A founding member, the team represented South Bend, Indiana, and played their home games at Bendix Field (1943–1945) and Playland Park (1946–1954).
The Blue Sox were one of two teams to play in every AAGPBL season without relocating, the other being the Rockford Peaches.
Together, pitchers Margaret Berger and Doris Barr threw 79 of the 91 games played by the Sox.
The South Bend club went on to win their next four playoffs in claiming back-to-back championship titles in 1951 and 1952.
Apart from the aforementioned Barr and Berger, the South Bend included talented players as Mary Baker (C), Jean Faut (P) Betsy Jochum (OF/1B), Elizabeth Mahon (OF), Betty Whiting (IF), and Dottie Schroeder (SS), who played with four teams to become the only girl to play through the 12 years of existence of the circuit.
