Sinner defeats Alcaraz to defend ATP Finals title, intensifying the “new king” rivalry

1. Event outcome: Sinner beats Alcaraz, successfully defends ATP Finals crown in season finale

On November 16, 2025, the ATP Finals wrapped up at Turin’s Pala Alpitour, with Italy’s Jannik Sinner defeating Carlos Alcaraz in the final to successfully defend his championship, marking a perfect end to the season. This marks Sinner’s second ATP Finals title in his career. Having already won the Paris Rolex Masters earlier, combined with his Australian Open and Wimbledon titles at the start of the year, Sinner captured four major titles in 2025, showcasing remarkable competitive consistency.

2. Data comparison: Rivalry between the two stars highlights, Sinner narrows gap with impressive efficiency

1. Major titles head-to-head

The two have claimed all four Grand Slam titles and the ATP Finals in the 2025 season, establishing a “duo rivalry” as the new dynamic in tennis. The breakdown of their title counts is as follows:

2. Winning efficiency ranks among the best in history

Sinner wins a major title every 5.8 tournaments on average in his career, surpassing Andre Agassi’s rate of 6.1 tournaments per title, placing him sixth on the all-time list.

He trails only:

Novak Djokovic (3.3 tournaments per title).

Rafael Nadal (3.5 tournaments per title).

Carlos Alcaraz (3.9 tournaments per title).

Roger Federer (4.4 tournaments per title).

Pete Sampras (4.9 tournaments per title).

Additionally, the ATP Finals is a key venue where Sinner has closed the gap; he has competed four times and won twice, while Alcaraz has yet to claim this prestigious title.

3. Historical significance: Breaking multiple records, entering legendary ranks

1. Back-to-back ATP Finals titles:Sinner became the ninth man to achieve consecutive ATP Finals championships and the fourth player this century to do so.

Lleyton Hewitt (2001-2002).

Roger Federer (2003-2004, 2006-2007, 2010-2011).

Novak Djokovic (2012-2015, 2022-2023).

2. Multiple home soil titles:He is the third player in history to win the ATP Finals multiple times on home soil, following American John McEnroe (three titles in New York) and German Boris Becker (two titles in Frankfurt).

3. Reshaping the tennis landscape:The rivalry between Sinner and Alcaraz continues to intensify, with their “new king” battle not only ushering in a new era of competition in tennis but also fueling fans’ anticipation for every future encounter between them.

Sinner still has room for growth this year, having missed four ATP Masters 1000 events (Indian Wells, Miami, Monte Carlo, Madrid) due to a three-month suspension. Furthermore, Sinner’s form has been notably more consistent.

The 2026 season could see their rivalry reach a boiling point. Currently, Sinner’s team is making detailed tactical adjustments, seemingly following Djokovic’s training approach.

No similar news has emerged from Alcaraz’s camp yet. However, Alcaraz’s serve continues to improve steadily.

Looking forward to 2026…
