At the age of 18, Owen met Maurice O'Sullivan for the 1974 Welsh ABA youth title in O'Sullivan's hometown of Cardiff after reaching the final of the tournament on 4 April. Despite Owen and his father being convinced of his victory, the judges awarded the fight to O'Sullivan who himself offered the trophy to Owen, although he refused to accept it. Owen's father Dick later stated that an official from the Welsh ABA approached him after the fight and confessed how the organisation had been under pressure to ensure O'Sullivan's victory in order for him to be selected for the 1974 British Commonwealth Games in New Zealand. Owen's father was becoming an increasing influence on his son's training especially when the two trainers at Owen's gym began suffering ill-health. When Dick was unable to take training, Owen would run the sessions at the gym for local fighters.
