The 14th Cuban National Series was won by Agricultores, a team from Havana, who finished just one game ahead of two other teams. The short season of 39 games coincided with the first Selective Series, a sort of domestic all-star league for Cuban baseball players. While the size of the league (14 teams) remained the same as during the prior season, half of the teams in the league changed.
