1990-01-31 In-Chul Baek w rtd 7 Yoshiaki Tajima, Hyundai Indoor Gym, Seoul, South Korea - WBA. Referee: Pinit Prayadsab. Proving far too strong for Tajima (166½), the champion put him down in the second round with a countering right uppercut and gradually worked him over with punches that came from all angles. By the fourth the Japanese southpaw was carrying a swollen right eye, testament to the pounding he had received, and after Baek (168) had continued to batter him right through to the end of the seventh he was retired during the interval.
