Verified Timeline
Lore & Background
Prior to 1946, Double-A was the highest level of play in the minor leagues. Additional classifications were A through D, each of which was used by the Red Sox. Class A1 was created in 1936 and existed through 1945, and was also used by the Red Sox for several seasons. One Class E league existed in 1943, but was not used by the Red Sox. From 1946 to 1962, the minors operated with six classes (Triple-A, Double-A, and Classes A, B, C, and D). The Pacific Coast League (PCL) was reclassified from Triple-A to Open in 1952 due to the possibility of becoming a third major league. This arrangement ended following the 1957 season when the relocation of the National League's Dodgers and Giants to the West Coast ended any chance of the PCL being promoted.
In Their Own Story
The foundation of the minors' current structure was the result of a reorganization initiated by Major League Baseball (MLB) before the 1963 season. The reduction from six classes to four (Triple-A, Double-AA, Class A, and Rookie) was a response to the general decline of the minors throughout the 1950s and early-1960s when leagues and teams folded due to shrinking attendance caused by baseball fans' preference for staying at home to watch MLB games on television. The 1963 reorganization resulted in the Eastern and South Atlantic Leagues being elevated from Class A to Double-A, five of seven Class D circuits plus the ones in B and C upgraded to A, and the Appalachian League reclassified from D to Rookie. The only change made within the next 27 years was some Class A teams adopting 'Short Season' schedules starting in 1965.
Reader's Guide
Minor League Baseball operated with six classes from 1990 to 2020. The Class A level was subdivided for a second time with the creation of Class A-Advanced. The Rookie level consisted of domestic and foreign circuits. During several seasons, the Red Sox fielded two teams in the Dominican Summer League (DSL). Prior to the 2021 season, Major League Baseball reorganized Minor League Baseball; changes included ending the Class A Short Season classification, and limiting each major league team to four affiliates above the Rookie level. Additionally, the composition and names of leagues above the Rookie level were changed. For the Red Sox' farm system: The Worcester Red Sox succeeded the Pawtucket Red Sox as the Triple-A affiliate. The Lowell Spinners, who had been a Class A Short Season team, were dropped as an affiliate. The Greenville Drive and Salem Red Sox swapped relative classification levels, with Greenville moving from Single-A to 'High-A', and Salem moving from Class A-Advanced to 'Low-A'. Low-A was reclassified as Single-A in 2022.
