Cork retained the provincial crown in 1927, with Barry-Murphy collecting a second Munster medal following a 5-3 to 3-4 defeat of Clare. He was switched to full-back for Cork's subsequent All-Ireland meeting with Dublin on 4 September 1927. The Metropolitans were well on top in the opening thirty minutes and took a 2-3 to 0-1 lead at the interval. Cork fought back in the third quarter, however, an expert display of goalkeeping by Tommy Daly saved the day by keeping Mick "Gah" Ahern scoreless, as Dublin went on to win by 4-8 to 1-3.
