Sinner beats Auger-Aliassime to face Alcaraz in US Open final

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.

World number one Sinner was almost perfect in the opening set, making just four unforced errors, leading to the feeling that another routine win was on the cards.

But errors began to creep into Sinner's game in the second and Auger-Aliassime, who was appearing in just his second Grand Slam semi-final and first since 2021, grew in confidence - feeding off the energy of the crowd to get a foothold.

Auger-Aliassime passed up three break points for the chance to lead 2-0 but went on to break for 5-3 before serving out for the set.

There had been no real indication that Sinner was carrying an injury until he left the court for treatment, although his first-serve accuracy had dropped slightly.

He landed just 10 of 25 (40%) in the third compared to 10 of 22 (45%) in the second set and 13 of 25 (52%) in the first.

Auger-Aliassime was unable to fully capitalise on any potential problem, though, and a break of serve at 5-3 was enough to take the set.

By the time the fourth began, Sinner appeared the fresher of the two - barring a few moments of resilience from his opponent.

Victory means Sinner is just the fourth player in the Open era to reach all four Grand Slam finals in a single season after Rod Laver, Roger Federer and Djokovic.

Sinner trails Alcaraz in their head-to-head record, losing nine of their 14 meetings, including three of their four encounters in 2025.
