Box.Live Power Rankings – Minimumweight

Box.Live's Power Rankings provide a simple method for ranking active fighters 1st through 31st in the minimumweight division.

Outside the top 10 or so fighters, who are more likely to be ranked for their current ability and standing at minimumweight, others are considered by their potential future influence as mandatory or eliminator contenders. Every fighter is either a champion or ranked by at least one organisation at minimumweight, so inactive fighters may not appear until they fight again.

Order: Ring champion, Ring positions 1–10, then other world champions, then by combined ranking points (WBC/IBF/WBO/WBA).

Key: (c) = champion, (int) = interim, (reg) = WBA regular when multiple champions, [m] = mandatory.

One thought on “Minimumweight Rankings & Champions”

At present, the WBO is the only World Title sanctioning body w/ a defined “mandatory” @ 105 lbs(Chacon). So, there is @ bit of time & room to further unify the World Minimumweight Championship between Taduran, Jerusalem, and Collozo…which all three have expressed a desire to get done.
