The AAGPBL grew to an all-time peak of ten teams in that season, representing Eastern and Western zones, just in the first year the circuit shifted to strictly overhand pitching.

[1][2] The Chicago Colleens and the Springfield Sallies were added to the previous roster that included the Kenosha Comets, Fort Wayne Daisies, Grand Rapids Chicks, Muskegon Lassies, Peoria Redwings, Racine Belles, Rockford Peaches and South Bend Blue Sox.

In the first round, Grand Rapids, Fort Wayne, Racine and Rockford swept South Bend, Muskegon, Peoria and Kenosha, respectively.

Helen Nicol was credited with four of the 10 playoff wins of Rockford, including two in the finals, while Lois Florreich and Margaret Holgerson took three a piece.

Another highlight came in the first round, when South Bend's Jean Faut outdueled Haylett of Grand Rapids, 3–2, in 20 innings, in what would be the longest game in AAGPBL playoff history.
