Jannik Sinner Wins Paris Masters, Reclaims ATP World No.1 Ranking

Jannik Sinner claimed his first Paris Masters title in 2025 by defeating Felix Auger-Aliassime in straight sets, 6-4, 7-6(4), without dropping a set throughout the tournament, a feat last achieved by Carlos Alcaraz in 2023. This victory marked Sinner's fifth ATP Masters 1000 crown and his return to the World No. 1 ranking, surpassing Carlos Alcaraz, who dropped to 11,250 points following an early exit. Sinner's win capped a powerful comeback season, having secured five titles in 2025 despite missing three months due to a doping-related suspension. Auger-Aliassime, seeking his biggest title and ATP Finals qualification, was runner-up for the second time in a Masters 1000 event but remains a strong contender for the season-ending tournament. The win also extended Sinner's impressive 26-match indoor winning streak, underscoring his dominance on indoor hard courts. The ATP Finals will be critical in the battle for year-end No. 1, with Sinner defending his title and Alcaraz needing strong performances to reclaim the top spot.
