WBC #17 ranked OPBF 140-pound champ Jungbum Kim (26-3-1, 21 KOs), 140, from Korea, retained his regional belt as he put on a gory game with OPBF top contender Daigoro Yamamoto (10-3-3, 8 KOs), 140, and finally dropped the Japanese challenger for the fatal ten at 1:46 of the seventh round on Sunday in Osaka, Japan. Kim, who had lost to Arturo Morua in the US last year, proved still strong in Asia as he had the upper hand over the game and gallant Japanese challenger, who recklessly mixed up with the onrushing Korean from the outset. Both bled from the nostrils in the second, and Kim sustained a gash over the eyebrow in the third. They kept swapping punches toe-to-toe, but Kim was more accurate and effective in exchanging hot rallies in the close quarter. Kim’s right uppercut following busy combinations sank Yamamoto, who failed to beat the count by Australian referee Charlie Lucas.
