It only made sense that Jannik Sinner's breakout year ended with a celebration in Turin, Italy. The Italian superstar won his first two Grand Slams this year and completed the season by winning the ATP Finals title. He is the first Italian to win the year-end tournament.

Top-ranked Jannik Sinner added another big title to his tremendous year by beating U.S. Open runner-up Taylor Fritz 6-4, 6-4 for the ATP Finals trophy before his home fans and before a final verdict is reached in his doping case.
