93 Cubs minor leaguers will be reporting to the Cubs Under Armour Performance Center at Mesa Riverview Park over the next few days.
68 of the players will be assigned to the "basic" (traditional) Cubs AZ Instructional League squad, 19 will be assigned to the "advanced" instructs squad, and eight will be assigned to the Mesa Solar Sox in the Arizona Fall League. (Two of the players assigned to the Cubs "advanced" instructs squad will move to the AFL on 10/4).
Only the "advanced" squad (actually a Cubs/Angels "co-op" team) will be playing games against other organizations.
