1989-06-11 Myung-Woo Yuh w pts 12 Mario De Marco, Dankook University Gym, Seoul, South Korea - WBA. Referee: Rudy Battle. Scorecards: 118-113, 118-115, 119-114. After three fairly close rounds, the champion moved up a gear to punish his challenger with swift one-twos over the next few rounds before ambushing his rival in the seventh and eighth rounds with telling blows to head and body. De Marco (107½), scoring well with left jabs and straight rights, came back strongly in the last four sessions as Yuh (107½) tired, but was unable to change the course of the fight.
