Lester “El Fenix” Martinez is Guatemala’s most important professional boxer — a 30-year-old super middleweight contender with a legitimate claim to being one of the most underrated fighters in the 168-pound division. Unbeaten in nineteen professional bouts across six years, with sixteen stoppages and an 84% KO ratio, Martinez generated global attention in September 2025 when he took unbeaten WBC interim champion Christian Mbilli the full twelve rounds in a fight widely considered the most exciting of 2025 — only to be denied the win by a split decision. The WBC named it Fight of the Year. Martinez fights on, undeterred, and faces Immanuwel Aleem on March 21, 2026 for the WBC interim super middleweight title.

Career Analysis & Highlights
The Amateur Chapter — A National Pioneer (2009–2018)
Martinez began boxing at twelve in Guatemala’s Petén Department and quickly moved to the capital to develop his craft. He became the first Guatemalan to medal at an AIBA World Championship when he took silver at the 2012 Youth World Championships. In 2018, he made history again by winning the middleweight gold medal at the Central American and Caribbean Games — beating former world and Olympic champion Arlen López in the final to become the first Guatemalan to win that title in 68 years. He signed with Latin ARMS Promotions and trained under the legendary Mexican trainer Ignacio Beristáin before turning professional.
An Unblemished Record — From Mayorga to Mbilli (2019–2025)
Martinez turned professional in April 2019 with a stoppage of former world champion Ricardo Mayorga — then 46, but still a recognisable name — and has not tasted defeat since. He worked steadily through the Guatemalan and American club circuit, developing his reputation as a punishing finisher. The breakthrough came in March 2025 with a fourth-round stoppage of Joeshon James for the WBC interim super middleweight title, which elevated him to the WBC’s top ranked position and set up the Mbilli opportunity that September on the Crawford vs Canelo undercard at Allegiant Stadium in Las Vegas.
The Mbilli Fight — WBC Fight of the Year (2025)
September 2025 in Las Vegas. Mbilli arrived undefeated at 29-0 with a reputation as one of the most explosive finishers in boxing. Martinez arrived as the challenger who nobody expected to last twelve rounds. What followed was 685 combined punches over a full fight, with one judge scoring it for Martinez, two for Mbilli, and the WBC handing it its Fight of the Year award. Mbilli retained his title. Martinez retained his dignity, his unbeaten record, and the respect of everyone who watched. The rematch was ordered — then fell apart after Crawford’s retirement reshuffled the promotional landscape and elevated Mbilli to full champion.
2026 — The Road Back to a Title Shot
Martinez fights Immanuwel Aleem on March 21, 2026 for the WBC interim super middleweight title on ProBox TV. A victory reinstates his position as the mandatory challenger and keeps the path to Mbilli — or to Canelo Alvarez, who remains the most commercially significant name at 168 pounds — intact. For a fighter from a country where boxing has no promotional infrastructure and no established world champion, every win Martinez earns is genuinely pioneering.
Lester Martinez Fighting Style
Martinez is a relentless pressure fighter with exceptional hand speed for 168 pounds and a right hand that has stopped sixteen opponents across twenty professional bouts. He attacks the body early and in volume, setting up head shots by forcing opponents to adjust their guard. His 84% KO ratio is elite and speaks to a finishing instinct that is difficult to manufacture — when Martinez hurts someone, he closes the show. The Mbilli fight demonstrated that he can sustain output at world level across twelve full rounds, which was the one genuine question mark over his candidacy before September 2025.
