Munoz will make his fifth U.S. Open start after earning one of the four available berths at a final qualifier in Rockville, Md., advancing from a 4-for-2 playoff after shooting 3-under 139 on the North Course at Woodmont C.C. He registered his lone PGA Tour victory in the 2019 Sanderson Farms Championship. Munoz turned professional in 2015 after a successful college career at North Texas University, where he won two tournaments in his senior season (2015), including the Conference USA title. He then quickly won two tournaments on the PGA Tour Latinoamerica's Developmental Series, which earned him exempt status on PGA Tour Latinoamerica. Playing on a sponsor's exemption in the 2016 Club Colombia Championship, an event on the Web.com Tour (now Korn Ferry Tour), Munoz came away victorious and eventually finished 22nd on that circuit's money list to earn PGA Tour playing privileges for the 2016-17 season.
