World No. 1 Jannik Sinner defeated American Taylor Fritz 6-4, 6-4 to win the ATP Finals in Turin, Italy, on Sunday, claiming the trophy for the first time on home soil.

Jannik Sinner won the ATP Finals against Taylor Fritz in front of a home crowd. For a man who is still under a doping cloud, Sinner is hitting the cleanest winners.

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.
