1977-02-13 Dong-Kyun Yum w pts 15 Jose Cervantes, Changchung Gym, Seoul, South Korea - WBC. Referee: Jay Edson. Scorecards: 146-144, 146-144, 147-144. The challenger started smartly with sharp-shooting left jabs, before Yum (121¼) came back strongly in the middle sessions to score well with sporadic round-arm flurries. It still was not enough though and Cervantes (120) despite tiring was in front by the tenth. But he had never been 15 before and continued to tire while Yum stayed out of range during the last six rounds, scoring with stinging hooks and using hit-and-run tactics to pile up enough points to warrant the decision.
