Edwin De Los Santos Bio
Edwin De Los Santos is a Dominican professional boxer who competes in the lightweight division. Born on 7 October 1999 in Santo Domingo, Dominican Republic, he is recognized across the sport for his heavy hands and finishing instincts inside the ring. With a record built primarily on stoppages, he has emerged as one of the most talked-about punchers in the lightweight class. His career has carried him from the Dominican amateur ranks to marquee nights in Las Vegas.
Early Life and Background
Edwin De Los Santos was born on 7 October 1999 in Santo Domingo, the capital of the Dominican Republic. Growing up in a country with a deep boxing tradition, he was drawn to the sport at a young age and began shaping his skills in local gyms. The Dominican Republic has produced numerous world champions, and De Los Santos grew up surrounded by that heritage of fighters.
As a young athlete, De Los Santos devoted himself to boxing and quickly progressed through the amateur system. According to his own accounts, he lost only 12 times across more than 100 amateur fights, a remarkable ratio that hinted at his professional potential. He also traveled internationally as a member of the Dominican Republic national team, gaining exposure to varied styles and high-level competition. Those formative years laid the foundation for the power-based approach he would carry into the professional ranks.
Path to Boxing
De Los Santos built his reputation on the Dominican amateur circuit before deciding to turn professional. His extensive amateur background, including bouts outside the country with the national team, prepared him for the demands of paid competition. Standing 5 ft 8 in with a reach of 70 in and fighting from a southpaw stance, he entered the professional ranks with a frame and style suited to the lightweight division.
His early professional run was staged entirely in his native Dominican Republic, where he strung together a long string of victories and established a reputation for finishing fights. Those opening bouts allowed him to refine his timing, sharpen his power, and adapt to longer professional rounds. By the time he was ready to cross the Caribbean and test himself in the United States, he had already become a knockout threat worth tracking.
Edwin De Los Santos Career
Early Career (Years Range)
Edwin De Los Santos opened his professional career with an extended unbeaten run in the Dominican Republic, winning his first 13 bouts. Many of those victories came inside the distance, immediately marking him as a finisher rather than a points fighter. The streak established him as a rising name in the Dominican boxing scene and gave promoters a reason to bring him to larger platforms abroad.
His U.S. debut came at T-Mobile Arena in Las Vegas, where he faced unbeaten American William Foster III. After a strong start, De Los Santos was hurt in the final round and dropped a split decision, suffering the first defeat of his professional career. The loss did little to slow his momentum, as he returned shortly after with a second-round stoppage of previously unbeaten Luis Acosta.
Lightweight Breakthrough (Years Range)
De Los Santos produced his signature early statement on the undercard of Andy Ruiz vs. Luis Ortiz, where he faced highly regarded unbeaten José Valenzuela. After being knocked down in the first round, he recovered emphatically, dropping Valenzuela in both the second and third rounds to force a third-round stoppage. The win announced him as a serious force in the lightweight division and gave him a notable scalp against a future champion.
That breakthrough performance earned him the opportunity to fight for a world title on 16 November 2023 against two-weight champion Shakur Stevenson for the vacant WBC lightweight belt. In a remarkably inactive contest, De Los Santos was outboxed and lost by unanimous decision, with Stevenson becoming a three-weight world champion. Despite the defeat, the bout against a top-tier operator confirmed that De Los Santos belonged on the biggest stages of the sport.
Recent Schedule (2024–Present)
Following more than a year of inactivity, De Los Santos was booked to face WBO lightweight champion Keyshawn Davis on 7 June 2025 at the Scope Arena in Norfolk, Virginia. When Davis failed to make the correct weight limit, he was stripped of the title, leaving De Los Santos as the only fighter eligible to win it. Despite lengthy negotiations aimed at keeping the bout intact, the fight was ultimately canceled after the two sides could not reach an agreement.
Looking ahead, De Los Santos is scheduled to meet José Valenzuela in a 10-round lightweight rematch at Zuffa Boxing 8, scheduled for 28 June 2026 at The Chelsea at The Cosmopolitan of Las Vegas in Paradise, Nevada. The booking sets up a high-stakes return against an opponent he has already defeated and gives him a marquee platform to rebuild his momentum.
Style and Strengths
De Los Santos fights from a southpaw stance, a position that creates awkward angles for orthodox opponents and amplifies his natural power. He carries genuine one-punch knockout threat and is known for his composure in finishing sequences once he has an opponent hurt. The combination of reach, southpaw stance, and finishing instinct defines his identity as a puncher-first lightweight.
Notable Events and Milestones
His third-round stoppage of José Valenzuela stands as the defining result of his career so far, marking him as a threat at the highest level of the lightweight division. His world-title opportunity against Shakur Stevenson in November 2023 remains his biggest stage to date, and his upcoming Zuffa Boxing rematch with Valenzuela is poised to be a defining chapter.

2025 Season Performance
Edwin De Los Santos entered 2025 coming off a long period of inactivity following his November 2023 world-title fight against Shakur Stevenson. His momentum hinged on the rescheduled bout with WBO lightweight champion Keyshawn Davis, originally booked for 7 June 2025 at the Scope Arena in Norfolk, Virginia. When Davis failed to make weight and was stripped of the title, the situation shifted toward a non-title main event, but negotiations ultimately collapsed and the fight was canceled.
The canceled bout left De Los Santos without a 2025 ring appearance, a stretch of inactivity that stalled his climb back into title contention. With the WBC and WBO lightweight pictures moving forward, he needed a high-profile stage to remind the division of his power. His booking against José Valenzuela at Zuffa Boxing 8 in 2026 was framed as a statement opportunity to re-establish himself.
Looking ahead, the rematch with Valenzuela offers De Los Santos a clear measuring stick, given their history and his previous stoppage win. A victory would place him back in the lightweight title conversation and give Zuffa Boxing a marquee attraction at The Chelsea inside The Cosmopolitan of Las Vegas. For De Los Santos, the focus is squarely on returning to the ring and converting his signature power into another defining moment.
