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.
