Puerto Rico Best Boxing is planning a big show on May 6 at the gym in Pedrín Zorrilla, which is located in Hato Rey, Puerto Rico. Featherweight Jonathan ‘Polvo’ Oquendo (20-2, 13 KOs) is going to headline the card. The event will be another edition of PR Best Boxing's new televised series, A Puño Limpio. On that same card, flyweight prospect McWiliams Arroyo (7-1 and 6 KO's) will take part in a six round super flyweight bout.
