F-19: Winners of PGA Tour Champions co-sanctioned events between the 2025 U.S. Senior Open and the initiation of the 2026 championship

Gainey will make his U.S. Senior Open debut after registering his first PGA Tour Champions victory at the Constellation Furyk & Friends as a Monday qualifier. The Darlington,  S.C., native registered one PGA Tour victory at the 2012 McGladrey Classic. He also produced three Korn Ferry Tour victories, the last coming in the 2020 Bahamas Great Exuma Classic. Gainey earned the nickname "Two Gloves" because he wears gloves on both of his hands. Gainey attended Central Carolina Technical College, graduating in 1999. He briefly worked on an assembly line, wrapping insulation around water heaters for A.O. Smith Corporation before his professional golf career took off. He also appeared on Golf Channel's Big Break IV and returned for Big Break VII, a reunion event held at The Reunion Resort in Florida.
