovic would also become the first man to win all four majors in the same year since Rod Laver in 1969.
