Jannik Sinner defeats Carlos Alcaraz in straight sets to retain ATP Finals crown in Turin

Jannik Sinner closed his season in perfect style on Sunday night, defeating Carlos Alcaraz in straight sets to retain his ATP Tour Finals title in Turin. The Italian edged a tense first set in a tiebreak before rallying from a break down in the second to seal a 7-6(4), 7-5 victory in front of a packed home crowd.

It was the sixth final between the two players in a remarkable season that has reshaped the top of men’s tennis. Although Sinner arrived with just one win over the Spaniard in championship matches this year, he delivered his most composed performance when it mattered most. The win adds to his Wimbledon triumph and further strengthens a rivalry that has quickly become the defining duel of the sport.

A Tight Match From the Start

Alcaraz came into the match nursing a hamstring issue but still found pockets of brilliance. He created a set point late in the opener yet couldn’t convert, and Sinner punished the missed opportunity by taking control of the tiebreak.

The second set began with Alcaraz breaking immediately, but Sinner refused to panic. Using his serve as a foundation, eight aces and dominant first-serve numbers, the Italian won six of the last eight games to turn the match around. He saved two of three break points while applying pressure on crucial return moments, eventually breaking at 5-5 before serving out the match with confidence.

The numbers reflected just how narrow the margins were: Sinner won 78 total points to Alcaraz’s 72, while winners and unforced errors were nearly identical on both sides. Even so, Sinner’s ability to rise in the biggest moments was the difference.

A season split between Tennis’ New Titans

The scoreboard might favour Sinner in Turin, but the broader picture shows how evenly matched the pair have been all year. Their achievements across 2025 underline a two-man race:

• Australian Open: Sinner
• French Open: Alcaraz
• Wimbledon: Sinner
• US Open: Alcaraz
• ATP Finals: Sinner
• Year-End No. 1: Alcaraz

Only the Australian Open final didn’t feature both players, highlighting how far they’ve pulled ahead of the pack.

With this win, Sinner becomes the first player in ATP Finals history to win back-to-back titles without losing a set. At 24, he joins elite company, only Lleyton Hewitt, Ivan Lendl and Roger Federer achieved consecutive titles at a younger age. His clean, fearless shot-making and tactical discipline continue to evolve, and Turin felt like another step toward a long-term era at the top.

Mutual Respect on Display

The post-match ceremony showcased the warmth between the two competitors. Sinner took time to praise Alcaraz’s season and resilience, acknowledging how much their rivalry pushes him to improve. Alcaraz, still smiling despite the defeat, responded with competitive fire, promising he’ll be ready for more finals next year.

Alcaraz now turns his attention to the Davis Cup Finals, though his participation will depend on how his hamstring responds. Sinner, meanwhile, has opted to close his season here, choosing rest over a late push for Italy.

A Rivalry That Tennis Needed

As the year ends, it’s hard to choose which season was better. Alcaraz finishes as world No. 1 with two major titles; Sinner claims two majors of his own plus the ATP Finals crown. What’s certain is that their rivalry has re-energised men’s tennis. Every meeting feels like a final, and every final feels like the start of something bigger.

In Turin, Sinner had the final word, but this is a chapter, not an ending.
