Born in Mobile, Alabama, Adair was a skipper in the Braves organization (he managed farm clubs for all three cities the Braves played in), as well as the Detroit Tigers, San Diego Padres, Montreal Expos, and the Chicago White Sox organizations. Adair was a big scout for the Philadelphia Phillies. He compiled a 1,611-1,305 (.552) record in the minors, but his managing career in the Major Leagues was limited to ten games with the 1970 White Sox. Skipper Don Gutteridge was fired September 3 with 26 games left in the season and Adair was named interim manager. Adair then compiled a 4-6 (.400) record before Chuck Tanner took over as manager on September 14, 1970. The White Sox lost 106 games that season.
Adair also was a Major League coach for the Braves (1962; 1966), White Sox (1970) and Expos (1976).
