World No. 2 Jannik Sinner defeated world No. 1 Carlos Alcaraz 7-6(4) 7-5 on Sunday in Turin to defend his ATP Finals crown, closing his season with a flawless run defined by clinical serving. Throughout the game, or rather this season, his consistency under pressure proved decisive. His victory marks his 24th singles title and extends his indoor winning streak to 31 matches.

Sinner also remains perfect in sets at the ATP Finals since 2023, becoming the first player since the tournament’s inception in 1970 to win multiple and consecutive editions without conceding a set. The achievement places him among rare company, as he becomes only the fourth youngest to win consecutive ATP Finals, older than only Lleyton Hewitt, Ivan Lendl and Roger Federer.

Sinner’s Historic Defence and Absolute Dominance

The match carried its drama. A big smile from Alcaraz appeared after he fired his 27th winner past Sinner, but the dynamic shifted quickly. His movement was compromised by the leg issue he received treatment for earlier, even as he struck winner number 28. At deuce, a missed stooping volley gave Sinner match point.

The Italian secured the title as Alcaraz sent a backhand wide, ending Sinner’s season on a 15-match win streak. Sinner also joins the elite company of Novak Djokovic, Roger Federer, Lleyton Hewitt, Pete Sampras, John McEnroe and Bjorn Borg as the ninth man to defend his ATP Finals title.

In a broader context, this was their 16th meeting, with Alcaraz still leading 10-6, yet the Turin stage now feels distinctly Sinner’s. He finishes on a 15-match winning streak and a perfect fortnight at the Finals. Alcaraz leaves with bruises and regrets, but also with another tight chapter in a rivalry that keeps narrowing. Sinner, for now, owns the last word of 2025, but the future still looks like a shared conversation.

The 24th Jannik Sinner trophy lift at 24 years old.

My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
