In 1958 Finn won a third Munster medal as Tipperary regained the provincial crown following a 4–12 to 1–5 trouncing of reigning champions Waterford. Tipp later defeated Kilkenny in the All-Ireland semi-final before lining out against Galway in the All-Ireland decider on 7 September 1958. Galway got a bye into the final without picking up a hurley. Liam Devaney, Donie Nealon and Larry Keane all scored goals for Tipperary in the first-half, while Tony Wall sent a seventy-yard free untouched to the Galway net. Tipp won the game by 4–9 to 2–5 giving Finn his third and final All-Ireland medal.
