Boris Becker offered a blunt assessment after Jannik Sinner was unable to defend his US Open title, falling 6-2, 3-6, 6-1, 6-4 to Carlos Alcaraz in Sunday’s men’s singles final. The loss cost Sinner the championship and allowed Alcaraz to reclaim the world No 1 ranking.

Becker pointed to a specific weakness that Alcaraz exploited throughout the match. “From the first minute to the last, Alcaraz was clearly better than all the other players and even better than Sinner,” said Becker. “In the final, he was clearly the boss. He played tennis from another planet and deserved to win the tournament.

“The big difference I noticed in this duel was on serve; Sinner was clearly weaker, and that’s unforgiving, if he has a real weakness, it’s this one.”

The defeat extended Alcaraz’s dominance in their rivalry: it was Sinner’s seventh loss to Alcaraz in eight meetings since the start of 2024, leaving Alcaraz with a 10-5 advantage in the head-to-head. During that period Sinner lost only four matches to players other than the Spaniard. Alcaraz’s victory also brought him level with Becker on two US Open titles and six Grand Slam trophies overall.

Becker said he had expected more from Sinner and felt the Italian had not advanced in the ways Alcaraz had. “I am one who always thinks to tell the truth. I was a little disappointed. I expected more.

“But of course I was not disappointed by Alcaraz. Because he really played tennis better today than a year ago. He had more variations, he had speed changes. He played serve volley. He played backhand slice. He played forehand where you don’t see the ball.

“And I think Sinner, for the first time, he stood still with his game. He is now predictable. You know exactly what always happens. And it’s not as bad that I see it that way. It’s worse for him that Alcaraz sees it that way.

“And I think for the first time that Alcaraz really took a step forward. And Sinner stayed the same. He partly didn’t know how to win the points. Except Alcaraz hit the ball.

“In his press conference after the match, Sinner, always said very honestly, that he [Alcaraz] has developed further in tennis and I have not. And I think it’s great that he says that. But that’s how I felt it.

“There was never a discussion for me, even after the second set, who would win this match in the end. And I didn’t see that in any other final between the two.”

Both players are scheduled to compete at the Shanghai Masters next month, where Sinner will aim to defend the title he won in 2024.

The 2025 US Open produced as many storylines beyond the finals as it did inside them. Across three weeks there were returns to form, stinging exits and a clear surge in interest for doubles.

Amanda Anisimova recovered impressively from her 6-0, 6-0 loss at Wimbledon to reach the semifinals in New York and climb to a career-high No. 4. By contrast Alexander Zverev, seeded No. 3, exited in the third round to No. 25 Felix Auger-Aliassime, extending his frustration at Grand Slams.

Carlos Alcaraz asserted himself in the semifinals, pulling away from 38-year-old No. 7 seed Novak Djokovic. Djokovic, a record 428-week world No. 1, returned to competitive form after Wimbledon and completed the full set of major semifinals in 2025, rising back to No. 4. Taylor Fritz, the defending finalist and No. 4 seed, was the only American man to reach the fourth round before a loss to Djokovic. Frances Tiafoe, Tommy Paul and Ben Shelton all fell earlier, with Shelton forced to retire in his third-round match due to a shoulder injury.

Holger Rune and Stefanos Tsitsipas disappointed, with Rune losing in round two to Jan-Lennard Struff and Tsitsipas losing to Daniel Altmaier after a heated postmatch exchange that included this line from Tsitsipas: “Next time, don’t wonder why I hit you, okay? No, I’m just saying if you serve underarm. . .”

Felix Auger-Aliassime emerged as a major story, defeating Zverev and Alex de Minaur before his run ended in the semifinals. “Well, a lot of things,” FAA said. “A lot of things. because obviously there’s the level, like the way I’m serving, the way I hit the forehand, the way I’m moving around the court, the backhand too. . . I think on top of that it’s just, yeah, the belief, the mentality, the conviction in myself that I have what it takes to win these types of matches.”

Naomi Osaka reached her first major semifinal since 2021 and credited coach Tomasz Wiktorowski: “He’s like always very proud and encouraging,” she said of him. “I feel like it kind of creates a safe space for me to, like, you know, be able to express myself and my tennis.”

The USTA’s reimagined Mixed Doubles Championship and Fan Week drove attendance figures, with Fan Week drawing 239,000 and the mixed event bringing 78,000 over two days, helping push total attendance past 1,000,000. Joe Salisbury observed: “It (the singles star-studded Mixed Doubles event) got the fans engaged in watching more doubles. So I think for that part it was a good thing. For the event, the last sort of eight, nine days, I think it’s been good. More fans were coming to watch.”

Donald Trump attended the US Open men’s singles final as a guest of Rolex and offered praise for the two players after the match. His arrival required additional security checks that delayed the scheduled start by around 40 minutes, and some spectators did not make it into Arthur Ashe Stadium until after play had begun.

Carlos Alcaraz produced a scintillating performance to defeat his Italian opponent in four sets, securing a second US Open crown and reclaiming the world No 1 ranking. The result capped a third consecutive Grand Slam final contested by the pair and supplied the high-level tennis Trump said he had come to see.

A long-time tennis fan, Trump was a regular at the US Open for much of three decades but had not attended the tournament since 2015. His last appearance came shortly after launching his first presidential campaign, when he watched the women’s singles quarter-final between Venus and Serena Williams and on that occasion was widely booed by the crowd.

Asked about his experience during a press call this week, Trump praised both players and his visit. “Well, I loved it,” said Trump. “First of all, the two players [Alcaraz and Sinner] have unbelievable talent. It just seemed that they hit the ball harder than I’ve ever seen before. Incredible talent — and I enjoyed it.

“I used to go all the time, but lately it’s a little bit more difficult to go. I really enjoyed it.”

Video recorded inside the stadium suggested there was booing when the president appeared on screen, though Trump said the fans were welcoming during his time at the match. He added: “They were really nice, the fans were really nice. I didn’t know what to expect.

“Usually, you would say that would be a somewhat progressive — as they would say, nowadays — crowd. Some people would call it liberal.

“But, we’ll use the word they like to use, progressive, but they were great, the fans were great.”
