ANAHEIM, CA – The scales have spoken, and the stage is officially set for a massive night of boxing at the Honda Center. All eyes were on the headliners today as Arnold Barboza Jr. and Kenneth Sims Jr. successfully made weight for their high-stakes WBO Global Welterweight title clash, scheduled for Saturday night, March 14.
In a deep card featuring multiple world title bouts, the atmosphere at the weigh-in was electric, signaling a pivotal night for several divisions.
The Main Event: Battle for Welterweight Supremacy
Long Beach’s own Arnold Barboza Jr. (32-1, 11 KOs) tipped the scales at a lean 146.2 lbs. He looks to defend his home turf and his WBO Global title against the surging Kenneth Sims Jr. (22-3-1, 8 KOs) of Chicago, who weighed in slightly heavier at 146.6 lbs.
For Barboza, this is a must-win to stay in the conversation for a major world title shot. For Sims, it represents the biggest opportunity of his career to leapfrog into the division's elite.
Co-Main: Collazo Defends Unified Gold
In the co-feature, one of boxing's most technical champions, Oscar Collazo (13-0, 11 KOs), successfully made weight for his defense of the WBO and WBA Super World Minimumweight titles. Collazo weighed in at 104.8 lbs, while his challenger, Jesus Haro (13-3, 2 KOs) of Merced, CA, came in significantly lighter at 103.4 lbs.
Undercard Highlights: Fundora’s Unification & Rocha vs. Diaz
The card is bolstered by a historic women's flyweight unification. Gabriela Fundora (17-0, 9 KOs) looks to defend her IBF, WBA, WBC, and WBO World Flyweight titles. She weighed in at 110.8 lbs, while challenger Viviana Ruiz scaled 111.8 lbs.
Additionally, fan-favorite Alexis Rocha (147.4 lbs) faces off against veteran former champion Joseph "JoJo" Diaz Jr. (147.6 lbs) in a 10-round super welterweight crossroads fight that promises fireworks.
