The event is the third of four tournaments that determine 25 PGA Tour cards. The series features the top 75 players from the Web.com regular-season money list, Nos. 126-200 in the PGA Tour's FedEx Cup standings and non-members with enough money to place in the top 200 in the FedEx Cup had they been eligible. Lindheim, a PGA Tour rookie this season, finished 197th in the FedEx Cup.
Atkins has already earned a PGA Tour card by finishing in the top 25 on the regular-season Web.com money list. Those players are competing for tour priority, with regular-season earnings counting in their totals.
