Wolff will make his U.S. Open debut after tying for fourth in the PGA Championship at TPC Harding Park in his major-championship debut. The Southern California native burst onto the scene last summer as a professional by winning the 3M Open at TPC Twin Cities. This came after a decorated amateur career that saw him win the 2019 NCAA individual title as a sophomore at Oklahoma State, a year after helping the Cowboys capture the team championship. In 2017, Wolff lost in the 36-hole final of the U.S. Junior Amateur Championship at Flint Hills National in suburban Wichita, Kan.
