This Day in Golf History--May 18

On this date in 1964, Arnold Palmer won his 44th PGA Tour Event at the Oklahoma City Open. Arnie took on rain, a condensed schedule and government testing of sonic booms and still won. The Feds were testing the effects of sonic booms—seriously—and OKC was the testing ground. Maybe that’s why the heavens let loose and caused Thursday and Friday to be unplayable due to rain, pushing everything back to a 36-hole finale on Monday. Palmer won first prize of $5,800, at Quail Creek Country Club (72, 7,042).
