Major League Baseball issued a crackdown on the use of artificial intelligence for in-game decisions, banning the practice effective Wednesday. The directive, communicated in a June 11 memo, was implemented the day before the second half of the season commenced after the All-Star break.

Sources indicated that several teams, including the New York Mets, had been utilizing league-issued iPads in dugouts for purposes beyond their intended scope. This reportedly included leveraging artificial intelligence for recommendations on substitutions, pitch calling, and other strategic choices typically made by players and coaches. The memo, sent by MLB executive vice president of baseball operations Morgan Sword, was addressed to general managers, assistant GMs, and video coordinators.

While iPads will remain permitted in dugouts, their functionality has been restricted. Previously, custom tabs allowed teams to access other programs and utilize AI-driven insights. These capabilities have now been disabled. The tablets continue to provide access to league-provided Statcast information, multiple video angles, and data related to the automated ball-strike system. However, video accessed during games is only available on a delay.

This shift is anticipated to impact teams that have increasingly relied on analytics and adopted dugout-based pitch calling strategies, a trend that has become more prevalent this season. The league's decision acknowledges the growing influence of data analysis across all facets of the game.

MLB has allowed the use of iPads in dugouts for over a decade. A review conducted earlier this year found teams to be compliant with existing rules regarding sign-stealing and electronic device usage, meaning no penalties were issued. Teams were granted approximately one month to cease using AI for in-game decision-making to allow for necessary adjustments. The league's move underscores a broader conversation about the integration of technology and artificial intelligence in professional sports.
