McWilliams Arroyo TKO5 Abraham Rodriguez ... Puerto Rico's McWilliams Arroyo defeated late-replacement Abraham Rodriguez of Mexico via TKO at 1:40 of the fifth round to become the interim WBC flyweight champion. Rodriguez got the fight when WBC champion Julio Cesar Martinez claimed a hand injury on Thursday. Rodriguez is a natural 105 pounder who jumped up in weight for this opportunity. Arroyo (21-4) dominated the first four rounds, including knocking down Rodriguez (27-3) in the fourth. Arroyo made sure Rodirguez didn't see the end of the fifth. He got Rodriguez against the ropes and started unloading one heavy shot after another. Rodriguez's corner was ready to throw in the towel when the ringside doctor jumped on the apron and told the referee to stop it. source: dazn
