Marie Mansfield (later Kelley, November 4, 1931 – January 28, 2024) was an American pitcher who played from 1950 through 1954 in the All-American Girls Professional Baseball League.
Guided by her manager Bill Allington, she showed promise on the pitcher's mound with her fluid overhand delivery, which the league had converted in 1946.
[2] In 1951, Mansfield teamed up with Rose Gacioch and Helen Fox to give Rockford a strong one-two-three punch pitching combination in the eight-team circuit.
She collected a 16–8 record and a 2.85 earned run average in 30 games, ending fifth in wins, eighth in innings pitched (202), and third in strikeouts (121) behind Jean Faut of the South Bend Blue Sox (135) and Margaret Holgerson of the Grand Rapids Chicks (123).
In the first round of the best-of-three series, Rockford swept the favored Chicks backed by victories from Fox and Mansfield and the bats of Eleanor Callow and Dorothy Kamenshek.
