• World No1 wins final 6-4, 6-4 in front of home fans
• Wada cleared him of wrongdoing after positive drug tests

Jannik Sinner added another big title to his tremendous year, beating the US Open runner-up Taylor Fritz 6-4, 6-4 for the ATP Finals trophy in front of his home fans in Turin – and before a final verdict is reached in his doping case.

Sinner won his first two grand slam titles at the Australian Open and US Open this year and had already clinched the year-end No 1 ranking. He also tested positive in two separate drug tests in March and a decision to clear him of wrongdoing was appealed against by the World Anti-Doping Agency in September. A final ruling is expected from the court of arbitration for sport early next year.
