The Minimumweight sees no change in the top 6 from last month. Below the top 6 however we do see numerous changes, some are understandable whilst others are just mind boggling.
The first change we understand complete, though feel it was delayed, as Vergilo Silvano (previously #7) as dropped out of the rankings after his stoppage loss to Jonathan Taconing in an OPBF title fight. Silvano's absence has allowed several fighters to climb though we can't understand how his compatriot Florante Condes (#9) has jumped from #13 not can we understand how Jesus Silvestre (#11) has kept his ranking despite being beaten by Eduardo Martinez on April 12.
Although the changes are, at times, confusing, we're happy that there are numerous Asian's in the top 15 in fact we have 10 of the top 15 with Wanheng Menayothin (#2), Ryuji Hara (#3), Paipahraob Kokietgym (#4), Merlito Sabillo (#5), Shin Ono (#6), Pigmy Kokietgym (#7), Ali Raymi (#8), Florante Condes (#10), Xiong Zhao Zhong (#12) and Samartlek Kokietgym (#14).
If Minimumweight was confusing then we need to say that Light Flyweight was even more confusing. Whilst champion Donnie Nietes managed to defeat former interim champion Moises Fuente (#4) to leave the WBO with just 1 champion we've some how seen Jonathan Taconing (previously #10) fall completely off the radar and out of the top 15. Very strange and thoroughly confusing.
Although Taconing has gone Asia has kept many of it's other top Light Flyweights with Randy Petalcorin (#5), Rommel Asenjo (#7), Yuki Chinen (#13), Renan Trangco (#14) and Yu Kimura (#15). Incidentally Chinen challenges Kimura for the Japanese title early next month in a bout that could shake up these rankings in a pretty big way.
At Flyweight the first change we see is a positive one with Milan Melindo (#3) having moved up 2 places. Oddly Richie Mrepanum (#10) was unranked last month and is now ranked #10 despite losing to reigning champion Juan Francisco Estrada. Oddly Mepranum's ranking has come at the the cost of Masayuki Kuroda (previously #15) who was beaten in a Japanese title fight by Suguru Muranaka (#6).
We see a little more confusion at Super Flyweight which has seen one or two decisions which have confused us. Firstly Mark Anthony Geraldo (#4) has climbed from #6 despite having little to really explain the climb. Whilst we understand Suriyan Sor Rungvisai (previously #7) has changed divisions we're not sure what's happened to the ranking for Sho Ishida (previously #14) however for Teiru Kinoshita (previously #15) his removal from the rankings is likely down to the fact he's got an IBF title fight lined up for later this year.
In the action packed Bantamweight division we continue to have the mandatory challenger Pungluang Sor Singyu (#1), who of course has had his bout with Tomoki Kameda set for a big date in Las Vegas. Pungluang is joined in the top 10 by just 2 other Asians, his compatriot Suriyan Sor Rungvisai (#6), who has moved up from Super Flyweight, and Filipino Marlon Tapales (#9). Further down the rankings we get WBO Oriental champion Alie Laurel (#12), Nikolay Potapov (#13) and Ryo Akaho (#14), of those only Popatov, previously unranked, is a change from last month.
The top 5 at Super Bantamweight are exactly as they were a month ago with Asian representation courtesy of Nonito Donaire (#2), Genesis Servania (#3) and Sod Looknongyangtoy (#5). The odd thing comes with Ryosuke Iwasa (#7) who has gotten a ranking in a division that he hasn't really fought at. Iwasa's move from Bantamweight has forced both Yasutaka Ishimoto (#8) and Shingo Wake (#11) to drop one place each whilst Akifumi Shimoda (#13) just stays in the rankings.
In the Featherweight division we've seen Chonlatarn Piriyapino (#2) stay where he was but Marvin Sonona (#5) has climbed excellently from #7 whilst OPBF Featherweight Hisashi Amagasa (#10) has climbed one place. The one sad thing here is that we've lost Jun Doliguez (previously #8). Despite the changes we are still expecting Chonlatarn to have a confirmed eliminator in the coming months.
The Super Featherweight division sees just 2 of the top 15 coming from Asia though they are the same men from last month with Terdsak Kokietgym (#3) and Juan Martin Elorde (#10). Both of these men are staying where they were a month ago with very little in terms of changes.
In the Lightweight division the biggest change has surrounded Yuriorkis Gamboa (#6) who has slid in to the rankings and forced the likes of Takahiro Ao (#9) and Denis Shafikov (#10) down one place each. Despite the changes we've managed to see Indonesia's Roy Mukhlis (#14) remain where he was in the rankings. Mukhlis is the only WBO ranked Indonesian in any weight.
At Light Welterweight we've sadly seen Filipino Jason Pagara (#4) drop one place oddly though we've seen Shinya Iwabuchi (#12) climb a place up the rankings whilst former WBA champion Khabib Allakhverdiev (#15) is now given a top 15 place.
At Welterweight we find just one ranked Asian, Ji Hoon Kim (#14) who remains not only where he was last month but also as the only ranked South Korean at any weight.
The only ranked Light Middleweight is Charlie Ota (#9) who has bizarrely dropped 3 places from #6.
In the Middleweight division Matt Korobov (#3) has climbed up one place whilst Afghanistan's Hamid Rahimi (#12) has climbed up 3 places.
The only ranked Super Middleweight is Maxim Vlasov (#14) who remains where he was last month.
We only have 1 ranked fighter again at Light Heavyweight where Dmitry Sukhotsky (#5) has remained where he was a month ago.
Things again haven't changed for us at Cruiserweight where Grigory Drozd (#4) has stayed where he was.
There are no ranked Heavyweights.
