In a one-sided affair, WBO and WBA minimumweight champion Oscar Collazo retained his titles with a dominant performance against challenger Jesus Haro, who was outmatched and outclassed throughout the fight. Elsewhere, Gabriela Fundora knocked out Viviana Ruiz in the sixth round to successfully defend her IBF, WBA, WBC, and WBO flyweight titles.

Why it matters

Collazo's victory highlights his dominance in the minimumweight division, as he continues to cement his status as one of the top fighters in the weight class. Fundora's knockout win over Ruiz demonstrates her punching power and ability to stop her opponents, further solidifying her position as a top flyweight.

The details

Collazo was simply too fast and too powerful for Haro, who tried to adopt a defensive strategy but had neither the speed nor the power to keep the champion at bay. Collazo controlled the fight from the start, landing powerful left hands to Haro's body and straight rights. He broke Haro down over the course of the fight, with Haro's resistance fading as he was unable to escape the relentless onslaught. Fundora, who enjoys a significant height and reach advantage over most female flyweights, used her jab and straight lefts to halt Ruiz in the sixth round.

• Collazo was defending the WBO title for the seventh time and the WBA for the fourth time.
• Fundora was defending the IBF, WBA, WBC, and WBO belts.
