They were first introduced in dugouts in 2016, but after the Astros’ sign-stealing scandal in 2017, the iPads were more tightly regulated. Teams were unable to install any new apps, access the internet or have outside communication. They were strictly for reviewing video and data — on a delay. But, as Eno Sarris reports …“Over time, players and teams have pushed for a loosening of some restrictions surrounding the iPads. Coaches and players wanted the ability to customize what the tablets could do for them, and the league allowed these liberties.”Any parent of a teenager could have predicted what came next.“(Teams began using the iPads) beyond their originally intended purpose to include recommendations regarding substitutions, pitch calling and other in-game decisions traditionally made by players and coaches.”So the practice has now been officially banned. Teams have a new strict list of what data is and is not allowed on the iPad … and strictly no AI. (The Pioneer League Oakland Ballers are obviously exempt.)I think this all casts a new light on the increasingly popular practice of calling pitches from the dugout, doesn’t it?More on this: The “Rates & Barrels” crew talk about MLB’s ban in their latest episode.Middle ReliefThis week’s Sliders column starts with Tyler Kepner reporting on Ken Griffey Jr.’s involvement in the Swingman Classic, an annual showcase game that highlights the top NCAA baseball players from HBCUs.
