Baseball in Puerto Rico
By the 1949-50 season, several new ballparks were built, each containing 6,000 or more seats. The largest new stadium was Ponce's Estadio Francisco Montaner with 9,718 seats. Montaner has the distinction of being the first stadium in Puerto Rico that installed an artificial surface field. The installation of lights, which allowed for night games, further boosted stadium attendances. The Stadium was named to honor Francisco "Paquito" Montaner, one of the greatest Puerto Rican pitchers of all times.
Changos de Naranjito
Known for their large fan base and record 23 national men's volleyball championships, the Changos de Naranjito are the winningest sports franchise in Puerto Rico. Their main rival is the Plataneros de Corozal. This rivalry has been labeled as "El Duelo de la Montana", because of their historical battles throughout the years and geographical proximity. They held a battle for the ages in the 2007 LVSM men's volleyball finals with the Changos defeating Corozal in a 7th game held at the Ruben Rodriguez Coliseum in Bayamón, Puerto Rico.
