At the State Farm Arena in Atlanta, rising junior middleweight prospect Xander Zayas (11-0, 8 KOs) continued to make his case for winning the 2021 Prospect of the Year honors.

The Puerto Rican boxer won his fifth fight of the year, battering Dan Karpency (9-4-1, 4 KOs) until Karpency's corner stopped the slaughter after the fourth round.

Zayas landed nearly 50 percent of his power shots (81/166) and became the first man to knock out Karpency, who has been a pro for eight years.

The unbeaten boxer is now hoping to land a spot on Top Rank's scheduled card on December 11 at the Hulu Theater at Madison Square Garden in New York City. Super middleweight prospect Edgar Berlanga was set to return as part of that event, but he was pulled after suffering a biceps injury in his last fight.

Zayas said, “My debut on ESPN, I feel amazing. I stopped a guy that had not been stopped in eight years {as a pro}. I’m blessed to be here. I hope everybody enjoyed the show, and now it’s just back to the gym. Hopefully, I can get on that December 11 show in New York.

“In my last fight in September, we noticed that my left hand was a low a little too much, so this camp we kept the elbows and shoulders up and tried to avoid that right hand. We knew he was going to come with those hooks, so we stayed low. Overall, I think I made an improvement. I showed I could adjust, and I hope everyone enjoyed it today.”
