Oscar Collazo fifth WBO mini flyweight title defense

Oscar Collazo, a Puerto Rican boxer, is celebrated for his fifth WBO mini flyweight title defense, highlighting his status as a unified champion also holding WBA and Ring magazine titles since November 2024.

The WBO ring, a customary honor, was presented by Gustavo Olivieri, who became WBO president in November 2024 after serving as in-house counsel and assistant to the previous president.

Collazo’s achievement ties into Puerto Rico’s rich boxing history, which saw a golden era starting in the 1970s, spurred by the opening of the Roberto Clemente Coliseum and the island’s need for new sporting heroes after Clemente’s death in 1972.
