The 2025 US Open men's singles final between Jannik Sinner and Carlos Alcaraz will double as a straight shootout for the world No. 1 ranking.
Sinner has owned the top spot in the ATP rankings since he debuted at No. 1 last June, with his reign currently at 65 weeks. Out of the 29 No. 1s in history (since 1973), only four others lasted at least 52 weeks in their debut stint: Roger Federer, Jimmy Connors, Lleyton Hewitt and Novak Djokovic.
Alcaraz is after a repeat of his 2022 US Open triumph in more ways than one. Not only is he bidding to beat Sinner, like he did in that year's quarterfinals en route to his maiden major trophy, he'll also once again seek to secure the No. 1 ranking by finishing first in Flushing.
The Spaniard famously became the youngest world No. 1 in history at 19, when he beat Casper Ruud in the 2022 final. He went on to earn year-end No. 1 honors and to date has spent a total of 36 weeks at No. 1.
Entering this year's US Open final, the ATP Tour's Live Rankings list Alcaraz 60 points clear of Sinner, 10,840 to 10,780. But that will count for nothing if Sinner scores the 700 points on offer in the trophy round.
