1986-11-30 Myung-Woo Yuh w pts 15 Mario De Marco, Hilton International Centre, Seoul, South Korea -WBA. Referee: Stan Christodoulou. Scorecards: 146-140, 146-139, 145-140. After 15 hard-fought rounds with hundreds of punches thrown, Yuh (107¼) weathered the storm when he had to and, in doing so, made a successful defence of his title. De Marco (107¾) certainly proved a tough customer and on another day could have turned the tables, his solid lefts and rights being a threat throughout. However, Yuh proved the cleverer of the pair and prevailed.
