The main event features Dominican southpaw De Los Santos (17-2, 15 KOs) against the Mexican-born Valenzuela (15-3, 9 KOs) in a 10-round rematch of their memorable 2022 Fight of the Year contender. In their first meeting, De Los Santos stepped in on one day’s notice and earned a sensational TKO victory over Valenzuela, who was a heavy favorite. The fight was nonstop action from start to finish, with the southpaws trading knockdowns in the second round. De Los Santos scored another knockdown in the third, securing the KO after a furious follow-up wobbled Valenzuela.

In the co-main event, Omar Trinidad (20-0-2, 14 KOs) of Los Angeles takes on former world titlist Jerwin Ancajas (38-4-2, 25 KOs) of the Philippines in a 10-round featherweight scrap. Following a dominating Zuffa Boxing debut against Max Ornelas, the 30-year-old Trinidad will face the most experienced opponent of his career in Ancajas, who reigned as super flyweight champion for more than five years.
