Arroyo defeated Stephen Regman via submission (arm-triangle choke) at 3:31 of Round 2 in the main event of Dana White's Tuesday Night Contender Series. He was one of four fighters to be awarded a UFC contract at the conclusion of the show.
Arroyo had a distinct size advantage over a fighter probably better suited for the welterweight division, but that's no fault of his own -- even oddsmakers pegged this one as a pick'em. The Brazilian came out aggressive early with heavy kicks to the legs and body of Regman. Left unchecked for the most part, those kicks started to tally up in the second round, and also gave Arroyo an opening to go high. While his shin just grazed Regman's head, it was enough to send him to the canvas, where Arroyo began the fight-ending sequence. It would have been nice to see Arroyo display more boxing when on the feet, as the majority of strikes landed with his hands came on the ground. He was plenty effective with his kicks, but overall striking will be an area to watch as the caliber of competition increases. The 30-year-old will enter the UFC riding a five-fight winnings streak, including back-to-back Contender Series wins (he won a decision last August, but wasn't given a contract).
