Italian Sinner brought the house down by winning the championship match tennis fans wanted to see, adding the prestigious year-ending tournament to the Australian Open and a landmark triumph at Wimbledon this season.

"It's (an) amazing season... This year making four Grand Slam finals, coming here, winning here, having this big streak in end of the year, it's amazing," Sinner told reporters.

The 24-year-old also bounced back from a three-month ban which chopped out a large chunk of his season despite the World Anti-Doping Agency accepting that the Italian was accidentally contaminated with banned substance clostebol last year.

"It has been a really long week... it was a brilliant atmosphere here, it was almost like being at a football match," said Sinner on court to loud cheers.

"I'm really happy to have given something positive to all of you."
