Wikipedia - Nicaraguan Professional Baseball League
The Nicaraguan Professional Baseball League (Spanish: Liga de Béisbol Profesional Nacional or LBPN), known as the Campeonato Claro for sponsorship purposes, is the professional baseball league of Nicaragua. The league consists of five teams with a 30-game regular season schedule that runs from November to December, followed by a four team playoff round robin; the two best teams advance to a best of seven championship series.
Inaugurated on March 30, 1956, in Estadio Nacional, the first game was between the teams from San Fernando and Bóer. The Nicaraguan public's excitement for baseball grew as foreign professional teams and foreign players came to play in their country. The teams from Bóer and León were the most successful teams in those years with three championships each. Due to economic difficulties, the league had to shut down in 1967, but professional baseball was re-established in 2004. Since then, Bóer has led the league in championships with five.
