Ramirez (41-0, 27 KO) fights for the third time since vacating his title after five defenses, having tested the 175-pound waters with one-sided wins over Tommy Karpency and Alfonso Lopez. Barrera (22-3, 14 KO) represents his first true light heavyweight test, though he hasn’t fought since a June 2019 loss to Jesse Hart.
“I’m excited to be headlining this show in Los Angeles with Golden Boy Promotions,” said Gilberto Ramirez. “It’s going to be a great night of boxing with fans back in the stands. I’ve always enjoyed fighting here, and I can’t wait to put on a show to continue my hunt for the light heavyweight championship. I appreciate Oscar and the Golden Boy family for their love and support, and I look will forward to a great night of boxing.”
“I’m excited to have the opportunity to headline such a big card against Gilberto Ramirez,” said Sullivan Barrera. “I know that my opponent is a former world champion with a lot of experience and that he will come very much prepared. However, I feel that I have faced much better opposition. I’ve also spent my entire career in the light heavyweight division, something that will be totally new for him. It will be a difficult fight, but I will walk away with my hands raised in victory.”
Diaz (31-1-1, 15 KO) went from dominating Tevin Farmer in a breakout performance to losing his titles on the scales before drawing with Shavkat Rakhimov; he’d previously missed out on a chance to win the WBA featherweight belt in similar fashion. That presumably won’t be a concern against Fortuna (36-2-1, 25 KO), who had to settle for mauling Antonio Lozada in November among fizzled matchups against Luke Campbell, Jorge Linares, and teh aforementioned Garica.
“I’m stepping in for Ryan Garcia to challenge Javier Fortuna,” said Joseph Diaz Jr. “I wish him nothing but the best. Mental health is a very important matter that people should deal with. I’m excited and ready to go out there and redeem myself to all my fans. I’m extremely focused and locked in. Fight night is going to be a movie. I’ll be putting the whole 130 and 135-pound division on notice.”
“I’m very happy that Jo Jo Diaz has accepted the challenge to face me, as long as after the fight he makes no excuses for getting knocked out”, said Javier Fortuna. “I give Diaz credit for having the balls to fight me. Devin Haney doesn’t have those balls. But after I win this fight, Haney will have 90 days to find them. Haney can run but he can’t hide. Fight me or give up the WBC title!”
Undercard
Golden Boy is proud to announce two spectacular additions to the Zurdo vs. Barrera undercard as Seniesa “Super Bad” Estrada (20-0, 8 KOs) challenges Tenkai Tsunami (28-12-1, 16 KOs) for the WBO Light Flyweight Championship and Hector Tanajara Jr. (19-0, 5 KOs) faces William “El Camaron” Zepeda (22-0, 20 KOs) in a lightweight clash.
The event will take place on Friday, July 9 at Banc of California Stadium in Downtown Los Angeles and will be streamed live on DAZN.
“When it comes to undercards, nobody does it better than we do,” said Oscar De La Hoya, Chairman and CEO of Golden Boy. “For all of us at Golden Boy, it is very important for fans to get their money’s worth when attending our events or watching from the comforts of their home.
That’s why we are committed to providing a full night of competitive action featuring the likes of Seniesa Estrada, Hector Tanajara Jr., William Zepeda and many more.”
Estrada is a 28-year-old world champion from East Los Angeles, California whose immediate goal is to capture gold in three divisions. In March, she faced Anabel “La Avispa” Ortiz to capture the WBA Minimumweight World Title. Now, she looks to capture a belt a 108 pounds to be one step closer to achieving her goal.
“I’m very excited to be fighting in Los Angeles again,” said Seniesa Estrada. “Fighting at home with my family, friends and fans there is the best feeling. LAFC is going to be a great venue for Golden Boy boxing. I can’t wait to win another world title in a second division.”
Tsunami, who will be defending her 108-pound title, is a two-division world champion who has a lot of experience fighting at a world championship level. Although making her United States debut, Tsunami feels she is not at a disadvantage because she has fought over a dozen times in foreign countries.
“I am excited to accept the challenge of young and fast-rising Estrada,” said Tenkai Tsunami. “I know Estrada is a good boxer. But I have superior experience and skills that I have gotten throughout my 16-year career and which I wish to use to be victorious. This is my first fight in the United States, but have fought in Mexico seven times, once in Chile and six times in Korea.”
As mentioned above, Hector Tanajara Jr. of San Antonio, Texas will face fellow Golden Boy contender William Zepeda of San Mateo Atenco, Mexico in a 10-round lightweight battle.
“These are the kinds of fights that will take my career to the next level,” said Hector Tanajara Jr. “A win against a tough, undefeated southpaw contender will show everyone that I am ready for a world title opportunity. I believe in my skills and my talent, and on July 9, I will put them on full display at Banc of California Stadium.”
“I’m ready to face the most difficult challenge of my career in Hector Tanajara Jr.,” said William Zepeda. “I have worked all my life to be able to fight on big stages such as the Zurdo vs. Barrera event. I know that Tanajara Jr. very elusive fighter, but I will do everything in my power to make him stand in the center of the ring and give a real show to all the fans.”
