Un deportista que aspiraba a fundar una franquicia en Aguadilla logró su cometido en 1939. Para la temporada inaugural, reclutó a George Scales como dirigente, y sumó a los refuerzos Leon Day, John Hayes y Neil Robinson. Durante siete años, afrontó diversos desafíos como propietario del equipo. El estadio que utilizaban, el parque Colón, no se equiparaba al progreso de otras franquicias y, para la temporada 1950-51, era el único sin alumbrado. A pesar de las adversidades, el Dr. Márquez dimitió como presidente de los Tiburones, pero su perseverancia y dedicación fueron reconocidas con su exaltación en 1996.

A sportsman who aspired to bring a franchise to Aguadilla reached his goal in 1939. He enlisted George Scales as manager for the inaugural campaign and added reinforcements Leon Day, John Hayes, and Neil Robinson. For seven years, he faced numerous challenges as team owner.
