It won't be applauded by me. Simply have the electronic system make the calls and that is the final decision.
This is a good thing. An umpire behind home plate still has plenty to do. Among other things: ruling on HBP, catcher's interference, clock violations, check swings, safe/out calls, balks, fair/foul calls. There's more as well. Less useful ≠ useless. If anything, removing pitch calling from the home plate umpire's duties makes it easier for the umpire to correctly rule on everything else.
I can hardly believe a baseball writer would say this. The catcher has always been and still will be the most important defensive player on the field.
Nope. The electronic system makes a quick correct decision every time, better than any human can do. The call is final, no challenge needed and no delays.
