A sorpasso so longed for yet unattainable for a long time. That is what Carlos Alcaraz aims to achieve in this US Open 2025, a tournament where he holds a significant margin to add points to the ATP ranking. The Spanish player leads in terms of results in 2025, but he could surpass Jannik Sinner in the official ranking that dictates the weeks as No. 1 and the years ending in that position.

It should not be seen as an end goal but as a consequence of hard work. However, returning to the number 1 spot in the ATP ranking is something that excites Carlos Alcaraz greatly, as he has expressed in recent weeks. Some months ago, the Spanish player seemed poised to achieve it, especially with the suspension that kept Jannik Sinner off the courts for three months. However, shortly after, Alcaraz stepped up his game and made more than enough merits to return to the top of the list, a feeling he hasn't experienced for almost two years.

- Alcaraz has not been the world number 1 since August 28, 2023

While Alcaraz currently dominates the ATP Race, leading Sinner by 1,890 points, suggesting good prospects to end the year in that position, Carlos wants to seize the top spot in the ATP ranking now. This ranking reflects the past 52 weeks and determines the weeks as No. 1.

Presently, Jannik still leads seemingly with an iron grip, holding a similar advantage of 1,890 points. It may seem like a significant gap, but upon closer inspection of their standings, it is evident that this lead could be narrow, even at the US Open 2025. Alcaraz relies on himself to leave New York as the world number 1, as winning the tournament would regain him that position. However, Sinner is also in that position, and there are many other variables to consider.

It is crucial to note that Jannik Sinner defends 2,000 points for winning the title in Flushing Meadows last year. Meanwhile, Carlos Alcaraz will virtually lose only 50 points at the start of the event, earned from reaching the second round in the 2024 edition when he was defeated by Van de Zandschulp.
