Phillies have come a long way in a short period of time. They got a new skipper mid season this year. I thought I heard that they do not signal the pitcher with hand signals. Some sort of buzzer that is attached to the wrist of the catcher. He signals the pitcher with it. Goes to a earpiece. Never heard of it but swear I heard it mentioned during the last game.
Yeah, it seemed like that was happening during the game. I figured that must be what all the teams are doing now.
Yes, MLB now allows PitchCom electronic communication.
