ACL Angels vs ACL Cubs is a regular-season Arizona Complex League (rookie-level) baseball game played at Sloan Park in Mesa, Arizona. The matchup features the Angels’ and Cubs’ complex squads—largely recent draftees and lower-level prospects—competing as part of the developmental summer circuit that gives young players live-game experience. Games in this league are staged at MLB spring-training facilities across the Phoenix metro area and focus on player development and evaluation within each organization.
