Jannik Sinner says it "means so much" to win the US Open after a "very difficult" period following the controversy over his positive tests for a banned substance.
The world number one stormed past American Taylor Fritz in Sunday's final to claim his second Grand Slam of the year.
It was revealed six days before the tournament started that Sinner had been cleared of any wrongdoing after twice testing positive for low levels of a metabolite of clostebol - a steroid that can be used to build muscle mass - in March.
