There have been no changes at all in the Minimumweight division.
At Light Flyweight we've seen Fahlan Sakkreerin Jr (previously #3) lose his place following an unsuccessful challenge against IBF Minimumweight champion Katsunari Takayama. Strangely we've seen Akira Yaegashi (#3) take a huge boost up the ratings by climbing 6 places, despite making it seem clear that he has no intention of fighting at 108lbs again. Even more strange is the fact that both Milan Melindo (#6) and Jonathan Taconing (#7) have each dropped a place. The talented Yu Kimura (#9) has climbed a place as has the unbeaten Nawaphon Por Chokchai (#11).
The bigger at Flyweight this month has been Froilan Saludar (#3) who has climbed 5 places following his recent win over Faris Nenggo. As a knock on effect from Saludar's climb we've seen Kwanpichit Onesongchaigym (#8) move up a place and space has been made for Yodmongkol Vor Saengthep (#9) to climb into the ratings. Another new entry is Macrea Gandionco (#14) who is ranked following his win over Xiang Jing (previously #14).
At Super Flyweight we've seen Japanese champion Sho Ishida (#11) drop a couple of places after his recent title defense against Taiki Eto. We've also seen talented Filipino Jerwin Ancajas (#13) drop a place whilst Oleydong Sithsamerchai (previously #13) has slipped out of the top 15.
There haven't been any changes at Bantamweight, which looks strange given that Alie Laurel (#13) was beaten by Ernesto Saulong a little while back. We'll put this down to an over-sight however.
At Super Bantamweight we've seen a few perplexing changes. Firstly we've seen Nonito Donaire (#5) fall a place, due to former KO victim Fernando Montiel being randomly given a #4 ranking. We've also seen Ryosuke Iwasa (#7) fall a couple of places in a division that he still shouldn't be ranked in. Lower down we've seen Hisashi Amagasa (#13) drop a place.
The Featherweight division has seen a small shake up which has helped Satoshi Hosono (#6) and Chonlatarn Piriyapinyo (#8) both climb a place whilst Hiroshige Osawa (#13) has been boosted a couple of places up the rankings.
There is also a small boost at Super Featherweight with Juan Martin Elorde (#8) climbing a single place.
In the Lightweight division we've lost Takahiro Ao (previously #1) following his defeat to Raymundo Beltran. As a knock on of Ao's loss we've seen both Daud Cino Yordan (#12) and Yoshitaka Kato (#13) each receive a boost of a single place.
More single place climbs at Light Welterweight as Jason Pagara (#5) and Adones Cabalquinto (#14) have both taken a small step up the proverbial ladder.
Yet another single place climber is found at Welterweight as Fariz Mammadov (#11) has been moved up slightly.
At Light Middleweight Sirimongkol Singwancha (#8) has moved up a place.
A big move at Middleweight has seen Ryota Murata (#11) enter the rankings courtesy of his recent victory over Douglas Damiao Ataide, who had previously been ranked #15.
There have been no changes involving an Asian at Super Middleweight, with Yuzo Kiyota (#14) holding on to his ranking.
Unfortunately no Asian fighters are currently ranked by the WBO above Super Middleweight.
