Since the beginning of baseball in the 19th century, catchers had used their fingers to signal the type of pitch and its intended location. “It basically eliminates all need to create a sign system, for a catcher giving signs,” MLB chief operations and strategy officer Chris Marinak said Tuesday. MLB is providing each team with three transmitters, 10 receivers and a charging case for the PitchCom Pitcher Catcher Communication Device. Pitch clocks will be used at all minor league stadiums, likely a prelude to their installation at big league ballparks for 2023. Marinak said that fans using the MLB Ballpark app to enter stadiums with electronic tickets rose from 3% in 2017 to 19% in 2019 to 56% in 2021.
