ThePhiladelphia Philliesfarm system consists of sevenMinor League Baseball affiliates across theUnited States and in theDominican Republic. Five teams are owned by the major league club, while two—theLehigh Valley IronPigs andJersey Shore BlueClaws—are independently owned.

On April 14, 1934, the Phillies entered into their first affiliation agreement with theNew York–Penn LeagueHazleton Mountaineers.^[1] The Phillies have been affiliated with theHigh-A Jersey Shore BlueClaws of theSouth Atlantic League since 2001, making it the longest-running active affiliation in the organization among teams not owned by the Phillies.^[2] Their newest affiliate is theLehigh Valley IronPigs of theInternational League, which became the Phillies'Triple-A club in 2008.^[2]

Minor League Baseball operated with five classes (Double-A,Class A,Class B,Class C, andClass D) from 1934 to 1935.^[4]Class A1, between Double-A and Class A, was added in 1936.^[5] The minors continued to operate with these six levels through 1945.^[5]Triple-A was established as the highest classification in 1946, and Class A1 became Double-A, with Class A through D remaining.^[5] These six levels continued through 1962.^[4] ThePacific 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 theNational League'sDodgers andGiants to theWest Coast ended any chance of the PCL being promoted.^[4]

Prior to the 1963 season,Major League Baseball (MLB) initiated a reorganization of Minor League Baseball that resulted in a reduction from six classes to four (Triple-A, Double-A, Class A, andRookie) in 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 only change made within the next 27 years was Class A being subdivided for the first time to formClass A Short Season in 1966.^[4]

Minor League Baseball operated with six classes from 1990 to 2020. In 1990, the Class A level was subdivided for a second time with the creation ofClass A-Advanced. The Rookie level consisted of domestic and foreign circuits.^[4]

The current structure of Minor League Baseball is the result of an overall contraction of the system beginning with the 2021 season. Class A was reduced to two levels:High-A andLow-A.^[95] Low-A was reclassified as Single-A in 2022.^[96]
