 Such change adversely affected the performance of underhand pitchers, but it did not disturbed Earp, because she had developed a blazing fastball and a dropping curveball, showing a good command of her pitches.Earp posted a 20–8 record for a .714 winning percentage in 35 pitching appearances in her first season; collecting a minuscule 0.68 ERA and striking out 192 while walking 32 in 280 innings of work.Her 0.68 ERA was a new single-season record, although Lois Florreich would set a 0.67 ERA in 1949 to reach the all-time mark.
