Sigg will make his second consecutive U.S. Open start after shooting 9-under 135 in the Atlanta final qualifier conducted at the Piedmont Driving Club. Sigg picked up his first Korn Ferry Tour victory on March 21 at the Visit Knoxville Open, carding a final-round 66. It was his eighth top 10 of the wrap-around 2020-21 season, and catapulted him to No. 2 points standings (he currently is third). Last year, he was the runner-up to Brandon Wu in the Korn Ferry Tour Championship presented by United Leasing and Finance. Sigg graduated from the University of Georgia in 2017, where he served as team captain during his senior season and earned third-team All-America honors. Prior to 2020, he spent two seasons on the Mackenzie Tour-Canada, earning his Korn Ferry Tour card for 2020 by finishing ninth on the circuit's Order of Merit.
