We saw the first change near the top of the Minimumweight rankings with Japanese teenage sensation Kosei Tanaka (#2) being moved up a place, just like Filipino puncher Rey Loreto (#4), who have both been moved following Jesus Silvestre's (#6) loss to Hekkie Budler. Lower down the ranking's we've seen Muhammad Rachman (#13) drop 4 places following his loss to Knockout CP Freshmart (#1) on March 5th.
At Light Flyweight we've lost Filipino fighter Milan Melindo (previously #3) following the news that he will be challenging for the IBF champion Javier Mendoza in a few weeks time. Melindo's removal from the rankings has allowed several fighters to move up a place. Sadly we've also lost Jether Oliva (previously #14) who was was stopped by Luis Nery in Mexico, this has helped create an opening for Kwanthai Sithmorseng (#15) to re-enter the rankings.
We could see only one change in the Flyweight rankings as Filipino fighter Rommel Asenjo (#15) breaks into the rankings ahead of his world title shot against Juan Francisco Estrada. Asenjo's move into the top 15 has come at the expense of Japan's Tetsuma Hayashi (previously #15).
The Super Flyweight division hasn't seen much of a chance though it has seen a notable one with Hong Kong star Rex Tso (#9) moving up a couple of places and forcing both Petchbanrgborn Kokietgym (#10) and Ryo Matsumoto (#11) to each drop a place.
In the Bantamweight division we've sadly lost experienced Filipino Malcolm Tunacao (previously #9), who has been replaced by American Rau'shee Warren.
At Featherweight we've see both Dennis Tubieron (#11) and Hiroshige Osawa (#14) both climb a place following the removal from the rankings of American Gary Russell Jr, who will be fighting in a WBC world title fight.
One of, if not the, most significant change has come at Super Featherweight where Jomthong Chuwatana (#10) has gain crashed the rankings. This is significant as talks have been on going for Jomthong to get a world title fight with current “Super” champion Takashi Uchiyama in May. The ranking for Jomthong now makes that bout look very likely.
At Light Welterweight we've seen Filipino fighter Czar Amonsot (#13) drop a couple of places
