Most promoters consider themselves fortunate to get one talented prospect signed at one time, but PR Best Boxing (Ivan & Peter Rivera) got double with their signing of twins McJoe and McWilliams Arroyo of Puerto Rico today. The Arroyos enter the professional ranks with a wealth of international amateur experience behind them. Both have represented Puerto Rico in several amateur games where they won multiple medals. Games they participated in were the Central American, Panamerican, and World Games. McWilliams won the Gold Medal at the 2009 World Amateur Boxing Games in Milano, Italy. “We are very delighted to have signed the young and very talented Arroyo brothers. Both brothers are determined to become world champions in the future and we as their promoter will more than do our part to get them there and meet that goal.” said PR Best President Ivan Rivera. The Arroyo twins who will debut in February in the flyweight division join a stable that already includes WBO light flyweight champion Ivan ‘Iron Boy’ Calderon, WBO super featherweight champion Ramon ‘Rocky’ Martinez, and WBO junior featherweight champion Juan Manuel ‘Juanma’ Lopez.
