Theresa Kobuszewski also went by Tracy.  She was a well-known fast-pitch softball player in Southeast Michigan for several years throughout grade school.  Eventually, she made her way to the Detroit area pitching for a Team known as the Keller Girls.  In 1942, she joined the Women's Army Air Corps (WAC).  She excelled in softball while serving her country, too. While stationed in Orlando, Florida, in 1943, she was the winning pitcher in the Orlando Girls City Fast-pitch Softball Championship Game as a member of the Army Air Forces School of Applied Tactics (AAFSAT) of the WAC.  She transferred to a position in the United Kingdom in 1944.  The following year, she helped win the European Theater of Operations (ETO) basketball championship with the WAC’s team which defeated the United Kingdom team 50-43.  Moreover, she played as a member of the Air Force Service Command WAC team that lost in the Eighth Air Force Championship Volleyball Final to the Headquarter’s team.  

After being honorably discharged in December of 1945, she joined the AAGPBL in 1946. 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.  She was a decent hitting pitcher in the professional softball league with a .235 average in 81 at bats.

Theresa returned to the Air Force in 1951 and served until she retired in 1975. During her second stay in the military, she continued playing and winning several softball championships.
