Seeking exposition, the team reached an agreement with professional boxer Miguel Cotto, who wore the club's colors in several of his world championship contests. The team's directive underwent several integrations, including Erick Rodríguez as First Vice-President, Kenneth Cintrón as Second Vice-President and Alvaro Nazor as vocal. In 2006, the team's secretary, Eduardo Fabrizi, decided to include Club Atlético River Plate Puerto Rico in the Liga Premier de Fútbol marking its debut. Rubén Muñoz coached a lineup that included Walter Fabian Zermatten, Leonel Pipa Ganzedo and Martin Gómez, winning its first championship before 3,000 followers. Its defender, Marcelo Roca, was selected the 2007 Premier League Most Valuable Player. While seeking for a definitive home stadium, Fabrizi visited Ponce, choosing it over the other municipalities. He subsequently had meeting with Ponce's incumbent mayor, Francisco Zayas Seijo, reaching an agreement to play there.
