Jannik Sinner has added another remarkable chapter to his rise by capturing the ATP Finals for the second straight year. The Italian defeated long-time rival Carlos Alcaraz in the 2025 title match, repeating the success he enjoyed in 2024 and extending a season already packed with milestones.

With this victory, Sinner pushed his streak of indoor wins to 31 consecutive matches, overtaking Roger Federer’s mark of 29 and moving within reach of the 32 recorded by Ivan Lendl between 1980 and 1983. His last defeat on an indoor hard court dates back to the 2023 Finals, when he fell to Novak Djokovic.

The Turin event brought another extraordinary statistic: Sinner has now won 20 straight sets at the ATP Finals. Over the last two editions he has not conceded a single set, becoming the only player ever to complete the round-robin stage without dropping one in two consecutive years.

Beating Alcaraz also lifted him to 24 career titles, six of which came this year despite a three-month break linked to the Clostebol case. Out of the 12 tournaments he entered in 2025, he reached ten finals, falling short only in Halle - where he lost to Alexander Bublik - and in Shanghai, where cramps forced him to retire. He now joins Roger Federer and Novak Djokovic as one of the few players to reach all four Grand Slam finals and the ATP Finals title match in the same season.

Perhaps the clearest sign of his dominance came on serve: before Alcaraz managed to break him early in the second set of Sunday’s final, Sinner had held 64 service games in a row. With 15 wins in 17 matches played at the ATP Finals overall, he boasts an 88.24% winning percentage, surpassing Ilie Nastase’s 88% record.

The financial milestone is no less striking. With the 2025 crown, Sinner took home $5.07 million, the highest prize money ever awarded for a single ATP event, part of a total purse of $15.5 million.
