MLB Signs on to In-Game Usage of Wearable Pitch-Calling Devices

On Tuesday, ESPN’s Buster Olney reported that Major League Baseball is expected to allow players to use wearable signal devices to call pitches this season. Later in the day, the Associated Press reported that the league did indeed approve the use of such devices and sent a five-page memorandum to teams’ general managers, assistant GMs, managers and equipment managers outlining the rules regarding such devices. Known as the PitchCom system, the devices were tested in the minors last season and have made their way around the majors during this year’s spring training, drawing glowing reviews. Aimed at improving the pace of play and countering sign stealing — by both legal and illegal means — their adoption addresses two issues that have been hot-buttons in recent years and have resurfaced this spring. In that light, the league could be doing more to reassure the public that it’s on top of potential abuses of the system.
Created by a company called ProMystic that provides modular technology to mentalists and magicians (!), the PitchCom system consists of a push-button transmitter that fits into a wristband worn by the catcher, and receivers that fit into the padding of the catcher’s helmet and the sweatbands of the caps worn by the pitcher and other fielders. In the transmitter’s nine-button grid, each button corresponds to a given pitch type as well as a location, the latter akin to the familiar three-by-three strike zone grid. From the AP report: “four seam high inside, curve hi middle, slider hi outside, change mid inside, sinker middle, cutter mid out, splitter low inside, knuckle lo middle, two seam low outside.” The other three buttons to the left of the grid are to cancel the selection and to adjust the volume up or down.
Through an encrypted signal, the choice of pitch and location is conveyed, with an audio output that uses a proprietary variant of bone-conduction technology (bypassing the ear canal) and has preprogrammed English and Spanish options, though players can record their own audio. Olney reported that as many as three teammates besides the battery will be allowed to wear receivers so as to aid defensive positioning; generally those will be the middle infielders and the center fielder.
