William Zepeda: Boxing Career and Key Results
William “Camarón” Zepeda is a Mexican southpaw lightweight from San Mateo Atenco. Born June 4, 1996, he built a reputation for a high work rate and power before capturing a full world title. Golden Boy Promotions lists his record at 34 wins, one loss and 27 knockouts. Golden Boy’s fighter profile summarizes his career and recent results.
From contender to interim champion
Zepeda’s rise included wins over former world champion Joseph “JoJo” Diaz and former titleholder Maxi Hughes. He stopped Giovanni Cabrera in July 2024, then faced Tevin Farmer for the WBC interim lightweight title in November. Zepeda won by split decision after being knocked down for the first time as a professional. He won their March 2025 rematch by majority decision. Golden Boy’s career record lists the results and dates.
A first loss, then a full world title
On July 12, 2025, Zepeda challenged Shakur Stevenson for the WBC lightweight title and lost a unanimous decision over 12 rounds. It was the first defeat of his professional career. He returned to a title opportunity against Lamont Roach Jr. on August 1, 2026, and won the vacant WBC lightweight championship by unanimous decision. The WBC report on the Stevenson fight and Golden Boy’s official profile document both championship bouts.
That victory made Zepeda a full world champion after his earlier interim reign. His pressure and punch volume remain central features of his style, but the title win against Roach marks the clearest milestone of his career so far. See other profiles in our boxing section.
Career Milestones
Zepeda’s wins over established opponents brought him from prospect status into the lightweight contender group. The dated results show that development more clearly than a permanently current description of him as an unbeaten rising star. Each contest belongs to a particular point in his career, and later results can change the record.
