WBO Minimumweight Title History

Frequently asked questions

Where does this WBO Minimumweight ranking data come from?

The list is taken from the official WBO ranking publication for this division. Box-Rank formats that published list so you can browse it alongside other months and organizations.

How often are the rankings updated?

Most organizations publish monthly rankings within the first two weeks of each month, though timing can vary. Box-Rank checks for new documents every month and aims to have new lists live within 24-48 hours of official publication.

Why isn't a specific boxer ranked?

A boxer may be inactive, unrecognized by that organization, or recently moved to a different weight class. The table reflects only the officially published top contenders. Extended inactivity, significant losses, or rule violations can also lead to removal.

What does Vacant mean in a ranking table?

Vacant means that organization has not named a champion or holder for that slot in this published list. It is not a ranked boxer. The rest of the contender order still comes from the same official document.
