Jannik Sinner defeated Carlos Alcaraz to win his second consecutive ATP Finals title on Sunday.
Sinner, who saved a set point in the first set, eventually defeated his great rival 7-6, 7-5 in front of an ecstatic Italian crowd in Turin.
The Italian has now won 31 consecutive indoor hard-court matches and has become the first player in ATP Finals history to win back-to-back tournaments without dropping a set.
Sinner praised Alcaraz’s return game immediately after the match, and Alcaraz, who will end the year as world number one, was as gracious as ever during his post-match speech.
This was a historic victory for Sinner, one that will live long in the memory.
Jannik Sinner is the youngest player to defend his ATP Finals title since Roger Federer in 2004
Roger Federer was 22 years old when he won his first ATP Finals in 2003.
The Swiss Maestro, who defeated Andre Agassi in the final, repeated the feat in 2004 while aged 23.
In 2004, 23-year-old Federer defeated Lleyton Hewitt in the final: 6-3, 6-2.
Almost 20 years later, Jannik Sinner has rivalled Federer, becoming the youngest player to defend his ATP Finals title since the Swiss Maestro defeated Hewitt in 2004.
After winning his second ATP Finals title, Sinner will be eyeing up Federer’s total of six – a tally only surpassed by Novak Djokovic, who has won the tournament seven times.
Could Jannik Sinner three-peat in 2026?
Jannik Sinner has handed himself the opportunity to achieve something remarkable in 2026: winning three consecutive ATP Finals titles.
The last player to do so was Novak Djokovic, who won four consecutive titles between 2012 and 2015.
If Sinner does win three consecutive titles in Turin, he would become the fourth player in ATP Finals history to do so.
Alongside Djokovic, Ilie Nastase and Ivan Lendl have also achieved the feat.
Nastase won the title from 1971 to 1973, while Lendl did so between 1985 and 1987.
Remarkably, Lendl reached the final of the tournament on nine consecutive occasions between 1980 and 1988. This record remains unbroken to this day.
