The league was formed in an effort to increase the quality of Cuban baseball, to bring it closer to the other professional winter leagues of the Caribbean. Professional baseball was abolished in Cuba in 1961. A desire to bring together the best players from the National Series, as well as address the drain of Cuban talent from the island to more competitive foreign leagues, contributed to the change of format in the league's second season (2023-24).[3]
The 2023-24 LEB champion was invited to the prospective Intercontinental Series, to be held in Barranquilla in 2024, but the league declined the invitation, in part due to the inclusion of FEPCUBE, a team composed of Cuban expatriate and defected players.[5] Pressure from the Cuban government eventually saw that tournament cancelled.[6] Instead, LEB announced that it would take part a tournament labeled the "Copa Antillana" in Puerto Rico; however that tournament never materialized.[7]
In the Elite League's third season, out of the 16 teams that form part of the Cuban National Series, only six of them qualified into the new league. These six teams occupied the top spots in the 2024 Cuban National Series.
In the Elite League's inaugural 2022-23 LEB season, the 16 teams of the Cuban National Series were grouped into six regional teams. However, this format was considered unpopular, and for the league's second season, the decision was made to include National Series teams.[3]
