The Arizona Complex League (ACL) is a rookie-level Minor League Baseball league that operates in and around Phoenix, Arizona, since 1988. Prior to 2021, it was known as the Arizona League (AZL). Along with the Florida Complex League (FCL), it forms the lowest rung on the North American minor-league ladder.
ACL teams play at the minor league spring training complexes of their parent Major League Baseball (MLB) clubs and are owned by those parent clubs. Admission is not charged and no concessions are operated at the teams' games. Every Cactus League team fields at least one team in the league. Night games are commonly played in the spring training stadium, although games may also be played at the team's practice fields.
As of the 2021 season, there is no league limit to how many players can be on an active roster, but no team can have more than three players with four or more years of minor-league experience.[1] Major-league players on rehabilitation assignments may also appear in the league.
