From 1952 to 1953, Peppas improved her batting averages from .262 to .271. In 1954 she drove in 54 runs and posted career-numbers with a .333 average, 16 home runs, and her only pitching winning season with a 6–4 record and a 3.32 ERA in 13 appearances. Her .333 average was a team's best and the league's fifth highest mark for players who played at least 80 games. When Kalamazoo had to face the Fort Wayne Daisies for the AAGPBL Championship Title, Peppas came through with a stellar performance.
