ANAHEIM, Calif. — Golden Boy Promotions has built a loaded undercard packed with elite champions and rising contenders for its March 14 event, headlined by former interim champion Arnold Barboza Jr. (32-1, 11 KOs) against Chicago’s Kenneth Sims Jr. (22-2-1, 8 KOs).
The 12-round welterweight main event streams live worldwide on DAZN from the Honda Center on Saturday, March 14.
Tickets are on sale now, priced at $100, $75, $50, and $25 plus applicable fees. A limited number of Golden Boy VIP Experience packages — featuring exclusive merchandise and premium fight-night perks — are also available via Ticketmaster.com and GoldenBoy.com.
Collazo Defends Unified Crown in Co-Main
In the 12-round co-main event, co-promoted with Miguel Cotto Promotions, Puerto Rico’s unified minimumweight champion Oscar Collazo (13-0, 10 KOs) will defend his WBA, WBO, and Ring Magazine titles against Mexico’s Jesus “Chiquito” Haro (13-3, 2 KOs).
Collazo is coming off a devastating knockout victory over Jayson Vayson in September 2025 and looks to continue his dominant run atop the 105-pound division.
Gabriela Fundora Puts Undisputed Crown on the Line
In a featured championship bout co-promoted with Sampson Boxing, undisputed flyweight queen Gabriela Fundora (17-0, 9 KOs) will defend her titles against WBA Interim World Champion Viviana Ruiz Corredor (10-2, 5 KOs), the Venezuela-born, Australia-based challenger aiming to dethrone one of boxing’s most dominant champions.
The 10-round clash adds even more championship firepower to an already stacked night.
Rocha vs. Diaz Jr. Adds Local Fire
Recently added to the lineup, Santa Ana’s Alexis “Lex” Rocha (25-2-1, 16 KOs) faces former world champion Joseph “JoJo” Diaz Jr. (34-8-1, 15 KOs) in a 10-round welterweight showdown. Diaz Jr., representing South El Monte, moves up in weight to take on the heavy-handed Rocha in what promises to be a high-action bout.
Opening the DAZN broadcast, Bakersfield knockout artist Joel Iriarte (9-0, 8 KOs) meets Los Angeles’ Rock Myrthil (17-2-1, 13 KOs) in an eight-round welterweight contest.
