Jannik Sinner defeated Carlos Alcaraz to win his second consecutive ATP Finals title on Sunday, triumphing without dropping a set in the tournament. In an electric atmosphere in Turin, Sinner used one of his rival's trademark moves — cupping his hand to his ear to rally the crowd — before sealing the victory and falling onto his back in celebration.
The win was particularly significant for Sinner after his defeat to Alcaraz in the US Open final two months ago. He admitted his game had become too predictable and vowed to make changes. In Turin, his reworked serve and added variety proved decisive, notably a forehand lob in the first-set tiebreak and a delicate drop shot to break in the second set.
“There is for sure no better ending for the season,” Sinner said. “It has been an incredible season, so many ups, difficult moments obviously, for various reasons.” His fitness coach Umberto Ferrara, who had been fired and later reinstated after Sinner’s doping case, was in tears in the coaching box.
The match was the latest chapter in a rivalry that has dominated men's tennis in 2025. The pair met in six finals this year, including all four Grand Slams and the ATP Finals. Alcaraz, who won seven of their previous eight meetings, praised his opponent: “You don't have many, but after every loss you come back stronger.” The season saw both players lock out the rest of the field, with Novak Djokovic’s semi-final runs at all four majors overshadowed by their duopoly.
