Jannik Sinner delivered a powerful closing statement to his spectacular 2025 season with a straight-sets triumph over Carlos Alcaraz in the ATP Finals championship match in Turin. In front of an electric home crowd and on the indoor hard courts where he has become nearly unbeatable, Sinner prevailed 7-6 (4), 7-5 to successfully defend his year-end title.
The victory was especially significant given the dynamic between the two rivals this season. While Sinner dominated almost everyone else on tour, posting an extraordinary 85-2 record against the rest of the field since last August, he had struggled against Alcaraz, losing seven of their eight meetings this year. This time, however, the Italian seized the moment, playing with conviction and precision to ensure he ended the year on equal footing with the Spaniard.
Sinner wraps up the season with six titles, a stunning 58-6 record, and three of the five most prestigious trophies of the year. His dominance on indoor hard courts is now unquestioned; the win in Turin extended his unbeaten streak on the surface to 31 matches, a run that began with his pivotal role in Italy’s Davis Cup triumph in 2023. At only 24, he becomes the youngest man since 2004 to defend the ATP Finals title and just the second to do so without dropping a set in consecutive years.
The match itself was a display of ferocious, first-strike tennis from both players. Each came out serving aggressively and hitting with full force as they battled for control. A brief medical interruption in the stands did nothing to slow the intensity. Alcaraz appeared poised to edge ahead late in the opening set, creating a set point at 6-5, but Sinner responded with a fearless 116mph second serve before closing out the tie-break with two superb lobs.
Alcaraz battled tightness in his right hamstring from midway through the first set and played with his leg heavily taped in the second. Though he managed an early break, his movement lacked its usual explosiveness. Sinner seized on this vulnerability, displaying improved net play, better variation, and a refined service technique that had been honed after his disappointment at the US Open.
Fueled by the passionate Italian crowd, Sinner elevated his energy and emotion, celebrating big moments and refusing to let the opportunity slip. He closed out the match with authority, securing not just another title but a season-defining victory that cements his status as one of the world’s elite heading into 2026.
