10 sensational things Jannik Sinner achieved by winning this year's ATP Finals in Turin

Jannik Sinner was in lethal form at this year's ATP Finals in Turin, storming to the title without dropping a set, and finishing it off with a hard-fought 7-6 (4), 7-5 victory over Carlos Alcaraz.

With an event as big as the ATP Finals, there's always a lot on the line—here are 10 things the Italian achieved with his latest triumph:

He's just the third player ever to win multiple ATP Finals titles on home soil, having triumphed in Turin last year, too. The first two players to do that were John McEnroe, who won the tournament three times in New York City in 1978, 1983 and 1984, and Boris Becker, who won the event twice in Frankfurt in 1992 and 1995.

He's just the second player ever to win multiple ATP Finals titles without dropping a set. He didn't lose a set en route to the title last year, either. The only other player to achieve that feat was Ivan Lendl, who actually did it three times in 1982, 1985 and 1986.

He now has the BEST career winning percentage in ATP Finals history, with a minimum of 10 matches played. Going into the final, he was in second place at .875 (14-2), trailing only four-time champion Ilie Nastase's .880 (22-3). But his victory over Alcaraz in the final bumped him up to .882 (15-2), and into first place.

He finishes 2025 with three of the five biggest titles of the year. For the first time ever, two players split the four majors of a season evenly, 2-2, and then clashed in the final of the ATP Finals to break the tie—and Sinner came out on top this time against Alcaraz.

He also finishes as the only player to defeat Alcaraz twice this year. Alcaraz faced 15 different players multiple times this year, and Sinner was the only one of them to beat him twice. And it would have been three times if the Italian had converted one of his three match points in their epic Roland Garros final.

He's now won five of his last six matches against No. 1s. He's now 5-2 overall—2-0 against Alcaraz while the Spaniard is No. 1, and he was 3-2 against Novak Djokovic while the Serb was No. 1.

• l. to Djokovic in '21 Monte Carlo 2nd Rd, 6-4, 6-2
• d. Alcaraz in '23 Miami SFs, 6-7 (4), 6-4, 6-2
• d. Djokovic in '23 ATP Finals RR, 7-5, 6-7 (5), 7-6 (2)
• l. to Djokovic in '23 ATP Finals RR, 6-3, 6-3
• d. Djokovic in '23 Davis Cup SFs, 6-2, 2-6, 7-5
• d. Djokovic in '24 Australian Open SFs, 6-1, 6-2, 6-7 (6), 6-3
• d. Alcaraz in '25 ATP Finals F, 7-6 (4), 7-5

He finishes the year with as many titles as losses, the only man to achieve that feat this year. The Italian clinched that stat by winning the ATP Finals—he wraps up 2025 with a 58-6 record and six titles, having previously won the Australian Open, Wimbledon, Beijing, Vienna and Paris before ultimately triumphing in Turin.

He's just the fourth man in the Open Era to finish consecutive years with a winning percentage of 90% or higher. He was .924 in 2024 (73-6) and .906 in 2025 (58-6). The first three men: Bjorn Borg (1977-1980), Lendl (1985-1987) and Roger Federer (2004-2006).

He's now up to 10 career indoor titles—that's not just the most for any man born in 2000 or later, it's the most for any man born in 1990 or later. And it's no surprise given his penchant for indoor tennis—he finished 2025 on a 15-match indoor winning streak that brought him back-to-back-to-back titles at Vienna, Paris and the ATP Finals. He won 30 of his last 31 sets of the year, too, only losing a set to Alexander Zverev in the Vienna final, 3-6, 6-3, 7-5.

And finally, he's now up to 24 career titles, period—tying the most for any man born in 2000 or later (with Alcaraz) as well as the most for any man born in 1990 or later (with Alcaraz and Zverev). Which one of the three will be the first to 25 in 2026?
