Who will walk out of California with the WBA, WBO, and Ring minimumweight titles when Oscar Collazo defends the belts on September 20 against Jayson Vayson?
A Pan American Games gold medalist, Collazo (12-0) has defended the WBO minimumweight title five times since winning it in 2023. He recently added the WBA and Ring belts and is ready to become undisputed at 105.
Waiting patiently, Collazo looks to take care of a game Vayson so he can face the likes of champions Melvin Jerusalem and Pedro Taduran.
“I was willing to fight them, and believe me, I want them, they are holding my titles,” Collazo told The Ring. “They were too difficult to make happen [at this time] and that’s why I had to go this route, but I want it, and after finishing this fight, I want them.”
Vayson (14-1-1) is on a four-fight win streak. The Filipino has eight wins via knockout and competes in the U.S. for the first time.
A world champion in a league of her own will be featured on the Oscar Collazo vs. Jayson Vayson undercard, while contenders and prospects look to impress.
