In 1992, the Colorado Rockies and Chicago Cubs fielded a cooperative team in the Arizona League (AZL), known as the Arizona League Rockies/Cubs. The team was then an affiliate of only the Rockies from 1993 to 2000, and named as such.[2] The teams were located in Mesa (1992–1993), Chandler (1994–1997), and Tucson (1998–2000). The team won its first, and to date only, championship in 1998, under manager P. J. Carey.
Prior to the 2021 season, the Arizona League was renamed as the Arizona Complex League (ACL). Also in 2021, the Rockies rookie team returned to Arizona for the first time in 20 years.
