Devaney won an eighth National League medal as a member of the panel in 1968 as New York were defeated on an aggregate score of 6–27 to 4–22. Tipperary retained their status as provincial kingpins once again and a 2–13 to 1–7 trouncing of Cork gave Devaney an eighth Munster medal. For the fourth time of the decade, Wexford were Tipperary's opponents in the subsequent All-Ireland final on 1 September 1968. At half-time it looked as if Tipperary were cruising to another victory as they took an eight-point lead. Just after the restart Wexford had a Christy Jacob goal disallowed before Tony Doran scored a goal after just six minutes. Tipperary fought back, however, it was too late as Wexford won by 5–8 to 3–12. In spite of this setback, Devaney finished the year with a sixth Oireachtas Cup medal following a narrow 1-9 to 1-6 defeat of Cork, before retiring from inter-county hurling.
