History
editClass A was originally the highest level ofMinor League Baseball,beginning with the earliest classifications, established circa 1890.[2]: 15 Teams within leagues at this level had their players' contracts protected and the players were subject toreserve clauses.[2]: 15 When the National Association of Professional Baseball Leagues – the formal name of Minor League Baseball – was founded in 1901, Class A remained the highest level, restricted to leagues with cities that had an aggregate population of over a million people.[3][4][5]Entering the 1902 season, the only Class A leagues were theEastern Leagueand theWestern League—both leagues had eight teams, in cities such asToronto, Ontario;Buffalo, New York;Worcester, Massachusetts;Omaha, Nebraska;Denver, Colorado;andPeoria, Illinois.[2]: 187 Leagues operating within less populated areas were classified as Class B, Class C, or Class D.
Class A remained the top classification untilClass AAwas established in 1912, then remained the second-highest classification until Class A1 was established in 1936. In 1946, the top two levels changed from being Class AA and Class A1 to beingClass AAAand AA, with Class A remaining the third-highest level, above Classes B through D. Class A in 1946 consisted of theEastern Leagueand the originalSouth Atlantic League(or "Sally League" ), with teams in communities such asVancouver, British Columbia;Omaha, Nebraska;Colorado Springs, Colorado;Charlotte, North Carolina;Scranton, Pennsylvania;andAllentown, Pennsylvania.Class A soon included theWestern League(1947–1958),Central League(1948–1951) andWestern International League(1952–1954). The Western International League became the Class BNorthwest Leaguein 1955, and the Western and Central loops folded.
The hierarchy of Triple-A through Class D continued until Minor League Baseball restructured in 1963, at which time Classes B through D were abolished, with existing leagues at those levels reassigned into Class A, while the South Atlantic League (renamed as theSouthern League) and Eastern League ascended to Double-A.
In 1965, aClass A Short Seasondesignation was created, for teams playing June–September schedules, primarily meant for new players acquired via theamateur draft.TheClass A-Advanceddesignation was established in 1990, between Class A and Double-A in the minor league hierarchy.[6]Class A and Class A Short Season were considered independent classifications, with Class A having "Full-Season" and Advanced sub-classifications, per the rules governing baseball's minor leagues.[7]The overall hierarchy was:
- Triple-A
- Double-A
- Class A-Advanced
- Class A ( "Full-Season A" )
- Class A Short Season ( "Short-Season A" )
- Rookie league
Entering the 2020 minor league season (which was not played due to theCOVID-19 pandemic), Class A consisted of theMidwest LeagueandSouth Atlantic League(a newer "Sally League", which been formed in 1963 as theWestern Carolinas League). Prior to the 2021 season, MLB restructured the minor leagues, eliminating Class A Short Season and discontinuing the use of all historical league names within Minor League Baseball.[8]The Midwest League and South Atlantic League were reclassified as "High-A" leagues, and operated during 2021 asHigh-A CentralandHigh-A East,respectively. They were replaced at the Class A level by three "Low-A" leagues:[9]Low-A West,Low-A East,andLow-A Southeast.[10]These leagues had historically been known as theCalifornia League,Carolina League,andFlorida State League,respectively, and had previously operated at the Class A-Advanced level.[8]These three leagues operated with Low-A naming for the 2021 season. Following MLB's acquisition of the rights to the names of the historical minor leagues, MLB announced on March 16, 2022, that the leagues would revert to their prior names, effective with the 2022 season.[11]MLB also discontinued use of "Low-A" in favor of Single-A.[11]
