Carlos Alcaraz continued his stunning season at the US Open, where he claimed his second Grand Slam title of 2025.

Alcaraz is now a six-time Grand Slam champion, while the Spaniard boasts 23 ATP Tour titles in his glittering career so far.

Seven of those titles have arrived this season alone, with his success starting back in Rotterdam in February.

Thanks to his continued success, Alcaraz has surpassed $50million in prize money for his career, with that figure set to grow rapidly in the years to come.

It remains to be seen just who can stop his momentum right now, with Alcaraz also returning to top spot in the world rankings after his run in New York.

Jannik Sinner has, of course, managed to slow down such momentum, notably beating the Spaniard in the Wimbledon final.

But he represents just one of six players to defeat Alcaraz this season, with the new US Open champion currently boasting a 2025 win-loss record of 61-6.

The Wimbledon defeat to Sinner represents his most recent loss, arriving long after Holger Rune beat Alcaraz in the Barcelona Open final.

Before that, David Goffin shocked him in his first match at the Miami Open, with Jack Draper doing the same in the semifinals of Indian Wells.

Jiri Lehecka is also on the list of major upsets, knocking him out of the Qatar Open at the quarterfinal stage.

And in his first tournament of the 2025 season, Alcaraz fell in the quarterfinals of the Australian Open at the hands of Novak Djokovic.

Carlos Alcaraz’s 2025 ATP lossesWho has beaten Jannik Sinner on the ATP Tour this season?

In stark contrast, Sinner has been a constant victim of the Spanish star this season, a trend that continued at the US Open.

Sinner has a real Alcaraz problem, with four of his five losses in 2025 arriving against his main rival, while the other came against Alexander Bublik.

The Kazakh ace shocked him in Halle, while Alcaraz won their meetings at Roland Garros, Rome, Cincinnati and New York.

But the Italian also has a hugely impressive win-loss record this season, with 37 wins accompanying those five defeats.

And even though six players have managed to take something from the new world number one, Sinner remains the biggest threat to his current dominance.

And that means that another ATP player should now be desperate to step up and mount a real challenge against the duo.

They’ve combined to win each of the last eight Grand Slams, a run that could very easily continue in 2026.
