The Gatlin Brothers Southwest Senior Classic was a golf tournament on the Senior PGA Tour (now PGA Tour Champions) from 1989 to 1990. It was played in Abilene, Texas at the Fairway Oaks Country Club.[1] It replaced the Southwest Golf Classic on the PGA Tour, which had been played from 1981 to 1988 at the same course.
In the inaugural event, George Archer won in a playoff over Orville Moody and Jimmy Powell. Archer had turned 50 just two weeks before and this was his debut Senior PGA Tour event.[2] In the tournament's second and final year, Bruce Crampton won by four strokes over Lee Trevino.[3]
