Jannik Sinner becomes youngest man in Open Era to reach all four Grand Slam finals in one season

Jannik Sinner has booked his spot in the US Open final by battling past Felix Auger-Aliassime in the semifinals on Friday night, 6-1, 3-6, 6-3, 6-4.

And with that four-set victory, Sinner has made history.

Having just turned 24 a few weeks ago, he's the youngest man in the Open Era to reach all four Grand Slam finals in one season.

So far this year he's won the Australian Open, finished runner-up to Carlos Alcaraz at Roland Garros, and won Wimbledon.

He's the fourth man in the Open Era to reach all four Grand Slam finals in one season, after Rod Laver, Roger Federer and Novak Djokovic. Federer held the previous record for youngest man in the Open Era to achieve the feat, doing it a few weeks after his 25th birthday in 2006.

MEN TO REACH ALL FOUR GRAND SLAM FINALS IN ONE SEASON IN OPEN ERA

• Rod Laver [1969]
• Roger Federer [2006, 2007, 2009]
• Novak Djokovic [2015, 2021, 2023]
• Jannik Sinner [2025]

Sinner had cruised past Auger-Aliassime in the quarterfinals of the Masters 1000 event in Cincinnati three weeks ago, 6-0, 6-2, but Auger-Aliassime had won the pair's two other career meetings, in 2022, and after another lopsided first set in Flushing Meadows on Friday night, he began playing like he did in those other previous encounters.

The Canadian stayed on serve with Sinner through most of the second set until right near the end, when he pounced, breaking for 5-3—he then served the set out at love, dusting it off with back-to-back aces.

Sinner bounced back, though, grabbing one break in each of the last two sets—in the sixth game of the third set and the fifth game of the fourth—en route to a hard-fought win after three hours and 31 minutes.

The world No. 1 finished with 33 winners to 22 unforced errors.

"Me and Felix, we played the last tournament and he is a completely different player," Sinner said afterwards. "He was serving much better, hitting every shot much better. So it was a very tough match today.

"But obviously I'm very, very happy."

Also, Sinner—who's through to his fifth straight Grand Slam final, a run that began at last year's US Open—is just the fourth man in the Open Era to reach the final at five consecutive majors. The first three men to do it are exactly who you would expect: Federer, Rafael Nadal and Djokovic.

And awaiting Sinner in the US Open final is exactly who you would expect, too, given how 2025 has been playing out—he'll face Alcaraz, who defeated Djokovic in straight sets in the first semifinal of the day.

Sinner and Alcaraz will play in a third straight major final on Sunday.
