Watertown Expos
The Watertown Expos were a short-lived South Dakota farm club of the Montreal Expos that competed in the Class A Northern League during the summers of 1970 and 1971. By this time, the venerable Northern League was on its last legs. The circuit fielded just four ball clubs during the summer of 1971. Montreal pulled the plug on its Watertown operation in November 1971 and the rest of the Northern League gave up the ghost a few months later. Professional baseball has never returned to Watertown, South Dakota since the Expos departure in 1971.
