Two-time amateur youth world champion 🇺🇸Marc Castro (3-0-0, 3KO) – though is still a young pup at the pro level, has continued to impress, as he is putting himself through the grind, and showing the byproduct of the work that he’s been doing inside of the gym.

Tonight, to finish off the DAZN youtube portion of the card for Canelo Alvarez/Billy Joe Saunders, Castro emerged victorious over Mexico’s 🇲🇽Irving Macias Castillo (9-2-0, 6KO), doing so by way of Referee stoppage in the 4th round. Castro fought as if he were a human pressure cooker, storming out of the gates, getting on top of Castillo, never letting him up, as he chased him around the ring, and inflicted pain throughout. After realizing that Castillo had nothing left to give, the Referee stepped in to call a halt to this fight, and Castro picked up his 3rd knockout, in as many victories.
