The Almendares club was one of the oldest and most distinguished baseball teams in the old Cuban League, which existed from 1878 to 1961. Almendares represented the Almendares District on the outskirts of the old city of Havana—when the league was founded it was still considered a suburban area, but later became a district within the enlarged city. Almendares was one of the most successful franchises in the Cuban League. In their early history they were known by their colors as the Blues; later they adopted the name of Alacranes (Scorpions). Throughout their existence they had a famous rivalry with the Habana baseball club.
Baseball in Cuba was more than a sport; it became part of Cuba’s national identity. As baseball grew in the United States, its popularity also grew in Cuba. Cubans living in the U.S. learned and loved baseball, and realized it would be important for their country to have this sport for national unity. For Cubans, baseball offered the possibility of national integration of all Cubans, of all classes, black and white, young and old, men and women. Baseball also offered the Cubans something new to do, a new source of membership, an opportunity participate in something that was perceived to be distinctly Cuban. Cuba had successful baseball teams and players, which tended to unify the country. The Cuban people took great pride in their success in baseball.
After a period of intramural play, professional teams were established. The Cuban League was founded in 1878, two years after the birth of the National League in the U.S. The original three professional clubs were the Habana, Matanzas, and Almendares. Teams were named for their areas.
Almendares won its first championship in 1893–94, carried by pitching ace Juan Manuel Pastoriza, the first of many good club pitchers. One thing that made the Almendares Baseball Club so successful is that it built its team around pitching rather than hitting. Almendares had many successful pitchers, including José Méndez and Adolfo Luque.
Almendares was the first Cuban team to play against a United States team, an 1881 game in Cuba, against the Bitter Hops Baseball Club. Throughout its existence Almendares had a rivalry with Habana. This rivalry started at the beginning of professional league play and lasted until the end. The club even had its own newspaper and magazine, called El Almendarista. These publications grew in popularity almost as fast as new teams started. In 1886 baseball in Cuba was drawing record crowds. A championship game between Habana and Almendares had more than 6,000 fans attending.
