The bout will be one of 4-titles bouts on the show and it looks to be the most significant on the grand scheme of things with the winner likely to find themselves on the verges of a world ranking.
The bout joins a Filipino Bantamweight title fight between Monico Laurente (25-12, 6) and Marco Demecillo (20-2-1, 15) and a pair of WOB Asia Pacific title bouts involving the grand child of the great Flash Elorde himself. One of those WBO regional title bouts will see Juan Martin Elorde (16-1-1, 7) defending his Super Featherweight belt against Argentinian visitor Hirotsugu Yamamoto (16-10-2, 2) whilst Juan Miguel Elorde (17-1, 9) hopes to capture the Super Bantamweight title when he battles Thai puncher Tabthong Tor Buamas (14-2, 12).
Rufino comes into the bout hoping it'll be third time lucky after having fallen short in 2 previous attempts at winning an OPBF title,. The first of those saw him losing a split decision to Naoki Matsuda whilst the second saw him being stopped in round 8 by Amagasa, just a year ago. As for Melligen this will be his first shot at an OPBF belt, though he did fail to capture a PABA title back in 2012, when he was stopped in 2 rounds by Sukkasem Kietyongyuth.
