Wolff had never played a major championship until the 2020 PGA Championship, but he finished joint fourth and six weeks later was runner-up to Bryson DeChambeau in the U.S. Open.
He held the 54-hole lead there as he tried to become the first debutant winner since amateur Francis Ouimet in 1913 and, at 21, the youngest major champion since Tiger Woods at the 1997 Masters.
His runner-up finish took him into the world’s top 20 for the first time, only 14 months after he stood 1,659th, and on his next start three weeks later he was in a three-way play-off for the Shriners Hospitals for Children Open, but Martin Laird lifted the title at the second extra hole.
Just a month after turning professional in 2019 Wolff achieved his maiden PGA Tour success in the 3M Open, where his closing eagle for a round of 65 took him one ahead of DeChambeau and Collin Morikawa.
He was playing on a sponsor’s invitation and joined Woods and Ben Crenshaw as the only players to win the NCAA title and a PGA Tour event in the same calendar year.
