In 2022, Major League Baseball first allowed PitchCom, a system that allows a catcher to call signs by pressing a button on a transponder attached to his arm or shinguard.The signal is relayed to the pitcher via a microphone stored in his cap above his ear, so the pitcher can audibly hear what pitch the catcher is calling.
