He tasted success with Glentoran, helping them to defeat Glenavon in the Irish Cup final in the 1995–96 season. However, at the end of that season Devine moved to the Brandywell for a combined fee of £42,000 which included Liam Coyle, where he provided backup to Tony O'Dowd as Derry City went on to win the title. Devine was restricted to a limited number of appearances and his highest profile appearance was that in the 1997 FAI Cup final. Derry City, aiming for the double, were rocked with the news of the sudden death of the younger brother of Tony O'Dowd just days before the final and Devine stepped up to take his place between the sticks. They were defeated 2–0 by Shelbourne in Dalymount Park on a weekend where football very much took a back seat.
