The Italian won 6-3 6-4 7-5 against the home favourite.
The world number one came into the tournament under a cloud following his anti-doping scandal, where he escaped a ban despite two positive tests in March.
Fritz, backed by a partisan crowd on Arthur Ashe, was hoping to become the first American to win the men’s US Open title since Andy Roddick in 2003. An independent tribunal accepted Sinner’s explanation that clostebol, an anabolic agent that can aid muscle growth, had accidentally entered his system via a product one of his team had used to treat a small wound.
He was aided by the early exits of Carlos Alcaraz and Novak Djokovic but did what he needed to do throughout a tournament he grew into. A couple of wayward shots handed Sinner the set points, which he took with a speared backhand down the line.
