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.

World No. 1 Jannik Sinner ended a spectacular season in style on Sunday, winning his career-first Nitto ATP Finals in his native Italy. Sinner needed just 85 minutes to defeat Taylor Fritz 6-4, 6-4 for his 70th match win and eighth tournament victory of the season.

A final verdict in the doping case involving top-ranked Jannik Sinner likely won’t come until early next year.

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.

Jannik Sinner tested positive twice for an anabolic agent in March, but avoided a ban after an independent tribunal accepted his defence.
