The first changes of note come at the Minimumweight division where Shin Ono (#10) has been moved down a weight class after having previously been #14 at Light Flyweight. We suspect this move has been made ahead of a prospective fight between Ono and IBF champion Katsunari Takayama. As well as Ono's move we've also seen recent world challenger Virgilio Silvano (#6) move up two places whilst Mexico's Julio Felix (#6) has dropped several places.
At Light Flyweight we've seen South African Nkosinati Joyi (previously #6) drop out, this has helped make a place in the rankings for his conqueror Filipino Rey Loreto (#15). The same rankings have also seen a place made for Atsushi Kakutani (#14) who is a beneficiary of Ono's divisional change. Interestingly Kakutani does hold a 2012 victory over Loreto.
The Flyweight division has seen Roman Gonzalez (#4) shoot up 4 places from #8, there has also been a place made for Suguru Muranaka (#8) who has been rewarded for his victory, back in December, over Takuya Kogawa. Another notable change here has seen Kazuto Ioka (#10) given his ranking after he gave up his WBA Light Flyweight title.
The Super Flyweight division has seen the IBF ignore the request of the JBC and retain Daiki Kameda as their champion. Behind him we've seen a few changes with Kohei Kono (#9), Go Onana (#12) and Rusalee Samor (#12) each having a little boost whilst Jerwin Ancajas (#15), fresh off the back of his impressive in Macau, breaks in to the rankings.
In the Bantamweight division we've seen few changes that have affected Asian fighters. Kohei Oba (#5) is where he was last month whilst Ryosuke Iwasa (#10) has been moved up 2 places. Of courses we expect these rankings to change dramatically in coming weeks as Oba battles American-Nicaraguan Randy Caballero (#4) in a title eliminator.
At Super Bantamweight we've seen some big movers in the form of Yasutaka Ishimoto (#5) and Mike Tawatchai (#6) who have both jumped an impressive 4 places. Further down the rankings Hozumi Hasegawa (#13) remains where he was ahead of his fight with champion Kiko Martinez whilst Shingo Wake (#14) breaks into the top 15.
Evgeny Gradovich remains the IBF Featherweight champion however behind him we see several big changes with Chonlatarm Piriyapinyo (#5) moving up 4 places and Hisashi Amagasa (#8) moving up a staggering 6 places! The one notable addition here is Marvin Sonsona (#9) though fellow Filipino Vinvin Rufino (#14) is another new addition to the rankings.
The Super Featherweight division has seen Masao Nakamura (#5) move up a single place whilst Filipino Michael Farenas (#4) has jumped a staggering 6 places and moved into serious consideration for another world title fight. Strangely we love the idea of a Nakamura/Farenas fight in a title eliminator style contest which would pit a dynamite puncher against a teak tough foe, an irresistible force against an unmovable object.
Lightweight, which recently saw Miguel Vazquez defending the IBF title against Denis Shafikov (#10), has the most recent challenger drop 7 places Rustam Nugaev (#7) move up 2 places. Takahiro Ao (#11) and IK Yang (#13) are where they were in the last update though both Yoshitaka Kato (previously #12) and Al Sabuapan (previously #14) have been dropped from the top 15. Unfortunately Masayoshi Nakatani, who beat Kato, hasn't been rewarded.
Light Welterweight has seen no changes of note for ourselves with Thailand's Patomsuk Pathompothong (#12) remaining where he was a month ago. Whilst Patomsuk remains the only ranked Lightweight it seems Yoshihiro Kamegai (#8) remains the only ranked Welterweight. Kamegai has however moved up 2 places. Likewise at Light Middleweight Charlia Ota (#9) has remained the only Asian and has also moved up 2 places.
At Middleweight their are no ranked Asians however in the Super Middleweight division Maxim Vlasvov (#11) had dropped 6 places whilst fellow Russian Matt Korobov (#13) has entered the rankings at 168lbs.
In the Light Heavyweight division Dmitry Sukhotsky (#2) is the highest ranked challenger as Andrzej Fonfara (previously #1) has been removed. Sukhotsky is joined by fellow Russian Igor Mikhalkin (#15) who als remains where he was a month ago.
In the Cruiserweight division Rakhim Chakhkiev (#6) has dropped a single place whilst compatriots Alexander Alexeev (#8) and Grigory Drozd (#11) remain as they were. Interestingly however a space has been made for Murat Gassiev (#15).
At Heavyweight things are as they were with Ruslan Chagaev (#3) and Alexander Ustinov (#6), we do however know that these will likely be changing next month with Vyacheslav Glazkov (#9) and Deontay Wilder (#10) both scoring notable victories this past weekend.
