Anthony Olascuaga Defends His WBO Flyweight Title Against Yuberjen Martinez

Anthony Olascuaga defends his WBO flyweight title against Colombian Olympic silver medalist Yuberjen Martinez on Saturday, November 14, at Dignity Health Sports Park in Carson, California. The 12-round bout is the co-main event under Diego Pacheco vs Darius Fulghum and is Olascuaga's sixth defense of the belt.

Fight Details and Start Time

The title fight sits on a Matchroom card that is part of The Fight, the monthly series from TNT Sports and DAZN. The broadcast begins at 8 p.m. Eastern, or 5 p.m. local time in Carson and 1 a.m. GMT on Sunday. The flyweight title fight comes right before the super middleweight main event between Diego Pacheco and Darius Fulghum.

It is a homecoming of sorts for the champion. Olascuaga was born in Los Angeles but has spent most of his professional career fighting in Japan, and this will be his first fight since signing with Eddie Hearn.

Anthony Olascuaga's Path to the Title

Anthony Olascuaga is 12-1 with nine knockouts and is 27 years old. He trains with Rudy Hernandez at the LA Boxing Gym. He turned professional in September 2020 with a stoppage win in Kissimmee, Florida, and won a regional WBA belt in Panama in 2022.

His only defeat came early. In April 2023, in just his sixth professional fight, he took on Kenshiro Teraji in Tokyo for the WBA, WBC and Ring light flyweight titles and was stopped in the ninth round. The Ring notes he took that fight on short notice. He has won seven straight since then, six of them inside the distance.

Olascuaga won the vacant WBO flyweight title in Tokyo on July 20, 2024, knocking out Riku Kano in the third round. His defenses since then have come at a steady pace, and most of them ended early.

In October 2024 he beat Jonathan Gonzalez in the first round after Gonzalez could not continue following an accidental clash of heads. In March 2025 he went the full 12 rounds for a unanimous decision over Hiroto Kyoguchi in Tokyo. In September 2025 he stopped Juan Carlos Camacho in the second round in Nevada, and in December 2025 he stopped Taku Kuwahara in the fourth in Tokyo. His most recent fight was on March 15, 2026, in Yokohama, where he stopped Jukiya Iimura in the ninth round. That means he has been out of the ring for about eight months.

Yuberjen Martinez Brings Olympic Pedigree

Yuberjen Martinez is unbeaten at 7-0, with all seven wins by knockout. The Colombian won a silver medal at light flyweight at the 2016 Rio Olympics, and The Ring says he also represented Colombia at the Tokyo Games. He turned professional in the summer of 2022 and had his first six pro fights at home.

His seventh fight was his biggest step up so far. In Panama he stopped the previously unbeaten Angel Bethancourt inside eight rounds. He signed with Tuto Zabala's All Star Promotions in the fall of 2025, and for this camp he trained in Mexico City with Hall of Fame coach Nacho Beristain.

His age is listed differently in different places. One Ring article says he is 34 and another says 35. Wikipedia gives his birth date as November 1, 1991, which would make him 35.

What to Expect

The contrast is clear. Olascuaga has 13 professional fights and six world title fights at flyweight, including a 12-round decision, so he knows what the championship distance demands. Martinez brings years of elite amateur experience but only seven pro fights, and this is his first world title fight as a professional. Both men have stopped most of their opponents, so a knockout is a real possibility for either side.
