Jannik Sinner successfully defended his Nitto ATP Finals title on Sunday in Turin, delighting the home crowd. Backed by rousing support from the Italian fans, he overcame Carlos Alcaraz 7-6(4), 7-5….

Alcaraz and Sinner have been the standout performers of the 2025 season, collecting 13 titles combined and sweeping all four Grand Slams. Their dominance made their meeting in Turin a fitting climax on one of the sport’s most prestigious indoor stages.

Sinner has now become the ninth player in history to capture the year-end championship in consecutive seasons. Only a select group of modern greats — including Lleyton Hewitt, Roger Federer, and Novak Djokovic — have accomplished the feat before him.

Under the spotlight and immense pressure, Sinner delivered bold, razor-sharp tennis throughout the night. He fended off a vital set point at 5–6 in the first set and closed out the contest after two hours and 15 minutes, joining a select group of players who have captured multiple ATP Finals trophies on home soil.

How Jannik Sinner beat Carlos Alcaraz in the ATP Finals…

Second seed Jannik Sinner clawed his way back from an early break in the second set, absorbing Alcaraz’s varied shot-making with composed, calculated play. The win extended his remarkable indoor streak to 31 consecutive matches — a run that began after his most recent indoor defeat to Novak Djokovic two years ago. Since that loss, Sinner has piled up multiple indoor titles and played a key role in securing two Davis Cup triumphs for Italy.

Sinner wrapped up the week with an immaculate 5–0 record and departed Turin with the largest prize money haul in the tournament’s history. He didn’t surrender a single set and now boasts the highest winning percentage ever at the ATP Finals, surpassing Ilie Năstase. Over the last two editions, the Italian has won all ten matches he has contested at the year-end championship.

Sinner closed out the week with a flawless 5–0 record and walked away from Turin with the largest prize purse ever awarded at the event. He didn’t lose a single set throughout the tournament and now owns the highest winning percentage in ATP Finals history, overtaking Ilie Năstase. Across the last two editions, the Italian has triumphed in all ten of his matches at the prestigious season-ending tournament.

Alcaraz had already locked up the year-end No. 1 ranking after going undefeated in the group stage, and he carried the confidence of having beaten Sinner in the US Open final. Still, Sinner rose to the occasion on home soil, matching Alcaraz’s energy from the very first games and delivering crowd-lifting winners that sent the Turin arena into a frenzy..
