MLB Bans AI-Powered Apps On Dugout iPads, Effective This Week

Major League Baseball has shut the door on artificial intelligence creeping into in-game decision-making. A commissioner's office memo issued June 11 laid out new restrictions on dugout iPads, and the ban took full effect Wednesday, July 15, as teams resumed play after the All-Star break, according to a memo obtained by Fox News Digital.

The problem, according to the league's review, was some clubs installing custom apps that went well beyond scouting reports and video replay. Those apps were being used, in the league's words, for "recommendations regarding substitutions, pitch calling and other in-game decisions traditionally made by players and coaches."

As many as one-third of MLB teams were using the iPads outside their intended purpose, according to reporting from The Athletic, which first broke the story on the restrictions.

How the iPads actually work

MLB-issued dugout iPads have three tabs. One holds Statcast data and multiple video angles provided directly by the league. Another covers information tied to the automated ball-strike system, the tech MLB has been testing to assist home plate umpires. The third tab was open territory, where individual teams built their own custom apps.

That third tab is now off-limits. The league is not banning data or video access outright. It is banning the layer where teams had started plugging in AI tools to spit out real-time suggestions on pitching changes, defensive shifts and substitutions, decisions that have always belonged to managers and coaches, not algorithms.

No cheating found, but a preemptive move

MLB's review found no team broke existing rules on sign stealing or electronic-device usage. This wasn't a scandal being punished. It was the league getting ahead of one.

"Gotta stop the cheating before there's cheating now," one front office executive told The Athletic, a line that captures the preventive spirit of the memo. The league also tightened related rules: in-game video is only available on a delay, and clubhouse postings now bar non-field personnel from entering the dugout during games.

The case for letting AI stay in the game

There's a fair argument on the other side, and it deserves a straight hearing. Front offices have used data analytics for two decades to make baseball smarter, from launch angles to defensive positioning. Teams could reasonably argue that AI is just the next iteration of the same trend, and that if a $30 million analytics department can build models before a game, why not let a tablet crunch the same numbers between innings?

That argument has some merit in principle. But baseball has always drawn a line between analysis done ahead of time and decisions made live, in real time, by the uniformed personnel on the field. An AI tool feeding a manager a pitching-change recommendation mid-inning blurs that line in a way pre-game scouting reports never did. It also raises a practical fairness question: teams with the deepest pockets and best engineers could build superior in-game AI, turning a strategy edge into an arms race that has nothing to do with players' skill on the field.

What changes on the field

Practically, nothing about pitch calling or double switches changes for fans watching from the stands. Managers and coaches still make the calls. What's gone is the black box of a custom-built AI app whispering suggestions from the bench.

MLB's move puts it ahead of other leagues still wrestling with how deep AI should go into competitive strategy. The NFL and NBA have their own replay and analytics systems, but neither has issued a comparable memo explicitly targeting AI-driven, real-time decision support.

The open question is enforcement. The memo bans the practice, but it doesn't detail specific penalties for violations going forward, and it's unclear how the league plans to audit what teams build into that third tab now that it's supposedly locked down. Given that roughly a third of teams were already testing the limits before the ban, per The Athletic's reporting, MLB will need a real verification process, not just a memo, if it wants the rule to stick.
