1987-06-14 Kyung-Yung Lee w rsc 2 (15) Masaharu Kawakami, Hawaiian Hotel, Bukok, South Korea - IBF. Referee: Tom Evaristo. Lee (105) became the first IBF mini flyweight champion when he easily stopped Kawakami (104¾) after 31 seconds of the second round had elapsed, the referee rescuing the outgunned Jap to save him from further punishment. With Kawakami being a mere six to eight-round fighter and not even licensed by the Japanese Boxing Commission, it was a mismatch and gave no credit to all concerned.
After Lee relinquished the IBF version of the title in December in order to challenge for the more prestigious WBC crown, Samuth Sithnaruepol and Pretty Boy Lucas were brought together to find a successor.
