The country lost yet another champ as Rev Santillan lost his Oriental and Pacific Boxing Federation (OPBF) welter crown Saturday night after he was knocked out in the fourth round of a scheduled 12-rounder by Japanese challenger Kazuhiko Hidaka at the Korakuen Hall in Tokyo, Japan. Santillan, who was also knocked down in the third round, failed to turn the tide as he was again at the receiving end of a barrage of punches from Hidaka by the fourth, prompting the referee to call a halt to the fight. "Korean referee stopped the fight immediately, as Rev's damage looked so serious," said a Japanese mediaman in a long-distance interview with this writer yesterday. The loss saw Santillan's record dip to 21-2-1, 15 KO's while Hidaka improved to 21-4, 15 KO's. The loss will almost surely mean the Iloilo City-rased fighter will have to go down in the WBC rankings, where he is currently ranked no. 7 by the WBC. Santillan's loss also reduced the country's remaining OPBF champs to just two: super-featherweight Randy "Komong Bato" Suico and minimumweight Rodel "Batang Mandaue" Mayol. Last March 5, Dennis Laurente had also lost his OPBF lightweight title with a split decision loss to Chikashi Inada in the same venue at the Korakuen Hall in Tokyo.
