Career
He played in Major League Baseball as a third baseman for two seasons. Demeter played for the Detroit Tigers in 1959. The trade turned out to be one of the most lop-sided trades in Major League Baseball history, as Demeter played only four games for the Indians before being returned to the minor leagues, from which he never returned.
Demeter was a fixture of the Rochester Red Wings teams of the midto late 1960s, hitting 272 minor league home runs in his long career, and has been inducted into both the Rochester Red Wings Hall of Fame, in 1990, and the International League Hall of Fame, in 2009.
He served one year (in 1985) as a coach with the MLB Pittsburgh Pirates, working at first base through June 13, and then as bench coach, and also managed for nine seasons in the Pirates" farm system, at the helm of the Sherbrooke Pirates (1972), Salem Pirates (1973. 1976-1977), Charleston Charlies (1974-1975), Shreveport Captains (1978), and Buffalo Bisons (1979-1980).
He also was a roving instructor and scout for the Bucs. Demeter"s grandson, Derek Dietrich, is a professional baseball player.
