Chicago Colleens
The team was based Chicago, Illinois and played their home games at Shewbridge Field.
The Colleens joined the strong Eastern Division in the 1948 season and were managed by former Major League player Dave Bancroft.
The team was the worst in the league, getting roughed up as a last-place expansion club with a 47–76 record, ending twenty nine and a half games out of the first place spot in the division.
From 1949 through 1950, the Colleens and the Sallies became rookie development teams that played exclusively exhibition games.
The team's 1948 games were broadcast regularly on television station WBKB in Chicago.
