Puerto Rico currently has the fourth-most active players in Major League Baseball (MLB) among Latin American jurisdictions, behind the Dominican Republic, Venezuela and Cuba.[1] More than three hundred players from the archipelago have played in the major leagues since 1926. This includes players who were born in either one of the archipelago's islands and those of Puerto Rican heritage. Only those players who have worked in the major leagues are listed, not those active in the minor leagues, nor negro independent leagues.
For years, it was considered that the first player from Puerto Rico to play in the major leagues was Hiram Bithorn in 1942. But this changed in December 2020, when seven Negro baseball leagues between 1920 and 1948 were recognized as "major leagues." Thus, the first Puerto Rican to play baseball on the major leagues was Jose "Gacho" Torres, who debuted in 1926.
After the baseball color line was abandoned following Jackie Robinson's debut in the National League of MLB, more players from the island signed contracts. This led to an improvement in their performance, and some of them were selected to participate in the Major League Baseball All-Star Game. Including their names in the Major League Baseball draft is a requisite for first-year players born in Puerto Rico, because the league recognizes the island as a jurisdiction within the United States.[2] Following the implementation of this measure, Puerto Rico's government requested exclusion from the draft and help to develop players, in order to reduce the impact of the change in the format of talent development.[2]
