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.

Jannik Sinner cemented his status as the best player in men’s tennis by winning a first ATP Finals title in front of his home fans in Turin. The Italian has got better and better as the season has gone on, despite the doping case hanging over his head that could still lead to a suspension.

There "could have been better communication" in explaining the rules involved in Jannik Sinner's doping case, but no double standard was applied, ATP Tour chairman Andrea Gaudenzi acknowledged.
