Carlos Alcaraz ended the reign of Jannik Sinner with a 6-2 3-6 6-1 6-4 victory to claim the U.S. Open title again on Sunday (September 7) and tighten his grip on the era-defining rivalry between the torch-bearers of the men's game.

In a perfect echo of the triumph that first propelled him to the world number one spot in 2022, Alcaraz's New York title took him back to the top of the rankings as the 22-year-old Spaniard displaced Sinner and lifted his Grand Slam trophy haul to six.

It made him the second youngest man in the professional era that began in 1968 to win six majors, after Bjorn Borg, and also snapped Sinner's staggering 27-match winning run at hardcourt majors to dent the Italian's sparkling season.

The Spaniard, who turned heads with his surprise buzz cut at the start of the tournament, departs as the toast of New York on a 13-match winning streak with seven titles and only six defeats in 2025.

As grey clouds hovered over the iconic Arthur Ashe Stadium, Alcaraz continued to deliver the sunshine tennis that has lit up Flushing Meadows over the last fortnight, consolidating an early break by faking a drop to hit a winner that wrong-footed Sinner.

He beamed after pulling off an outrageous half-volley at the net and wrapped up the opening set shortly afterwards, finishing it off with a big serve that Sinner crashed into the net as the Italian's metronomic precision briefly deserted him.

With U.S. President Donald Trump watching from a luxury box in the stands and adding another layer of spectacle to the third straight Grand Slam final between the duo this year, Sinner hit back to take the next set after saving an early break point.

After dropping his first set of the slam, Alcaraz turned up the power and bludgeoned his way to a 5-0 advantage in the third set before Sinner got on the board, and the Spaniard closed it out with a monster serve.

Sinner conjured up two breathtaking volleys in the opening game of the fourth set to roaring applause and held serve after being pushed to the limit again, but he cracked under pressure and handed the crucial break to Alcaraz in the fifth game.

Resembling a flamingo in full flight in his bright pink vest, Alcaraz soared ahead to secure the victory on his third match point and celebrated by raising his fists before a warm embrace with his rival and wild celebrations with his team.

A dejected Sinner was left to contemplate another Grand Slam final loss to Alcaraz this season after coming up short in their French Open epic in June, although he beat the Spaniard to take his Wimbledon crown the following month.

"Well, it's, as I said, for me it's great. When you achieve the goals you set up yourself at the beginning of the year, it feels amazing. Since I got the chance to recover the No. 1, it was one of the first goals that I had during the season, just to try to recover the No. 1 as soon as possible or end the year as the No. 1. For me, achieve that once again, it is, as I said, it is a dream. Doing in the same day as getting another Grand Slam feels even better. It's everything I'm working for, and I'm really happy to be able to live these experiences."

Obviously right after that I didn't practice, so I just took a week for myself not doing anything at all. But right after the match it felt like, okay, when I start practicing, I just wanted to practice this, this, this, and this. Sorry, guys, but I just thought about the specific things I want to improve if I want to beat Jannik. So I just spent two weeks before Cincinnati just practicing specific some things about my game that I need or I felt like I need to improve if I want to beat Jannik."

"Well, I think it's going to be great. It's my first goal, to be honest. When I just go to the preseasons to what I want to improve, what I want to achieve, Australian Open is there. It's the first or second tournament of the year, and it is always the main goal for me to complete a career Grand Slam, calendar Grand Slam. So it's going to be great.

If I do first or second for me, to be honest, I don't mind. I just wanted to complete it. Obviously I'm going to try to do it next year, but if it is not next year, hopefully in two and three and four. So I will try to complete it.

If he (Sinner) does it first, it's a great achievement, but for me, all I want to think is to complete it no matter when."

You know, I felt like he was doing everything slightly better today, especially serving, both sides, both swings, very clean. And yeah, I think that's it, you know. I give lots of credit to him, you know, because he handled the situation better than I did. Yeah, he raised his level when he had to. So yeah, I mean, I'm still proud of myself, about the season I'm playing and making. But, yeah, he played better than me today."

"He's just a different player, you know? It's very simple, you know? He's a different player. He doesn't have, you know, weaknesses, for example, which maybe some players, they have weaknesses. Then you try to play tactically in a way. But I feel like mostly we have some history, you know, some head-to-heads, some different surface battles now. And think that makes it quite interesting.
