In an effort to cut down on sign-stealing, MLB instituted the PitchCom as an option for teams in 2022. The system allows the pitcher and catcher to communicate calls through an earpiece and wristband — rather than the catcher showing fingers to call pitches.
Like anything with technology, the system isn’t perfect. It malfunctions on occasion, and some pitchers have even claimed to have PitchCom issues just to buy some extra time in the pitch-clock era.
