ATP Tennis Coaching US Open
Jannik Sinner to Travel Solo Coach at US Open as Darren Cahill Takes Break
Jannik Sinner will defend his US Open title with one coach as Darren Cahill takes a break.

Jannik Sinner will head into the US Open title defense with a leaner coaching team, as Darren Cahill will not be traveling to New York. Cahill, who announced his intention to retire from coaching after the 2025 season, will take a short break during the final Grand Slam of the year. This was confirmed by Simone Vagnozzi, who leads the coaching unit for Sinner, and remains cautious about Cahill’s future beyond this period.
Cahill’s retirement plans had come under speculation, with whispers he might reconsider staying on in 2026. Vagnozzi stated, “Honestly, nothing’s certain at the moment. But we’ll all be happy if Darren stays.”
Vagnozzi, who has jointly coached Sinner alongside Cahill since 2022, will continue to guide the technical and tactical preparations. The coaching team also welcomed back controversial fitness trainer Umberto Ferrara this week. Ferrara was previously part of Sinner’s team but was let go following the player’s positive clostebol tests in March 2024. His return was confirmed with immediate effect to aid in tournament prep, including for the Cincinnati Open and US Open.
Together, Cahill and Vagnozzi have overseen some of Sinner’s most significant career milestones: his maiden Grand Slam victory at the 2024 Australian Open, reaching world No. 1 in June, successfully defending his Australian Open title earlier this year, winning the 2024 US Open, and bouncing back from a narrow loss to Carlos Alcaraz at Roland Garros to claim Wimbledon. Vagnozzi described the partnership with Cahill as vital, stating, “I have to say that I’m so lucky to have met someone like Darren, both professionally and personally. We connected immediately, and that undoubtedly helped us in our journey. It’s never easy to find that chemistry, but we’ve always prioritised Jannik’s interests.”
The team’s complementary roles allow Vagnozzi to focus on the more technical and tactical aspects, while Cahill handles mental and emotional support, ensuring the player hears one unified voice throughout his campaign.

Becker: Sinner’s serve and predictability cost him in US Open final
Becker said Sinner was ‘predictable’ and weaker on serve as Alcaraz won the US Open final again now

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 Hangzhou Open arrives as the ATP returns to Asia for its autumn swing, with a notable entry list for an ATP 250 event. The tournament, staged again after its 2024 edition in which Marin Cilic defeated Zhang Zhizhen in the final, will take place in the 8,000-seat stadium and promises a compact week of singles action.
Top seed duties fall to world No 14 Andrey Rublev, who is entered at the event for the first time. He is joined at the head of the field by compatriot Daniil Medvedev, a former world No 1 who is competing in his first tournament under new coach Thomas Johansson. Medvedev has dropped to 18th in the ATP Rankings this season and is opting to focus on ATP events rather than other team competitions.
Alexander Bublik, ranked No 19, is also entered and arrives on the back of his best season to date, targeting a fourth title of 2025. The quartet of top seeds is completed by world No 39 Corentin Moutet, the only other top-40 player currently in the entry list.
Seeds five through eight include Camilo Ugo Carabelli, Roberto Bautista Agut, Adrian Mannarino and Learner Tien. Defending champion Marin Cilic returns to defend his title, and Matteo Berrettini is among those listed as making a comeback following recent injury issues. Other names in the entry list include Tomas Martin Etcheverry, Damir Dzumhur, Aleksandar Kovacevic, Matteo Arnaldi and David Goffin, among others.
As an ATP 250 tournament, the champion will receive 250 ranking points. While the ATP has not published an updated round-by-round points table for 2025, last year’s distribution awarded 165 points to the runner-up, 100 to semifinalists, 50 to quarterfinalists, 25 to second-round winners and no points for a first-round exit. The event carries a total prize-money purse of $1,019,185, up slightly from 2024; Cilic earned $152,240 for lifting the title last year.
The 28-player main draw begins on Wednesday, September 17 and concludes with the final on Tuesday, September 23. The top four seeds—Rublev, Medvedev, Bublik and Moutet—will receive byes into the second round. Wildcards and qualifiers will be confirmed ahead of the draw ceremony.

US Open 2025: form shifts, surprise runs and a mixed doubles renaissance
US Open 2025: surprises, career milestones, doubles revival and mixed fortunes across the draws fans

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.”
