In the wake of Major League Baseball's decision to reclassify the Negro Leagues as majors, the Society for American Baseball Research has recommended seven different leagues for the status.
Per the Associated Press (via ESPN.com), SABR announced Thursday it is recommending big league status for "Negro National League I (1920-31), Negro National League II (1933-48), Negro American League (1937-48), Eastern Colored League (1923-28), American Negro League (1929), East-West League (1932) and Negro Southern League (1932)."
MLB officially announced in December that Negro Leagues from the period of 1920-48 will be elevated to Major League status.
