In 1958 Devaney won his first Munster medal from the substitutes' bench as Tipperary regained the provincial crown following a 4-12 to 1-5 trouncing of reigning champions Waterford. Tipperary 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. 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. Tipperary won the game by 4-9 to 2-5 giving Devaney his first All-Ireland medal.
