Novak Djokovic defeated Yannick Sinner of Italy 6-3, 6-3 to win his record-setting sixth ATP Finals championship in Turin.
Djokovic's victory over Sinner in Italy's final tournament of the season tied him for first place in the world with the recently retiring Roger Federer.
At the end of a year in which he won three Grand Slams—bringing his tally to 24—and his 40th Masters 1000 title, Djokovic reached the finals.
Djokovic seized charge of the match early on, broke Syner in the fourth game at the first opportunity and then served out the first set with ease. Early in the second set, he suffered another break of serve.
Unfortunately for Sinner, he was no match for Djokovic and lost the match via double fault. Novak Djokovic ended his remarkable season - which also saw him reach the Wimbledon final - with yet another record by taking on two of the top young players.
After his remarkable victory over Djokovic in the group stage, Sinner appeared to be on the verge of being the first Italian to win a finals crown. Like Carlos Alcaraz on Saturday's semi-final, the 22-year-old just couldn't defeat Djokovic, who was in top form when it mattered most.
It's a measure to how far Sinner has gone in the past year, though, that he held Djokovic's fate in his hands at the conclusion of the group round, when defeat by Holger Rüne would have sent the Serb home early.
Even yet, Sinner has all the makings of a serious Grand Slam contender next year.
