Several different Minor League Baseball teams have been located in the city of Waterbury, Connecticut since 1884.
These teams went by several different nicknames during this period, including the Brassmen, Brass City, Indians, Pirates, Rough Riders, Authors, Invisibles, Finnegans, Champs and Spuds.
From 1966-1986 (with the exception of 1972), the Waterbury team played in the Eastern League as an affiliate of the Giants, Cleveland Indians, Pittsburgh Pirates, Los Angeles Dodgers, Oakland Athletics, Cincinnati Reds and California Angels.
However, midway through the season, flooding in Elmira, New York made the home ballpark of the Elmira Pioneers unusable, forcing them to play their "home games" in the second half of the 1972 season in Waterbury.
The Independent Northeast League chose to place a team in Waterbury in 1997 as the Waterbury Spirit, but they folded after the 2000 season, only to be resurrected in 2003 under a new owner, relocating to Lynn, Massachusetts and becoming the North Shore Spirit.
