2003-01-13 Sirimongkol Singmanassak w pts 12 Yong-Soo Choi, Korakuen Hall, Tokyo, Japan - WBC. Referee: Frank Cappuccino. Scorecards: 119-109, 119-109, 118-110. Making his first defence, Singmanassak (130) used his superior speed, good footwork and snappy left jab to keep Choi (130) at bay for long periods. Although Choi, whose right eye was damaged before the first round was over, pushed on with heavy rights in the fifth and came again with non-stop aggression in the eighth and ninth he faded thereafter and the champion cruised the remaining three sessions.
