Jannik Sinner’s only US Open challenge left is measuring up to himself

As he gears up for the 2026 US Open, what does Jannik Sinner have left to chase?

I mean, the guy has already won five Grand Slams at 25 years old, he’s made almost $70 million in prize money alone, nobody doubts that he’s already among the greatest men’s tennis players to ever pick up a racket. Is this like how Orson Welles made Citizen Kane when he was 26 and thus everything after, while still impressive, just wasn’t quite as remarkable? Honestly, the whole “dominate men’s tennis for decades” schtick is tired and worn out. It’s all been done before; Novak Djokovic, Rafael Nadal, Roger Federer, been there, seen that. Get some new material.

Sinner still needs to win a French Open, I guess, since he’s still missing that in the career Grand Slam, but it won’t be solved in Queens. No, what I think Sinner is chasing is a level of individual dominance that has been, until now, unreachable. Becoming a god of tennis.

If you’re familiar with this kind of mythology, you’ll know that gods don’t play by everyone else’s rules. They don’t get hung up on things like physics or eating or the consequences of one’s actions. Most importantly, when they fight, they never lose to anyone … except other gods.

None of Federer, Djokovic or Nadal was ever actually unbeatable. Sure, they rarely lost to anyone other than each other, but three is a crowd, and there was still a very high level of variance (if you ignore the French Open) as to who could take home each Grand Slam. They also occupied slightly different territories in the tennissphere; Federer dominated the era before Djokovic really emerged, and Nadal planted his flag on clay and never gave an inch for almost two decades. It was a tremendous rivalry, one of the greatest in sports history, but it was never really … even.

Sinner could achieve even greater heights. There is only one man, Carlos Alcaraz, who is on Sinner’s level, and the two are on roughly the same timeline without any obvious surface advantages. The duopoly they’ve created could persist for another ten years, if not more, since gods do not lose to anyone except other gods. If there’s only two, then they can only really lose to each other.

Of course, neither have quite made it to Mount Olympus yet. Both must overcome the physical limitations of their greatness, with Sinner breaking down in the heat during the French Open and falling to Juan Manuel Cerundolo in maybe the biggest upset in tennis history. Alcaraz won the Australian Open, but missed both Roland Garros and Wimbledon with an injury. It is unclear if the two will be able to maintain the kind of health that let Federer and Djokovic dominate year after year.

Sinner in particular feels limitless if he can beat the heat. Alcaraz plays with a type of distilled reckless abandon; he knows what he’s doing, and his maximum output may be higher than the Italian’s, but there’s potential for dangerous things to happen. Sinner, meanwhile, is efficient and compact, able to produce the type of searing shots required to beat everyone from a much less explosive setup. I don’t know if it’s actually more sustainable, but it feels like it should be.

If you needed a number to explain Sinner’s greatness, it would be 80. In tennis, the best players win about 52 percent of all points. Because of how powerful serves are in the men’s game, it’s hard to do much better than that. Most other statistics like game winning percentage, set winning percentage, service point winning percentage, etc. get into the 60s for the best players. You’re not really supposed to get most of these into the 70s; Sinner, meanwhile, pushes them into the 80s.

In the last 52 weeks on tour, Sinner has won 92.7 percent of all matches he’s played. Alcaraz is at just over 88 percent, nobody else is even above 80. He is also uniquely built for complex five-set affairs, having won 81.5 percent of tiebreakers while no one else exceeded 70 percent. He’s won over 87 percent of all sets to Alcaraz’s 82 percent and (say it with me now) no one else is over 70.

There is no blemish on Sinner’s analytical resume. Being able to win 80-90 percent of the most important moments in tennis is such an absurd level of consistency that it would be foolish to bet on anyone else (other than Alcaraz, who’s right there with him). That is the argument for Sinner to be one of the gods of men’s tennis. He has a better win condition than anyone else. At the 2026 US Open, him not winning a set will be an aberration.
