The Racine Belles franchise was moved to Battle Creek, Michigan, while the Chicago Colleens and Springfield Sallies traveling teams were disbanded.

Betty Foss of Fort Wayne led all hitters for the second year in a row with a .368 batting average, breaking her own single-season record of .346 set in her rookie season.

The Player of the Year Award was given to South Bend pitcher Jean Faut, who posted a 15–7 record with a 1.33 ERA and a league-leading 135 strikeouts, including a perfect game against Rockford on July 21 of that season.

In the other series, Rockford's Helen Nicol gave up six hits and shut out Grand Rapids in the first contest, while Marie Mansfield hurled a 7–6, 11-inning victory to defeat the Chicks.

As revenues fell, individual teams' funds were limited to advertise nationally as a way of recruiting scattered baseball talent.
