Jannik Sinner has pulled out of the 2026 US Open, saying he is “very sad and disappointed” after the knee problem that has kept him out of action since Wimbledon.

The world No 1 has not competed since defeating Alexander Zverev in the Wimbledon final last month, and his withdrawal now removes one of the leading names from the final Grand Slam of the season.

Sinner explained the decision in a statement posted on social media.

“Even though I have been working hard with my team and my medical staff, we have now had to make the difficult decision that I will not be able to compete at the US Open this year.

“We have been back on court in Monte Carlo over the last couple of days and have realised that I still need more time to recover from my right knee issue.

“I’m obviously very sad and disappointed, as New York has a special place in my heart.

“I was very much looking forward to coming back and playing in the electric atmosphere in front of the great fans there.”

The withdrawal means Sinner is the 15th player to pull out of the 2026 US Open across the men’s and women’s draws.

His absence adds another notable change to a tournament already affected by a string of withdrawals, with the men’s and women’s events both impacted.

Elena Rybakina’s run at the 2026 Cincinnati Open came to an abrupt end in the quarter-finals, and with it her chance to climb to world No 1 this week. The Kazakh retired while trailing 1-4 in the first set of her match against Iga Swiatek after an injury setback forced her to stop.

Rybakina later explained that a left ankle problem had been an issue for “a long period of time.” Speaking after the match, she said: “Of course, now I feel not the greatest, I couldn’t even push from the serve,” Rybakina said afterwards. “It’s painful to walk, and we will know more tomorrow when I do the MRI.

“It’s been bothering me for a long period of time. It was under control, but then after playing a lot of matches in Canada and coming here playing two matches in a row.”

The world No 2 started the tournament on 7,926 points in the Live WTA Rankings, leaving her 529 points behind Aryna Sabalenka, who began as the top-ranked player. That gap left the door open for Rybakina to move ahead, depending on how the Cincinnati event unfolded.

Sabalenka’s surprise fourth-round loss to Sara Bejlek changed the picture and left her on 8,575 points in the Live WTA Rankings. At that point, Rybakina would have taken over at No 1 if she had reached the final in Cincinnati.

Her quarter-final retirement, however, means she will update to 8,141 points, leaving her 434 points behind Sabalenka. The 26-year-old will remain at No 2, while she stays 1,136 points clear of third-ranked Jessica Pegula, who is through to the semi-finals in Cincinnati.

Legendary coach Rick Macci has offered a clear view on the ATP Tour race at the top of men’s tennis, saying he does not believe any current player will match the level set by Carlos Alcaraz and Jannik Sinner.

Since the start of 2024, Alcaraz and Sinner have been the sport’s defining names, sharing five of the last 11 Grand Slam titles between them after Novak Djokovic collected his 24th and most recent major at the 2023 US Open. Their grip on the biggest stages has continued in 2026, with Alcaraz winning the Australian Open and Sinner taking Wimbledon. Alexander Zverev, meanwhile, captured his first Grand Slam title at Roland Garros.

Alcaraz now owns seven major titles, while Sinner has established himself as a five-time Grand Slam champion.

Among the younger names being discussed as possible long-term challengers are Rafael Jodar and Joao Fonseca. In an exclusive interview, Tennis365 asked Macci whether he believes those players can eventually compete with the two leaders of the game.

Macci was willing to acknowledge their potential, but drew a firm line when it came to the very top. “Fonseca can definitely be in the mix,” said Macci. “A lot of those guys are going to go into the top five because they’re so young.

“But, the way Sinner plays – he has firepower off both sides, and he can produce quality off of quality. He’s hitting the ball 80 miles an hour eight times in a row, and holding the baseline.

“And his mind’s made of granite — that’s why he’s number one on the planet! He has the most important thing, he doesn’t have all the motor skills like Carlos.

“Alcaraz, he checks every box. The only time he gets in trouble is when he has too many options. But what a good situation… his toughest opponent, a lot of times, is in the mirror. It’s not the other guy.

“So, these other guys can make a cameo and be top five, but no one that I see right now is going to be in that mix [with Alcaraz and Sinner], because they still have a few things not like them — whether it be a little different movement, or maybe not as strong at this or that.

“Whereas, Alcaraz checks every box, and the way Sinner plays, especially in 2026, you can’t penetrate the guy on any surface.”

Macci’s perspective carries particular weight. He has coached five future world No 1 players: Serena Williams, Venus Williams, Jennifer Capriati, Maria Sharapova and Andy Roddick.
