Arroyo remained competitive with Sadam Ali for four rounds. Ali land overhand lefts and rights and power shots to the head frequently, which Arroyo took surprisingly well despite the number of them. Arroyo swung wildly with 'hail Marys' none of which landed. Ali dropped his hands at times and toyed with Arroyo, a dangerous move considering Arroyo perhaps could have gotten lucky with his wild swings, but it didn't happen. In the fifth round, Ali switched tactics, throwing hard body shots to the stomach of Arroyo. A left hook to the body by Ali knocked out a pained Arroyo for the full count of ten at 2:46. Ali's scheduled bout several weeks earlier at Aviator Arena was scratched, so he appeared eager to 'get some work in' here in the second of four televised bouts on the Tomasz Adamek vs Michael Grant fight card at Newark's Prudential Center. Arroyo gave a decent accounting of himself till the bout ended.
