This will be the battle for the number 1 spot in the ATP ranking between Sinner and Alcaraz until the US Open
The number one solidifies his reign on the circuit after his success at Wimbledon, but now begins the North American hard court tour where he must defend many points until reaching New York.
There is no one who can challenge the king of the circuit. Both on the court and in the rankings, Jannik Sinner dominates with an iron fist. This was evident in the final of Wimbledon 2025 against Carlos Alcaraz, where he imposed a level of tennis too high for the Spaniard. As a result of this achievement in London, the Italian extends his lead in the world rankings. Currently, he has 3430 points, a considerable distance, but now twists and turns lie ahead for the 23-year-old.
The world number one will land in North America, after a well-deserved break, to face a tour where he will be the main focus of attention, not only due to his success at Wimbledon but also because he has to defend his titles at Cincinnati and the US Open, under the watchful eye of Carlos Alcaraz, who only has 60 points to defend.
No risk of relinquishing the crown until the start of the US Open
Nevertheless, Sinner can breathe easy after the significant boost to his ranking, ensuring 100% that he will arrive as the world number one at the US Open, thus adding 65 consecutive weeks as the circuit's king before commencing the New York major.
However, if Alcaraz aims to dethrone the Italian in the future, he must arrive at the last Grand Slam of the season as close as possible to Sinner. To achieve this, he must achieve a better result in Toronto and Cincinnati than the world number one, who is defending quarters in Canada and the title in Ohio.
Alcaraz, with the intention of narrowing the gap as much as possible before New York
In the best-case scenario for the Murcian, if he were to triumph at the Toronto and Cincinnati Masters 1000 and Sinner were to lose all his points, something very unlikely given his current form and hard-court skills, he would gain 1990 points while the Italian would drop 1180, leaving the Murcian just 260 points behind . However, it should be noted that for this hypothesis to come true, Sinner would have to lose in both his debuts in Canada and Cincinnati, and Alcaraz would have to win both.
Another possibility is that he does not cut as many points, but enough to maintain some chance at the US Open or just at the end of it. Yet, it is essential for the El Palmar native to win the next two Masters 1000 if he wants to have a shot.
In conclusion, Jannik Sinner has a firm grip on his number one status until Sunday, August 24, when the US Open begins, from then on, any shift is possible considering he cannot earn points while defending his title, while it is unquestionable that Alcaraz will give it a try. However, we will have to wait for a couple of weeks to see how the two best tennis players in the world fare in their battle for circuit supremacy.
