Sinner Wins Paris Masters, Reclaims ATP No. 1

Jannik Sinner defeated Félix Auger‑Aliassime 6-4, 7-6(4) to win the Paris Masters for the first time. The title was Sinner’s first Masters crown of the year and his fifth overall in 2025, extending an indoor hard-court winning streak reported at 25–26 matches. The victory propelled him back to the top of the ATP rankings, though his hold on No. 1 is provisional because Carlos Alcaraz can still finish the year atop depending on results at the ATP Finals in Turin. Auger‑Aliassime’s defeat cost him a guaranteed spot at the season-ending ATP Finals. Sinner had reached the Paris final after a dominant 6-0, 6-1 semifinal win over Alexander Zverev, underscoring his strong late-season form.
