LOS ANGELES (Dec. 18)Joseph “Jo Jo” Diaz Jr. (19-0, 11 KOs) retained his undefeated status and was crowned the new NABF featherweight champion after a stunning second round technical knockout of Mexico City, Mexico’s Hugo “Olimpico” Partida (20-7-2, 15 KOs) in front of nearly 1,500 fans at a jam-packed Fantasy Springs Resort Casino tonight, televised live on Boxeo Estelar on Estrella TV.

 

“We came with a great game plan to land effective shots right away and to dig to the body and try to hurt him,” said Diaz Jr. “I dug into the body in the first round and had him hurt. And then I put some good powerful shots on top and got him out. He connected with a good shot, but I didn’t feel anything at all. I just acknowledge him for getting a good shot in. I didn’t let it affect me at all. I knew that I had to take care of business and get the win no matter what. I hope to get the top 10 guys in my division, fight on the bigger networks and get a title shot by the end of next year. I feel very strong at this weight, and I make the weight pretty good. I just feel like 126 is going to be my weight.”

Former two-time world heavyweight title challenger Earnie “The Black Destroyer” Shavers was in attendance at Fantasy Springs Resort Casino for the fights after hosting a special meet and greet for ticketholders before the Boxeo Estelarbroadcast began.

Also in attendance was newly crowned WBC Super Featherweight World Champion Francisco “El Bandido” Vargas, who was joined by Golden Boy stable mates Randy “El Matador” Caballero, Mauricio “El Maestro” Herrera, Christian “Chimpa” Gonzalez, Nick Arce, Oscar “Jaguar” Negrete, and Roy “Pitbull” Tapia ringside at the fight.

In the evening’s co-main event, Andrew “Chango” Cancio (16-3-2, 12 KOs) made a triumphant return to the ring after a year and a half lay off with an impressive technical knockout of Nicaragua’s Rene “Gemelo” Alvarado (22-6, 15 KOs) in a 10-round featherweight bout. Both fighters fought aggressively, producing a slugfest that entertained the raucous crowd. Cancio rallied and unleashed with a flurry of punches in round five but Alvarado passed the test and fought back furiously. The slugging continued until the referee waved off the fight in the eighth round as Alvarado succumbed to the fast punches Cancio was throwing.

 

“We knew that it was going to be a tough fight,” said Andrew Cancio. “Rene Alvarado comes and gives it his all. I mean, he went toe-to-toe with Jo Jo Diaz Jr. earlier this year. We trained hard for this, but we felt we were stronger, harder, and faster. We trained our butts off for this. I felt some ring rust. I thought, ‘man this is a really hard fight,’ it was harder than I anticipated. I knew it was close; some rounds were mine and some rounds were his. Once my corner told me he was hurt, I started throwing combinations. I landed an uppercut and a right, and he just couldn’t get himself together so I got the TKO victory.”

 

Opening up the Estrella TV broadcast, Chinese heavyweight sensation Taishan (6-0, 3 KOs) retained his undefeated status with a win by unanimous decision over Guadalajara, Mexico’s Daniel Arambula (3-2, 1 KO) after a tough four-round heavyweight bout.

 

“I’m not very happy because I wanted the knockout,” said Taishan. “I had a lot of practice, but I think I still need to train more.

 

Topping the undercard fights for the evening, Oscar Torres (7-0, 4 KOs) battled Evincii Dixon (6-13-1, 2 KOs) to retain his undefeated status, winning their six-round welterweight bout by unanimous decision.

 

“We were prepared for this fight,” said Torres. “In the opening, he was very slick. He has a lot of experience, but I worked out in the gym and was ready for that. He didn’t surprise me. He was very strong. I punched him very hard, but he didn’t react, it was like nothing to him and he remained calm. I was ready to fight and I did. He is a good fighter, too.”

 

Los Angeles fan-favorite Rafael Gramajo (6-1-1, 2 KOs) made his third appearance at Fantasy Springs Resort Casino in a six-round super bantamweight war against Michael Gaxiola (4-5) of Modesto, Calif. Gramajo was named the winner by unanimous decision after a tough fight against Gaxiola that went the full six-rounds.

 

“We put in work, we did pressure, we fought a fight and that is what we came to do,” said Rafael Gramajo (6-1-1, 2 KOs). “We knew we would have to be aggressive. I started off slow to work the guy and check him out to see what he’s got, and we knew we had to start working. He was a tough opponent. Thank you to Golden Boy Promotions and my team at Westside Boxing Club for their support.”

 

The evening’s first heavyweight fight had Bostonian Donnie “Big Nasty” Palmer (7-0-1, 6 KOs) facing off against Lansing, Michigan’s Tommy Washington (6-8, 2 KOs) in a six-round bout. Washington suffered a knock down in round two but rallied to come back strong at the beginning of round three. Both fighters persevered round-by-round and went the full six scheduled rounds and it was Palmer that was named the winner by split decision.

 

“I think I had a late start,” said Palmer. “I was a little bit sluggish. I got a knock down, and I should have capitalized on that. He (Washington) gained more confidence as the fight went along, and then the fight became a little harder. He is a great fighter – he did awesome. Thank you to Golden Boy for the opportunity. It was a humbling experience. I need to hit the gym some more.”

 

In the second fight of the night, Indio native Marco Magdaleno (2-0, 1 KO) battled Portland, Oregon’s Derick Bartlemay(0-1), who made his professional debut, in a four-round super lightweight bout before a hometown crowd. Both fighters showed speed and stamina in the ring during the bout that went the full four-rounds. In the end, the judges crowed Magdaleno the victor by unanimous decision.

 

“I felt great tonight,” said Magdaleno. “He was a tough opponent. He came out to fight and that is exactly what he did; he gave me a really good fight. I think I landed the bigger, better punches. I didn’t work how I wanted to but every punch I threw I made sure it landed and was a clear shot.”

 

The Ring TV live stream opened with Jon Jon Dinong (1-0, 1 KO) making a stunning professional debut against Ft. Smith, Arkansas’ Deartie Tucker (2-4, 2 KOs) winning by knockout in the second of a four-round super welterweight bout.

 

“I was trying to stay pretty relaxed and keep calm. I noticed I wasn’t getting as many shots in the first round because I think I was too relaxed. I came back to the corner after the first round, and they told me to pick it up a bit so I came back and got him in the corner, threw punches and then got him,” said Dinong.

 

Diaz Jr. vs. Partida was a 10-round featherweight bout for the vacant NABF featherweight title presented by Golden Boy Promotions and sponsored by Corona Extra and Carmelita Chorizo. Doors opened at 5:00 p.m. and the first fight was at 5:15 p.m. The Boxeo Estelar broadcast aired live on Estrella TV at 10:00 p.m. ET/7:00 p.m. PT.

ISMAEL FLORES** Habiendo obtenido un par de victorias por KO en 2025, el contendiente inmaculado en ascenso Isaac “Puro México” Lucero buscará llevar ese impulso al 2026 cuando enfrente a su también invicto compatriota Alan Sandoval, quien debutará en Estados Unidos en este duelo súper welter a 10 rounds. Lucero (18-0, 14 KO) se profesionalizó en 2019 tras una trayectoria amateur en la que obtuvo cinco medallas nacionales representando a México. Originario de La Paz, Baja California Sur, México, Lucero ha noqueado a sus siete últimos rivales, llegando al 2 de mayo, además de contar con dos victorias por decisión unánime a 10 asaltos. Con el objetivo de consolidar su llegada a Estados Unidos, Lucero ha establecido su campamento en Las Vegas, donde entrena bajo la tutela del reconocido preparador Bob Santos. Recientemente, en diciembre, Lucero dominó al veterano Roberto Valenzuela Jr. y detuvo el combate al final del octavo round. “Estoy muy agradecido con mi equipo y con todos los que trabajaron para hacer esto posible”, declaró Lucero. “Pelear el fin de semana del Cinco de Mayo es el sueño de todo boxeador mexicano, y acepto este reto con la máxima profesionalidad, ya que enfrentaré el desafío más importante de mi carrera en este gran escenario. ¡Les demostraré a todos por qué esta cartelera será ‘Puro México’!” El argentino Flores (17-1-1, 12 KOs) se mudó a España para buscar cumplir sus sueños como boxeador, y se ha destacado desde el 2021. Este pugilista de 27 años ha prevalecido en siete peleas consecutivas, cinco antes de que suene la campana final, desde que perdió por puntos ante Jorge Fortea en el 2023. Más recientemente, Flores le agregó dos triunfos por nocaut a esa racha en el 2025, apabullando a Johan Nova en dos rounds en marzo, antes de detener a Oliver Quintana Sánchez en octubre del año pasado. “Estoy muy entusiasmado con esta pelea. La pelea que vengo queriendo hace tiempo”, dijo Flores. “Esta pelea me va a cambiar la vida. Nunca dejé de entrenar, así que siempre estuve más que listo para aprovechar esta oportunidad. Estoy en gran física y daré el batacazo. Llego a Estados Unidos para quedarme por mucho tiempo”. **JORGE CHÁVEZ VS. TITO SÁNCHEZ** En una atractiva pelea del peso súper gallo, dos contendientes invictos en ascenso se enfrentan cuando Jorge Chávez y José “Tito” Sánchez entren al ring para protagonizar un duelo a 10 asaltos que otorgará al ganador la victoria más importante de su carrera en su camino hacia un título mundial. El chihuahuense de 26 años, Chávez (15-0-1, 8 KOs), regresa a la acción tras iniciar el 2026 vengando la única mancha en su historial. En enero, Chávez se impuso por decisión unánime ante Manuel Flores, después de que ambos pugilistas hubieran empatado por decisión mayoritaria en julio pasado. Originario de Tijuana y ahora entrenándose basado en Orange County, los dos encuentros de Chávez contra Flores fueron sus primeras peleas a 10 asaltos, luego de ganar por decisión dos combates previos a ocho rounds con marcadores casi perfectos. Profesional desde 2021, la victoria de Chávez en enero también le valió el título estatal de California en la categoría de las 122 libras. “Estoy muy agradecido de ser un peleador de ascendencia mexicana que compite en el escenario más grande del mundo durante un pay-per-view del fin de semana del Cinco de Mayo”, declaró Chávez. “Agradezco a todo mi equipo por esta oportunidad de demostrar mis habilidades en un evento tan importante. He trabajado con ahínco toda mi vida para obtener esta oportunidad y tengo la intención de ofrecer un gran espectáculo el 2 de mayo. ¡Viva México!” Representando a Cathedral City, California, Sánchez (15-0, 9 KOs) es entrenado por el reconocido Joel Díaz mientras busca dejar huella en la división. El púgil de 26 años puso fin a un parate de 15 meses en enero de este año, cuando regresó al cuadrilátero y noqueó en el sexto asalto a Jesús Eduardo Ramírez Rubio. Previamente, Sánchez había completado un impresionante 2024: primero venció por decisión unánime al veterano Erik Ruiz en abril, antes de lograr un nocaut en el octavo round sobre Edwin Palomares en octubre. “El 2 de mayo, por fin, tendré la oportunidad de pelear en una cartelera grande en Las Vegas y cumplir un sueño que he tenido desde niño”, dijo Sánchez. “He entrenado muy duro para llegar a este nivel, y quiero agradecer a mi familia y a todo mi equipo por esta oportunidad de brillar frente al público en Las Vegas durante este gran fin de semana boxístico. Compren sus boletos y vengan temprano a ver un gran espectáculo”.
