MLB informed clubs in a memo today that it is moving forward with regular-season use of PitchCom -- a wearable device that transmits signals from catcher to pitcher -- in 2022. The technology, which will be optional, was approved by the MLB Players Association after receiving generally positive feedback in experimental usage at the Single-A level last year and in big league camps during Spring Training this year.
Aimed at both improving pace of play and preventing opponent sign-stealing, PitchCom eliminates the need for a catcher’s traditional finger signals. Rather, the catcher wears a forearm sleeve -- resembling a remote control -- with nine buttons for calling the pitch and location. The pitcher has a receiver in his cap, the catcher has one in his helmet and receivers can also be worn by up to three other fielders (typically, the two middle infielders and the center fielder) to adjust fielder positioning.
