Major League Baseball has effectively barred teams from using artificial intelligence tools on dugout iPads during games to influence tactical decisions. The move matters because clubs had begun using bespoke applications that could shape real-time choices traditionally made by players and coaching staff.

The applications reportedly offered recommendations on substitutions, pitch calling and other in-game decisions, extending iPads beyond their original intended use. MLB’s action draws a clearer line around technology in the dugout while allowing the sport to retain human control over live game strategy.
