Although eligible to play with the Douglas club, Bennett transferred to Blackrock who were in the midst of a 25-year era without success. In 1954 he was at right wing-forward as Blackrock qualified for their first county final in six years. The Rockies fielded a young team, however, Glen Rovers had eight inter-county players on their team and held a 2-4 to 0-2 half-time lead. Bennett's side fought back after the interval with goals from Eddie John O'Sullivan, Tom Furlong and Seán Horgan, leaving the result in doubt up to the end. At the full-time whistle Blackrock were defeated by 3-7 to 3-2.
