Home for the First Time: Olascuaga Defends the WBO Flyweight Title vs. Olympian Martinez on Nov. 14 in Carson

Matchroom made it official Wednesday: WBO flyweight champion Anthony "Princesa" Olascuaga has signed a multi-fight co-promotional deal with Matchroom and Teiken Promotions, and he'll defend the belt against Colombia's Yuberjen Martinez on Nov. 14 at Dignity Health Sports Park in Carson, California.

It's the co-main to Diego Pacheco vs. Darius Fulghum on TNT Sports and DAZN's monthly "The Fight" series — U.S. co-exclusive on TNT, truTV and DAZN, and worldwide on DAZN.

For Olascuaga (12-1, 9 KOs), this is the one he's been waiting on. Five of his last six fights were in Japan. He won the title in Tokyo in July 2024 with a third-round KO of Riku Kano, and his last outing was a ninth-round stoppage of Jukiya Iimura in Yokohama in March. Now the 27-year-old Los Angeles kid finally gets a home date.

"I'm so excited to be fighting in Los Angeles," Olascuaga said in the Matchroom release. "It feels amazing to fight in the city and on the streets where I grew up. LA is home, and fighting in front of my people makes this one extra special."

He also tipped his cap to Teiken's Mr. Honda and to Eddie Hearn: "I'm also very pleased to have the opportunity to work with Eddie Hearn and the Matchroom team once again."

Martinez (7-0, 7 KOs) is a two-time Olympian and 2016 Rio silver medalist who took the WBO Latino strap in May with his seventh stoppage in seven pro fights. On paper, that's a short résumé for a world title shot. Pedigree like his is why promoters still make these fights.

"I'm very happy with this huge opportunity to fight for the WBO Title," Martinez said. "After winning Silver at the Rio Olympics, my dream has been to become World champion." He said he was set to fight Nov. 20 in Colombia when the call came, and he'll finish camp at Nacho Beristáin's gym in Mexico City.

There's more undercard news in the same release. David Adeleye (14-2, 13 KOs) makes his Matchroom and U.S. debut against Alexander Flores (21-6-1, 19 KOs) over 10. Charlie Sheehy (13-0, 8 KOs) meets Gabriel Flores Jr. (27-3, 8 KOs) over 10 at lightweight. Prelims include Zaquin Moses, Nishant Dev, Frank Espinoza and Federico Pacheco, opponents TBD.

Here's the question I'd put a Guess the Rounds pick on: does Olascuaga's pressure get to a 34-year-old pro novice early, or does the old amateur hang around for 12?

The bigger picture stays the same, and it's tangled up with the Inoue-Bam mess at the lower weights. Unifications at 112 have mostly lived in Japan. Hearn and Teiken just gave an L.A. champion a platform on American TV. What they do with him next is the real story.
