When Esteban Bellán left St. John’s College in 1868 to pursue a career in baseball (with the Unions of Morrisania) he was not the only Cuban to do so.
Rafael de la Rúa, a native of Matanzas, Cuba, played 12 games for the Unions of Lansingburgh of the National Association in that same year of 1868. He was a pitcher, with a good screwball but some control problems.
De la Rúa joins Bellán as the first Latin player in an organized and highly competitive league. The National Association would not be considered a Major League until it became professional in 1871, and still that is debatable. But what is clear is that they are the first Latin ballplayers to compete at the highest level of baseball in the United States.
