Biography"The Southern League was a Minor League Baseball league that operated in the Southern United States from 1964 to 2020. Along with the Eastern League and Texas League, it was one of three circuits playing at the Double-A level, which is two grades below Major League Baseball. Its headquarters were in the Atlanta suburb of Marietta, Georgia. The league was replaced by Double-A South. The league traces its roots to the original Southern League (1885–1899), the Southern Association (1901–1961), and the original South Atlantic League (1904–1963). The later circuit was renamed the Southern League in 1964, and the league elected to maintain records from that season onward." -- Wikipedia
