The Minimumweight division really didn't see much of a change at all. The first change was that Francisco Rodriguez, Jr. (#10)burst in to the top 15 and as a result he forced a number of other fighters to drop down. The only other change saw Japan's Ken Agena (previously #14) drop out whilst Ivan Soriano (previously #15) has stayed where he was.
The small number of changes at 105lbs mean that Asia was left with numerous world ranked fighters in the division. These included Wanheng Menayothin (#2), Ryuji Hara (#3), Shin Ono (#5), Pigmy Kokietgym (#6), Ali Raymi (#7), Fahlan Sakkreerin, Jr. (#8), Paipharob Kokietgym (#9), Denver Cuello (#14) and the aforementioned Soriano (#15).
Although their wasn't much in terms of changes in the Minimumweight division there was several at Light Flyweight. The most startling of these has been the fact that Javier Mendoza (previously #1) has dropped all the way down to #8 despite having not lost. Mendoza's remarkable relegation has seen numerous fighters move up one place automatically. One man who didn't move up however was South African Nkosinathi Joyi (previously #4) who has dropped out of the top 15 following his spectacular defeat to Rey Loreto, unfortunately Loreto hasn't been given a ranking as his reward. Oddly, they've also boosted Ramon Garcia (previously #6) all the way up to #3 giving him an additional place somehow. They've also, belatedly, removed Yodmongkol Vor Saengthep from the rankings at 108lbs, an obvious move given he holds the WBA interim title at 112lbs.
With all the movers and shakers, and we've missed at least one, the division does look very different from last month. Thankfully the WBO continue to rank Rommel Asenjo (#5), Naoya Inoue (#7), Randy Petalcorin (#9), Jonathan Taconing (#10), Yuki Chinen (#13) and Renan Trangco (#14). They have also managed to make a space for Japanese national champion Yu Kimura (#15) who is a new entry thanks to Joyi's removal.
At Flyweight the first change is that they've dropped Brian Viloria (previously #3) down to #9. This has seen Froilan Saludar (#3), Kwanpichit 13 Rien Express (#4) and Milan Melindo (#5) all moving up one place. At #6 we again get a belated change with Takuya Kogawa going out and being replaced by compatriot Suguru Muranaka who beat him in a fight back in December. As well as Kogawa dropping out we've also seen Rocky Fuentes (previously #8) dropping 6 places and Yodmongkol Vor Saengthep (#12) ranked at his proper division amongst other changes. A real shake up in all honesty.
With all the movement at 112lbs what we are left with in terms of Asian fighters with world rankings are Saludar (#3), Kwanpichit (#4), Melindo (#5), Muranaka (#6), Joebert Alvarez (#9), Yodmongkol (#12), Toshiyuki Igarashi (#13) and Fuentes (#14). It doesn't need to be noted however that we think the WBO have gotten confused with some fighters as they have them listed for the wrong country, this applies to Kwanpichit (listed as a Filipino), Melindo (listed as a Thai), Muranaka (listed as a Thai) and Hernan Marquez (76, listed as Japanese).
At Super Flyweight the changes, or rather sole change, is an easy to spot one. The only change has seen Mc Joe Arroyo (previously #15) being replaced by Rex Tso.
That means at Super Flyweight we have Koki Kameda (#2), Arthur Villanueva (#3), Mark Anthony Geraldo (#4), Suriyan Sor Rungvisai (#7), Noknoi Sitthiprasert (#9), Olegdong Sithsamerchai (#10), Denkaosan Kaovichit (#11), Teiru Kinoshita (#12), Tepparith Kokietgym (#13) and Sho Ishida (#14) as we did last month and Tso (#15) as an additional entrant.
Bantamweight has seen a big drop for Daniel Rosas (#11, previously #2) following his recent loss to Rodrigo Guerrero. The relegation of Rosas has seen a number of fighters climbing one place as you'd have expected. We've also seen Kohei Oba (#6) swap places with Hugo Ruiz (#7). Everyone else seems to be as they were.
This leaves us with Pungluang Sor Singyu (#1), Ryosuke Iwasa (#3), Marvin Mabait (#5), Oba (#6), Marlon Tapales (#9), Alie Laurel (#10), Ryo Akaho (#13) and AJ Banal (#14) all holding world rankings.
At Super Bantamweight the first change is that Jesse Magdaleno (#4) has had a perfect swap with Hozumi Hasegawa (#6). The only other change is that Shingo Wake (#13) is a new entrant whilst Thabo Sonjica (previously #13) drops out.
This leaves us with Nonito Donaire (#2), Genesis Servania (#3), Sod Looknongyangtoy (#5), Hasegawa (#6), Yasutaka Ishimoto (#7), Akifumi Shimoda (#11), Hidenori Otake (#12) and Wake (#13).
The first change in the Featherweight division has seen Abner Mares (#7) jump into the rankings. Mares's involvement has of course seen a small shuffling behind him, though oddly it's hit Hisashi Amagasa (#12) harder than anyone else with him dropping 3 places. The division has also waved good by to Juan Manuel Lopez which sees some fighters keeping their place in the bottom of the top 15.
The small shuffle in the Featherweight division leaves us with Chonlatarn Piriyapinyo (#2), Jun Doliguez (#8), Amagasa (#12) and Andrey Bogdanov (#15).
In the 130lb Super Featherweight division we see some major changes at the top. The first has seen Juan Carlos Burgos (previously #1) fall all the way down to #6, we also saw Devis Bosciero (previously #2) drop out all together. These changes have helped Miguel Berchelt (#3) move up 3 places with him also leap frogging Maxwell Awuku (#4). the shake ups haven't stopped there, with Yuriorkis Gamboa (#4) jumping straight despite having not been ranked anywhere by the WBO last month. All the shake ups, and some others, have seen, Juan Martin Elorde (#10) dropping 2 places and Juan Manuel Lopez (#13) has of course been given a high ranking despite having been stopped in 3 of his last 6 bouts.
Some of the questionable moves at Super Featherweight have left the Asian representation looking very scarce with just Elorde (#10) given a top 15 ranking. Strange when you consider the likes of Daiki Kaneko and Masao Nakamura are given rankings by other organisations.
At Lightweight the first change is that Denis Shafikov (#3) has climbed over Paulus Moses (#4). Art Hovhannisyan (previously #7) has dropped back down to #10 allowing several fighters to move up, including Takahiro Ao. The division also welcomes Roman Martinez (#11) who really doesn't belong here given his recent form.
As for Asian's at 135lbs we have Shafikov (#3), the adoptive Jorge Linares (#5), Takahiro Ao (#9) and Roy Mukhlis (#14), who is the only Indonesian given a ranking of any kind.
Light Welterweight sees Chad Bennett (#10) drop 4 places, which has helped several fighters up. We've also seen Zahir Raheem (#6) leap frog Karim Mayfield (#7), Viktor Postol (#9) emerge in the rankings and Jay Solmiano (previously #13) drop out.
The rankings at Light Welterweight see only Jason Pagara (#3) and Jimrex Jaca (#12) stay in the top 15.
At Welterweight the first change is that Gabriel Bracero (#10) moves up 2 places and causes a little shake up behind him involving Devon Alexander (#11), Matthias Pelk (#12) and Luis Carlos Abrgeu (#13).
The Welterweight rankings do, rather sadly, make for some bad reading with on Manny Pacquiao (#1) and Ji-Hoon Kim (#9) given Rankings. Kim is the only Asian given a ranking in any division.
Light Middleweight has seen Jermell Charlo (#4) swapping with Charlie Ota (#5) as it's only change. As a result the only Asian with a ranking is the adopted Ota.
In the Middleweight division Billy Joe Saunders (#3) has swapped with Patrick Nielsen (#4), Max Bursak (previously #5) has dropped out causing some fighters to climb a place. Mexico's Gilberto Ramirez Sanchez (#8) has leaped in to the rankings whilst Gabriel Rosado (previously #15) has dropped out.
The changes at Middleweight thankfully hasn't cost Asian fighters too badly and Matt Korobov (#5), Hamid Rahimi (#9) and Daisuke Nakagawa (#14).
The only change at Super Middleweight has seen Maxim Vlasov (#10) and Dimitri Sartison (#11) swapping. Incidentally these are the only two men who matter to us.
At Light Heavyweight the big moved is Jean Pascal (#3) who has hot shot up from #7, as well as this change there has also been a notable drop for Robin Krasniqi (#8) who was #4 last month. Oddly PABA champion Robert Berridge (previously #13) has been dropped out with Emmanuel Danso taking his place.
The only Asian's ranked at 175 Dmitry Sukhotsky (#6) and Igor Mikhalkin (#12) both of whom are Russian.
At Cruiserweight Karo Murat (previously #1) has dropped completely as has Braimah Kamoko (previously #2). In fact the rankings really has seen fighters dropping like flies with Olanrrewaju Durodola (previously #14) and Aleksander Alekseev (previously #15) also dropping out. This has obviously made space for others to slip in to the top 15 in a real shake up month.
The changes at Cruiserweight have resulted in Grigory Drozd (#4) being the only fighter of note to us.
In the Heavyweight division Denis Boytsov (#13) is the only fighter of interest to us and he has stayed where he was though there has been changes in front of him, including the very odd dropping of Bermane Stiverne (#12) by 4 places.
