It’s supposed to be the tournament where the year’s top eight players battle it out for one last prestigious trophy.

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 defeated Taylor Fritz 6-4, 6-4 to capture his maiden ATP Finals title in front of a home crowd in Turin, Italy. Sinner’s triumph was his 26th win in his last 27 matches, capping off a remarkable year that included the Australian Open and US Open titles.

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.
