In 1988 South Korean fighter Soon-Jung Kang attempted to claim the WBC Light Flyweight title, unfortunately he came up short against German Torres. Torres had lost a trio of bouts for the same title to Jung-Koo Chang though when "Korean Hawk" retired Torres managed to finally win the belt with a win over Kang, it was Torres's 5th world title bout. Sadly for Kang he retired after this fight though Korean fans got the last laugh with Yul Woo Lee stopping Torres for the title in 1989, in what was to be Torres final world title bout.
In 1992 Katsuya Onizuka recorded the second defense of the WBA Super Featherweight title as he clearly beat Mexican challenger Armando Castro with a 12 round decision. Onizuka would defent the belt until September 1994 when he finally came up short losing his title, and unbeaten record, to Hyung-Chul Lee in what was a genuine upset. Following the loss Onizuka retired though Lee's reign was a short one with the South Korean losing the belt in his second defense, albeit controversially, to Venezuelan fighter Alimi Goitia.
In 1995 former WBA Bantamweight champion Luisito Espinosa claimed the WBC Featherweight title as he defeated Manuel Medina to become a 2-weight world champion. The bout was a very close one with neither man really managing to dominate the contest, though a rematch in 1997 did see Espinosa take a clear win, albeit by technical ecision.
