Fighter Matchups and Breakdown
This minimumweight title bout pits a dominant unified champion against a regional contender stepping up significantly. Collazo (29) is a southpaw with elite power (77% KO rate), precision, and body work, holding advantages in experience against top opposition and finishing ability. Haro (23) is an orthodox fighter with youth, hunger, and a solid chin, but limited power (15% KO rate) and unproven at world level. Heights are similar (~5’1″-5’2″), with Collazo’s southpaw stance potentially troubling Haro’s orthodox setup in close-range exchanges. Expect Collazo to control range and pressure for a finish, while Haro aims to survive early and use volume if it goes long.

Collazo’s career (debut 2020) has been a rapid rise to unified champ with six+ defenses. Haro (debut ~2020) has a domestic/regional resume with losses to better competition, making this his breakout opportunity but a tough ask against one of the division’s best.
