1978-11-12 Ricardo Cardona w pts 15 Soon-Hyun Chung, Changchung Gym, Seoul, South Korea - WBA. Referee: Luis Sulbaran. Scorecards: 147-145, 145-143, 145-150. Following a tough, gruelling affair, the fans let vent to their feelings after their man, Chung (122), was adjudged to have lost. The challenger, carrying a badly cut left eye from the sixth, had been the aggressor throughout but had been picked apart with jabs and hooks from Cardona (121¼), who just about held on to his title. It had been a tough fight for Cardona, especially when he was saved by the bell to mark the end of the tenth.
Following the fight, and having allowed the dust to settle, Cardona agreed after being requested to do so by the WBC he would give Chung a rematch.
