Arnold Barboza Jr. (33-1, 11 KOs) masterfully outboxed Kenneth Sims Jr. (22-4-1, 8 KOs) over 12 rounds at the Honda Center on Saturday night. A battle of tacticians went Barboza’s way as he was quicker, busier and more accurate for the bulk of the fight.
The welterweight crossroads match headlined a Golden Boy Promotions card broadcast live on DAZN. Official scores were 120-108, 118-110 and 118-110. InTheCorner.Net scored it 118-110.
The fight started slowly, with both veterans cautiously looking for an opening while pawing from the outside. Soon it was apparent that they were each mirror images of each other and while both were looking jab their way in and counter, it was Barboza who was more effective.
Sims started out in a southpaw stance and switched to right near the end of the first round, not uncommon for him. But he only got his shots off in isolated spurts, while Barboza was able to consistently land from the outside and counter when Sims rushed in.
The crowd booed the tactical pace at times, but it was a product of the two very similar styles. With Sims unable to mount a sustained attack, it became one-sided and repetitive.
With the win, Barboza got back in the win column after suffering his only pro defeat at the hands of Teofimo Lopez last May in a junior welterweight match. The step up in weight appeared to be a much-needed improvement.
Sims has now lost two straight following a nine-fight win streak.
OSCAR COLLAZO (14-0, 11 KOs) TKO6 over JESUS HARO (13-4, 2 KOs)
The co-main saw minimumweight champion Oscar Collazo roll over elusive challenger Jesus Haro. Collazo pounded away at Haro with relentless pressure and retained his title when the challenger failed to answer the bell for round seven. Haro was employing slick movement to avoid the heavy hands of the champion, but Collazo was slowing him down with punishing body shots as round six came to an end.
The stoppage was somewhat surprising, as Haro didn’t look like he was broken down, although it was heading in that direction.
ALEXIS ROCHA (26-2-1, 15 KOs) UD12 over JOSEPH DIAZ JR. (34-9-1, 15 KOs)
Southern California favorites Joseph Diaz Jr. and Alexis Rocha went 10-rounds for a unanimous decision victory for Rocha. Official scores: 97-93, 98-92, 97-93.
One-sided on the scorecards, the action in the ring was very entertaining, especially over the second half of the bout. Rocha came back from over a year out of the ring and Diaz came up to 147 pounds for the first time and it turned out to be a firefight.
Rocha had distinct advantages in height and reach and when he utilized them, he proved to be the more effective, heavier-handed fighter. When Diaz was able to crowd him to get off an attack from in-close, Rocha regularly came back with his own shots and won many of the exchanges.
Jojo Diaz lost for the eighth time in his last 10 fights and he has proven to be tough as nails all along the way. Rocha, coming back for the first time since a draw with Raul Curiel in December of 2024, could be reasonable expected to win this fight going in, but it was always going to be a lot of work.
The Los Angeles-area crowd ate up the all-action fight. Rocha called for a fight with Ryan Garcia in his in-ring interview. Diaz likely continues on as a workhorse.
GABRIELA FUNDORA KO6 over VIVIANA RUIZ
Flyweight champion Gabriela Fundora overcame game but overmatched challenger Vivana Ruiz with a sixth-round stoppage. Fundora’s long arms and superior strength carried the day as Ruiz was buried under a furious attack in the final round. The contest was waved off at the 1:25 mark. Ruiz was down in the fourth.
JOEL IRIARTE (10-0, 9KOs) TKO6 over ROCK MYRTHIL (17-3-1, 13 KOs)
Unbeaten welterweight prospect Joel Iriarte turned back Rock Myrthil with a sixth-round stoppage. Myrthil presented a stiff challenge to the much-taller and longer Iriarte, buzzing the young phenom in the second round with a solid right, but over time it was Iriarte’s elite skills that proved to be too much.
