In decisive Game 5, Peppas pitched a clutch complete game and went 3-for-5 with an RBI against her former Daisies team, winning by an 8–5 margin to give the Lassies the Championship title in the AAGPBL's last ever game. She received support from Mary Taylor (5-for-5), Balingall (3-for-4) and Schroeder, who drove in the winning run in the bottom of the eight. Peppas finished with a .450 average and collected two of the three Lassies victories, to become the winning pitcher of the last game in the league's history.
