Oscar Collazo has had a mission since he turned pro in 2020 and he wants to accomplish it as quickly as possible.

He wants to become the undisputed strawweight champion, a division in which no fighter has ever fully unified since its creation in 1987.

The charismatic Puerto Rican won the WBO 105-pound title in just his seventh fight when he knocked out Melvin Jerusalem in the seventh round in 2023. Collazo set the Puerto Rican record for fewest fights needed to win a world title.

In November, Collazo scored two knockdowns and demolished long-reigning and undefeated WBA titleholder Thammanoon Niyomtrong in a seventh-round knockout victory to unify the titles in Riyadh Saudi, Arabia.

Collazo needs the WBC and IBF belts to complete his collection but while those bouts have not immediately been available to him he will make his sixth overall defense and second of the unified title against Jayson Vayson in the main event of the Golden Boy card on Saturday (DAZN, 8 p.m. ET) at Fantasy Springs Resort Casino in Indio, California, the same venue where knocked out Jerusalem for his first world title.

Collazo (12-0, 9 KOs), 28, a southpaw, who traveled to hostile turf in Mexico in March and retained the belts by fifth-round body-shot knockout of Edwin Cano, will face Vayson (14-1-1, 8 KOs), 27, of the Philippines, but with aspirations to further unify.
