ATP Finals: Jannik Sinner beats Carlos Alcaraz to defend title in Turin

Jannik Sinner signed off his 2025 season in style by overcoming world number one Carlos Alcaraz in two tight sets to defend his ATP Finals crown in Turin.

For the second consecutive year, the Italian captured the title without dropping a set throughout the tournament, winning 7-6 (7-4) 7-5 in the final, and is now unbeaten in 31 consecutive matches on indoor hard courts.

It is Sinner’s second victory in six finals against Spaniard Alcaraz this season and closes the gap in their head-to-head record to 10-6.

Although he missed out on the year-end number one ranking, this triumph caps off a successful year on court for Sinner, who won two Grand Slam titles and reached all four major finals.

He missed three months of the season to serve a doping ban but still collected six titles – the second-best haul of his career – after reaching the final in 10 of the 12 tournaments he entered.

This latest win extends his prolific record at the end-of-season showpiece, where he has not lost a match since being defeated by Novak Djokovic in the 2023 final.

Sinner becomes just the fourth player to successfully retain the men’s singles title this century, joining Lleyton Hewitt, Roger Federer and Djokovic.

After the first 11 games came and went without a break point, Sinner was forced to save set point with a huge second serve.

He then dominated the tie-break, capitalising on a run of backhand errors from Alcaraz and executing a couple of pinpoint lobs, to seal the first set.

His usually reliable serve faltered in the opening game of the second, with a pair of untimely double faults gifting Alcaraz, sporting a bandaged right thigh after receiving treatment earlier in the match, an early break.

However, Sinner hit back with a break of his own in the sixth game before saving a break point in the seventh to keep the set on serve, whipping the crowd into a frenzy with each point he won.

With Alcaraz serving to stay in the match in the 12th game, Sinner forced deuce with a down-the-line backhand before dropping to the floor as consecutive errors from his opponent confirmed the Italian’s successful title defence.
