Sinner wins to set up Alcaraz final at US Open
It will be the third consecutive meeting between the pair in a title decider after Alcaraz's French Open win in June was followed a month later by Sinner winning at Wimbledon.
Jannik Sinner came through a slight injury scare to win his US Open semi-final against Felix Auger-Aliassime and set up another tantalising Grand Slam final with Carlos Alcaraz.
It will be the third consecutive meeting between the pair in a title decider after Alcaraz's French Open win in June was followed a month later by Sinner winning at Wimbledon.
It is also the first time in the Open era that two players have contested three major finals in the same season and Sunday's match will also be for the number one ranking - which Sinner has held for 65 consecutive weeks.
Defending champion Sinner was far from his best but had enough to come through 6-1 3-6 6-3 6-4 on Arthur Ashe Stadium.
It means Sinner, 24, has won 26 of his 27 matches at Grand Slams this year - winning titles at the Australian Open and Wimbledon and reaching the final of the French Open.
Sinner rattled through the opening set but stumbled in the second, with an injury seemingly hindering him as a rejuvenated Auger-Aliassime drew level.
The Italian took a medical timeout before returning for the third set and settled back into a rhythm without ever hitting top form.
He will take on world number two Alcaraz in Sunday's showpiece after the Spaniard overcame Novak Djokovic 6-4 7-6 (7-4) 6-2 earlier on Friday.
"Sunday is a very special day and an amazing final again," said Sinner, who added in his post-match interview that his injury was "nothing too bad".
He continued: "We'll see what's coming. I feel like our rivalry started here playing an amazing match [in 2022, when Alcaraz beat Sinner in the quarter-finals]. We are two different players now, with different confidence too.
"We've played each other a lot, we know each other very well."
