In 1941, Pratt got a job teaching in Quincy. The All-American Girls Professional Baseball League formed at around that time, and after the school year ended in 1943, Pratt joined the league as a member of the Rockford Peaches.[2] She played in 24 games during her first season, going 5–11 on the mound and batting .235.[1]
The following season, Pratt was transferred to the Kenosha Comets team. She immediately had her best season, winning 21 games and pitching a no-hitter, while leading the Comets to the league championship series.[2][3][4] During this time, Pratt "was very effective using a controlled slingshot or windmill windup to get hitters out".[2]
Pratt slumped in 1945, going just 1–16. She won just 1 more game in 1946 and 1947 before retiring from professional baseball.[1]
Later life
Pratt continued to teach physical education classes in Quincy until 1986, and she also coached the school softball, basketball, soccer, and tennis teams.[2] She won 10 softball championships in the state of Massachusetts.[2]
Pratt has been inducted into the New England Sports Museum, Boston University Hall of Fame, and Boston Garden Hall of Fame.[2]
Pratt died at the John Scott nursing home in Braintree, Massachusetts, on May 6, 2020, aged 101.[5][6][7]
