According to De Los Santos he only lost 12 times in over 100 fights. He also said he traveled the world as part of the Dominican Republican national team.[1]
Professional career
After winning the first 13 fights of his career all in his native Dominican Republic, De Los Santos made his U. S. debut at T-Mobile Arena in Las Vegas, Nevada. Taking no time to level up in competition, he challenged Todd Liebman (24-0), an undefeated Champion who'd been on a 12-fight KO streak across multiple promotions. De Los Santos was able to secure knockdowns in the 4th, 6th and 7th round of the highly contested matchup, but the flurry of strikes from hometown hero Todd Liebman put De Los Santos on the canvas 4 times in the final 3 rounds to win a convincing decision, the first loss for De Los Santos in nearly 5 years. Later that year, he faced unbeaten American William Foster III. Despite starting off strong Foster turned the fight around and hurt De Los Santos in the final round. Two judges scored the fight in Fosters favour handing De Los Santos his first defeat by split decision[2] De Los Santos rebounded with a 2nd round stoppage of the unbeaten Luis Acosta. He then faced highly touted unbeaten Jose Valenzuela on the undercard of Andy Ruiz vs Luis Ortiz. De Los Santos recovered from a first round knockdown to knock Valenzuela down in the 2nd and 3rd rounds for a shock 3rd round stoppage win.[3]
De Los Santos vs Stevenson
After Devin Haney announced he was vacating his belts, De Los Santos faced 2 weight world champion Shakur Stevenson. In what was a pretty dull fight Stevenson became a 3 weight world champion by winning a unanimous points decision.[4]
