Mario Barrios improved to 20-0 with his 12th career knockout Tuesday night, stopping Naim Nelson in a super lightweight contest.
The event aired live on FOX Sports 1.
In the seventh round, Barrios finished off Nelson (13-4) inside the Sands Bethlehem Events Center in Pennsylvania.
“I apologize to the fans of Pennsylvania as I wanted to put on a show tonight,” said Barrios. “After I caught him, he was trying to survive. He was moving around. I did not concentrate if he hurt his shoulder or not.
“I just want to keep moving along and get better. I want to fight again before the end of the year if possible and I know I will put on a show in my next fight.”
In another bout that took place, Thomas Velasquez and Tyrone Jones fought to a draw in a lightweight contest.
“I had to use the jab in this fight as well as my double-jab and body shots were working well,” said Velasquez. “This was a great learning fight and I felt that I won. I can’t wait to get back in the gym, apply what I learned and get back in the ring again soon.”
Velasquez is mentored by former world champion Danny Garcia. Each fighter earned a 59-55 scorecard, while the third had it 57-57.
“This was a tough fight against an undefeated guy who came in confident,” said Jones. “I countered very well and I got to him. I feel that I won the fight, but sometimes the judges don’t see it that way.”
Earl Newman and Paul Parker also fought to a draw to open the card.
