Theresa Kobuszewski

Who was Theresa Kobuszewski?

Theresa Kobuszewski [Koby or Tracy] was a pitcher who played from 1946 through 1947 in the All-American Girls Professional Baseball League.

Born in Wyandotte, Michigan, Theresa Kobuszewski was a feary and respected underhand pitcher for fifteen years before joining the All-American Girls Professional Baseball League as a 26-year-old rookie in 1946.

Kobuszewski played for the Keller Girls softball team at Mack Park, which was the original home field of Detroit's Negro National League franchise Detroit Stars, and then joined the Women's Army Corps in 1942. In the process, she was the winning pitcher in the championship game between the Army and Navy teams. Her softball experience made her an attractive selection for AAGPBL scouts. Unfortunately, she could not adjust when the league switched for a strictly overhand pitching in 1948.

Kobuszewski entered the AAGPBL in 1946 with the Kenosha Comets, playing for them one and a half years before joining the Fort Wayne Daisies in the 1947 midseason. In her rookie season she finished with a 3–9 record and a 2.71 earned run average in 123 innings of work, spanning 21 games. She improved to a 11–15 mark and a 2.42 ERA in 1947, striking out 47 batters in 208 innings while playing with both Kenosha and Fort Wayne.
