Known for their large fan base and record 24 national men's volleyball championships, the Changos de Naranjito are the winningest sports franchise in Puerto Rico.

This rivalry has been labeled as "El Duelo de la Montana", because of their historical battles throughout the years and geographical proximity.

In 1911, Reverend Howard T. Jason arrived in Naranjito to preach for the Presbyterian Church, finding resistance in this devoutly Catholic town.

Reverend Jason took the opportunity to approach and share with the town's youth as well, helping the professors teach the game's rules, subsequently making friendships.

Jason would create tournaments between teams both in Naranjito and in Corozal, which fueled a rivalry between both towns that lives to this day.
