In 1943, Theresa played on a WAC softball team from Orlando's Army Air Base which was part of an Orlando, Florida city league.  In addition, Theresa's niece informed us that Theresa was the winning pitcher in a softball fast pitch championship game between Army and Navy in the early 1940's. 

In the AAGPBL, Theresa played for the Kenosha Comets from 1946 to the middle of 1947 when she was traded to the Fort Wayne Daisies.

In 1948, when the AAGPBL switched to overhand pitching, Theresa switched to pitching for the Cardinals of Chicago's National Girls Baseball League, which played by softball rules.
