 Biographical Information
Billy Demars began his playing career in 1943 and was active until 1958, with 9 appearances in 1959-1960. He missed the 1944-1945 seasons due to military service in the US Navy. He was the radio man on a Consolidated PBY "Catalina" search and rescue aircraft.
Demars managed in the Baltimore Orioles system from 1958 to 1968. On June 14, 1966, his Miami Marlins defeated the St. Petersburg Cardinals, 4-3, in a game that required 29 innings and was the longest game played in organized baseball history until then. Demars left managing and the Orioles in 1969, becoming a coach for the Philadelphia Phillies, where he stayed through 1981. He coached for the Montreal Expos from 1982 to 1984, and finally for the Cincinnati Reds from 1985 to 1987. Pete Rose was the link between the three stops, playing with Philadelphia from 1979 until his departure, joining the Expos in 1984 when he was a coach, and then inviting him to serve under him as a coach when he was the Reds' player-manager in 1985.
