David Martinez Bio
Miguel David Aceves Martínez, known professionally as David Martínez, is a Mexican professional mixed martial artist who competes in the Bantamweight division of the Ultimate Fighting Championship (UFC). Born on August 3, 1998, in Ecatepec de Morelos, State of Mexico, he carries the ring name Black Spartan Doctor and trains out of Bonebreakers MMA. As of September 16, 2025, he holds the No. 11 spot in the official UFC bantamweight rankings, establishing himself as one of Mexico’s most promising fighters on the global stage.
Early Life and Background
David Martínez was born on August 3, 1998, in Ecatepec de Morelos, a city in the State of Mexico. During his early years, local insecurity prompted his family to relocate to Mexico City, where he spent much of his childhood. The move shaped his outlook, and he grew up in a household that valued resilience and discipline, traits that would later define his approach to combat sports.
As a teenager, Martínez discovered mixed martial arts, a sport that combined striking, grappling, and physical conditioning in a way that suited his competitive nature. He joined the Bonebreakers MMA Team alongside his older sister, Melissa, and the two trained together, building a shared foundation in the sport. The family connection to training helped him stay motivated through the long hours of preparation that professional fighting demands.
Outside of martial arts, Martínez pursued higher education, studying medicine at the National Autonomous University of Mexico, one of the most respected universities in Latin America. He eventually earned a bachelor’s degree, an accomplishment that gave rise to the Doctor portion of his ring name. His academic background sets him apart from many of his peers, reflecting a fighter who balances intellectual discipline with the physical demands of professional MMA.
Path to MMA
Martínez began his professional mixed martial arts career in 2016, competing in regional shows across Mexico. Working out of Bonebreakers MMA, he developed a reputation as a dangerous finisher, with most of his early victories coming by way of knockout. His progression through the regional circuit demonstrated a clear evolution in skill, as he combined sharp striking with growing tactical awareness inside the cage.
By 2018, his record had attracted the attention of Combate Americas, a major Latin American MMA promotion later renamed Combate Global. Signing with the organization marked a major step in his career, placing him on a bigger stage against more experienced opposition. It also positioned him to compete for high-profile championships in the bantamweight division.
David Martinez Career
Early Career (2016-2018)
David Martínez turned professional in 2016 and quickly built a record that highlighted his finishing ability. Competing in regional promotions across Mexico, he developed a striking-heavy style, with most of his wins coming by knockout. These formative years allowed him to refine his techniques under the Bonebreakers MMA coaching staff and prepare for the higher level of competition that would soon follow.
His performances in the regional scene drew the interest of Combate Americas, and in 2018 he signed with the promotion, stepping onto a much larger platform. The transition from regional talent to a roster fighter on a recognized combat sports brand represented a turning point in his young career, setting the stage for his run at championship gold.
Combate Global Breakthrough (2021-2023)
Martínez signed with Combate Americas in 2018, and when the promotion was renamed Combate Global, he remained part of its bantamweight division. After Gustavo Lopez vacated the bantamweight championship, the company organized a tournament to crown a new titleholder, with Martínez among the leading contenders. On May 29, 2021, he defeated Alejandro González by first-round TKO in the quarterfinals, then followed it up with a unanimous decision victory over Alan Cantú in the semifinals on the same night.
Later that same evening, Martínez faced the reigning bantamweight champion Francisco Rivera in the tournament final. Just 17 seconds into the second round, he landed the fight-ending blow and became the new Combate Global bantamweight champion. The dramatic finish announced his arrival as one of the top bantamweights outside the UFC.
Martínez went on to defend the title three times. On May 27, 2022, he stopped Arturo Vergara via TKO in the first round. He followed that with a fourth-round TKO of Axel Osuna on October 7, 2022. On May 28, 2023, he delivered a memorable fourth-round head-kick knockout of Jose Zarauz to retain the championship once more, cementing his status as a dominant force in the promotion before eventually parting ways with the company.
UFC Era (2024-Present)
In 2024, Martínez earned his opportunity to join the Ultimate Fighting Championship through Dana White’s Contender Series. On October 1, 2024, during Week 8 of Season 8, he faced Xavier Franklin and earned a unanimous decision victory. The performance was strong enough to secure him one of the five UFC contracts awarded that season, fulfilling a long-held goal for the young Mexican fighter.
Martínez made his UFC debut on March 29, 2025, at UFC on ESPN 64, taking on Saimon Oliveira. Using a combination of knees and punches, he finished the fight in the first round. The performance was rewarded with a Performance of the Night bonus, marking a memorable entry onto the sport’s biggest stage.
He was later scheduled to face Carlos Vera on September 13, 2025, at UFC Fight Night 259, though the bout was canceled and eventually replaced. Martínez was moved to the co-main event, where he faced veteran Rob Font. He won the fight by unanimous decision, a notable victory that helped him climb into the official rankings at No. 11 in the UFC bantamweight division.
Notable Events and Milestones
Martínez’s Combate Global tournament run stands as one of the defining chapters of his career, capped by his 17-second second-round knockout of Francisco Rivera to win the bantamweight championship. His three successful title defenses further reinforced his finishing ability, while his UFC debut finish of Saimon Oliveira earned him Performance of the Night honors. His unanimous decision win over Rob Font added a ranked veteran to his resume and pushed him into the UFC’s official top 15.
