Major League Baseball just drew a hard line on algorithmic coaching. Starting Wednesday night—when the second half of the season kicked off—MLB restricted access to custom tabs on dugout iPads that teams had been using for AI-assisted in-game decision-making. The league's move targets programs that were generating recommendations for substitutions, pitch calling, and other strategic choices traditionally left to players and coaches.

The Memo That Set Things Off

The crackdown stems from a June 11 memo penned by MLB executive vice president Morgan Sword and addressed to general managers, assistant GMs, and video coordinators. A review by the competition committee found clubs technically compliant with existing regulations—but that compliance window is now closing fast. "Instituting this prohibition beginning with the second half of the season is intended to provide clubs that have relied on the custom tab with appropriate lead-time to make any necessary adjustments," Sword wrote in the memo, first reported by The Athletic and obtained by the Associated Press.

What Teams Were Actually Running

Here's where it gets interesting from a tech perspective. The dugout iPads—part of a program that started as a pilot late in 2015 and expanded under an Apple partnership in 2016—provided teams with video feeds and league-supplied data. But the custom tab gave franchises room to run third-party code, and some clubs apparently built or deployed systems generating real-time strategic recommendations during games. That's not quite autonomous AI calling pitches, but it's damn close to having a statistical co-pilot whispering in your ear from the bench.

The Long Road Here

MLB's relationship with technology in dugouts has been rocky. Video access was eliminated entirely during the 2020 COVID-shortened season—a direct fallout from the Houston Astros sign-stealing scandal that had rocked the sport years earlier. When video returned in 2021, it came with restrictions. Now those restrictions are tightening further as the league grapples with where human judgment ends and machine-assisted strategy begins.

Key Takeaways

  • Custom tabs on league-issued iPads have been disabled effective immediately for the second half of the season
  • Teams had been using these tools for substitution recommendations, pitch selection, and other in-game calls
  • The move comes after a competition committee review found existing rules were being stretched by AI-powered programs

The Bottom Line

This is MLB playing catch-up with a technology arms race that probably got ahead of them faster than anyone expected. Good. Let humans manage the human game. But let's be real—the teams with the most sophisticated data operations just lost their edge, and someone's going to find a workaround before Opening Day 2027 rolls around. They always do.
