Deadwood Mountain Grand in Deadwood, S.D. - In the Showtime televised co-main event, heavy-hitting lightweight Edwin De Los Santos (14-1, 13 KOs) scored a devastating second-round knockout against Luis Acosta (12-1, 11 KOs), who suffered the first loss of his career. Acosta became the 211th fighter to have his undefeated streak snapped in the 21-year history of the prospect series.

“One-hitter quitter for De Los Santos!” SHOBOX analyst Brian Campbell said of De Los Santos’ clean left cross that sent Acosta to the canvas as referee Mark Nelson signaled the end of the fight at 48 seconds in the second round. 

“It was a left hand that was just a thing of beauty,” said International Boxing Hall of Famer and SHOBOX blow-by-blow announcer Barry Tompkins.

Dominican Republic’s De Los Santos landed 19 punches before scoring the fight-ending knockout in his second SHOBOX appearance. 

“I’m back,” said De Los Santos, who suffered a loss in his first SHOBOX appearance in January to William Foster III. “Everyone was counting me out after the last fight. They thought I was done after the loss to Foster. But I’m back. This is the kind of statement that I should have made last time.

"This is a new beginning for me. I thought I was going to catch him later in the fight but the opening came early with the straight left. My preparation was just better this time, I was just more focused and better prepared and this was the result. I’m ready for anyone.”
