Dick Williams managed the Montreal Expos for four-plus seasons on his way to Cooperstown.
Gene Mauch was in charge for seven seasons on his way to winning 1,902 games in his career.
Felipe Alou was the skipper for more than eight seasons.
Yet, the most successful manager of all in franchise history was Jim Fanning.
Fanning managed the Expos into post-season play, bested the Philadelphia Phillies and came within a run of the 1981 World Series when Los Angeles Dodgers outfielder Rick Monday won the decisive game of the National League Championship Series with a ninth-inning homer.
