Since 2022, the National Series has been supplanted as the island's top division by the Cuban Elite League.
Early organized Cuban baseball was dominated by teams from the Havana metropolitan area.
[1] The most successful teams were Club Habana (which won a record 30 championships, including the first tournament in 1879) and Almendares.
In the modern-era of Cuban baseball, starting with the establishment of the National Series in 1961, teams from other parts of the country have enjoyed more success, although Industriales of Havana still hold the most titles (12).
For the entire history of the Cuban League and National Series up to 1985, the champion was determined by win-loss record.
