The United States Disc Golf Championship is a disc golf tournament held at the Winthrop Gold Course, on the campus of Winthrop University in Rock Hill, South Carolina. The professional event was held annually from 1999 to 2010, before moving to a biennial schedule. Along with the PDGA World Championships, it is one of the most prestigious major tournaments in disc golf. The primary sponsor for the event over the past decade has been Innova, a disc manufacturer. Ken Climo currently holds a record five US Disc Golf Championships. He is followed by Barry Schultz who has recorded three titles. The most recent champion is Will Schusterick with the first back to back wins since Ken Climo's 1999-2000 wins. Schusterick is looking to set a new record at the 2013 US Open with the first three-peat in USDGC history.
