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.
Russian second seed Medvedev had earlier kept alive his hopes of a first major title with a 6-4 7-5 6-2 win over Canadian Felix Auger-Aliassime.
Djokovic then recovered from falling a set behind to win 4-6 6-2 6-4 4-6 6-2.
He now has the chance to win a record 21st men’s Grand Slam singles title.
