Olascuaga (12-1, 9 KOs) aims to defend his WBO flyweight title for a sixth time on Saturday when he faces 2016 Olympic silver medalist Yuberjen Martinez (7-0, 7 KOs) at Dignity Health Sports Park in Carson, California.

The matchup will serve as the co-main event for a Matchroom Boxing card on DAZN and TNT's "The Fight" series, which will be headlined by the super middleweight bout between Diego Pacheco and Darius Fulghum beginning at 8 p.m. ET/1 a.m. GMT.

For Olascuaga, a 27-year-old Los Angeles native, the homecoming will mark his first fight under Eddie Hearn after signing with the British promoter last month.

If the results keep coming in, "La Princesa" Olascuaga should be getting a serious push from Hearn, who did the same with lower-weight star Jesse "Bam" Rodriguez.

Inside the walls of the LA Boxing Gym in downtown Los Angeles, career-long coach Rudy Hernandez keeps sharpening the dagger that is the still-developing knockout artist Olascuaga, just like the trainer has done with three-division champion Junto Nakatani.

"I've always told Anthony that he's an overachiever," Hernandez told The Ring. "I believed that he'd be a world champion, but being a world champion is one thing, and defending the title in the way he has is something else. He works so hard, and as he's gotten older, he's a little wiser. He's not as naive as he used to be."

Hernandez used to joke that he worried if Olascuaga could walk and chew gum at the same time. Now, his charge is chewing and spitting out opponents with ease.

The power-punching Olascuaga has really come into his own ever since suffering a ninth-round stoppage loss against then-light flyweight champion Kenshiro Teraji in the sixth fight of his career in April 2023. Seven wins have since followed, six of which have come via knockout.

Olascuaga earned the vacant WBO title by blasting Riku Kano inside of three rounds in July 2024 and title defenses have come against Jonathan Gonzalez, Hiroto Kyoguchi, Juan Carlos Camacho, Taku Kuwahara and Jukiya Iimura last time out eight months ago in Yokohama.

But Olascuaga may still be unfamiliar to even the most die-hard boxing fans because the thick of his professional career has unfolded in Japan. On Saturday, Olascuaga will be fighting in his hometown for the first time in his career on national television with one of the sport's biggest promoters building him up.

"It's a big fight for him at home, and a lot of his friends and family can finally watch him fight in person," Hernandez said. "Tony is in great shape, and he's been in the gym for the last few months. He'll be ready on November 14 in what I believe will be a very tough fight because."

Martinez is even more unknown to the boxing public after scoring the silver medal eight years ago in the Olympics while representing Colombia. The 35-year-old Martinez turned pro in 2022 and has fought his first six fights at home, with the most recent one coming in Panama by stopping the previously unbeaten Angel Bethancourt inside of eight rounds.

"We're fighting an experienced Olympian, even if he may not have the professional experience," Hernandez said. "He seems to be a really good inside fighter. He throws some really nice uppercuts. I think it's gonna be a hell of a fight, and I hope we can win the fans over.

"Before we can think about the title unifications and move on to the next one, we need to worry about Martinez. This is the most important fight of Anthony's career."
