Coliseo Tomas Dones, Fajardo, Puerto Rico - Super flyweight prospect McWilliams Arroyo improved to 9-1 with his eight knockout, after dispatching veteran Lorenzo Trejo, who replaced Shawn Nichols, at 1.11 of the second round. Arroyo headlined the 4th edition of ‘A Puño Limpio.’ The event was promoted by PR Best Boxing Promotions.

Arroyo had no trouble deciphering his opponent early and when he landed his left hooks to the body and combined it with his straight right hand, he hurt his opponent and dropped him to the canvas twice.

"I knew I was strong and I expected to win this way. I am very happy," Arroyo said.

Heavyweight Carlos Negron (13-0, 9KOs) stopped Reggie Pena (6-8, 1KOs) at 2:36 of the second round. Pena quit after taking hard punishment.

For his part, Camilo Perez (4-0, 3KOs) won a four round unanimous decision, with scores of 40-35, 40-35 and 40-36, over Eduardo Melendez. Perez sent him to the canvas in the third round and was on the brink of a knockout but could not finish him off.

Alberto Mercado improved his record to 4-0 when he defeated by unanimous decision Reggie Canales. Mercado scored a knockdown in the first round.
