Jannik Sinner beats Carlos Alcaraz to retain ATP Finals title before home fans in Italy

The final installment of the "Sincaraz" rivalry for 2025 went to Jannik Sinner.

The second-ranked Sinner beat the top-ranked Carlos Alcaraz 7-6 (4), 7-5 for the ATP Finals trophy on Sunday in the sixth meeting this year between the two players who are dominating men's tennis.

Sinner defended the title before his home Italian fans in Turin for only his second victory over Alcaraz this year after also beating the Spaniard in the Wimbledon final.

"It was an incredible season," Sinner said. "To finish it this way, before my Italian fans, is very special for me."

Alcaraz had already secured the year-ending No. 1 ranking and was contesting his first final at the event for the year's top eight players.

Alcaraz still leads his career meetings with Sinner 10-6.

Sinner and Alcaraz have met in the last three Grand Slam finals. Alcaraz beat Sinner in a fifth-set tiebreaker to win the French Open; Sinner gained a measure of revenge at Wimbledon; then Alcaraz again came out on top at the U.S. Open.

They also clashed this year in the Italian Open final (won by Alcaraz) and the Cincinnati Open final (won by Alcaraz when Sinner retired due to illness).

Sinner also won the Australian Open — beating Alexander Zverev in the final — so he and Alcaraz each won two majors this year.

In all, Alcaraz has won six majors and Sinner has won four.

The first time was so nice, he had to do it twice
