Jannik Sinner has ended the tennis season as he started it, the Australian Open champion concluding his astonishing, drama-filled year by downing his greatest rival and world No.1 Carlos Alcaraz to successfully defend his ATP Finals crown.
The latest battle between the world's two dominant men's players had all the feel of another major championship final, but in front of his own adoring fans in Turin, the Italian world No.2 won the day with his glorious Sunday best 7-6 (7-4) 7-5.
To cap a season in which they shared the four grand slam crowns, the end-of-term decider between the pair was another spectacular, close-fought duel, but though Alcaraz has wrestled back the top ranking, it's Sinner who showed again why he's the king of the indoor arenas.
