Jannik Sinner defeated Carlos Alcaraz on Sunday in Turin to win the ATP Finals, a result that capped a season in which the two leading men on the tour have defined the sport’s narrative. Their latest pulsating contest, this time with the season-ending trophy on the line, felt an inevitable conclusion to a year that belonged to both.
For Sinner, the victory carried particular weight. The mild-mannered Italian collapsed onto his back after championship point, a release that reflected the importance of defending the prestigious title in front of passionate home support. The 24-year-old, who won the Australian Open and Wimbledon but also served a three month ban after failing two doping tests, described the 7-6 (7-4) 7-5 win as meaningful. “I am very happy. It was a tough match, but it means a lot to me ending the season like this,” he said.
The result also kept Alcaraz in check. Although the pair split the four Grand Slam titles this season, there had been a sense that the Spaniard held a slight edge. Alcaraz had already secured the year-end number one ranking and his commanding US Open final win had extended his head-to-head lead over Sinner to 10-5. After that defeat, Sinner admitted he needed to leave his comfort zone to test Alcaraz, then proved his resilience once again in Turin.
Alcaraz acknowledged as much. “After every loss, you do not have many, you come back stronger,” he said during his runners-up speech, smiling with the infectious ease that has made him a global favourite. The intent behind his words, though, was unmistakable. He and his team, led by Juan Carlos Ferrero, will be analysing the margins when they return to work.
That constant search for improvement is what makes this rivalry compelling. As former British number one Laura Robson said on Sky Sports, “They bring the best out in each other, they know they have to push each other and improve constantly to outdo one another.” Tim Henman called their level “frightening” for the rest of the tour, pointing to the widening gap.
Since the US Open, Sinner has worked on serving more aggressively and adding variety. The adjustments were clear. Facing a set point at 6-5 on his serve in the opener, he fired a 117mph second serve to Alcaraz’s backhand, then followed with two unreturnable first serves to force a tie break which he controlled. In the second set, with Alcaraz hindered by a strapped hamstring, Sinner mixed in more drop shots, including one that saved a break point in the seventh game. A final break sealed the match and completed an undefeated run in Turin without dropping a set.
“You are definitely a player I look up to,” Sinner told Alcaraz after extending his indoor winning streak to 31 matches. “You give me a lot of motivation, I need this, in every practice session with a big purpose. I hope to see you again next year with, hopefully, great battles ahead of us.”
The tickertape had barely fallen before thoughts turned to 2026. The warmth between the two rivals is genuine, yet so is the hunger to face each other again. Fans are already anticipating their next meeting, likely months away. A rematch in the Australian Open final would be the dream scenario, with Sinner defending his Melbourne title and Alcaraz aiming to become the youngest man to complete the career Grand Slam.
On the evidence of this season and their latest encounter, few would bet against it.
