Shortly after Alcaraz wove his magic to dismantle 24-times Grand Slam champion Novak Djokovic on Arthur Ashe Stadium, the usually machine-like Sinner misfired at times but prevailed to ensure a third successive major final with the Spaniard.

The Italian world No 1 faced brief resistance in the fifth game of the contest but dialled up the intensity to hold and wrapped up the lopsided opening set when Auger-Aliassime sent a backhand wide.

Auger-Aliassime settled his nerves in his second New York semi-final, breaking for a 5-3 lead in the next set en route to levelling the match, before going toe-to-toe with Sinner in the third set, only for the momentum to shift again.

Sinner, who took a medical timeout for an unspecified issue earlier, found his groove to close out the third set and staved off a strong challenge from his reinvigorated Canadian opponent with some clutch serving in the next set to advance.
