Admiring a HR in the box is violating an unwritten rule. As is walking across the mound after making an out. As is bunting to break up a no hitter.It’s a kids game and they broke an unwritten rule.
Actively using technology to tip pitches to the batter is a huge violation of the rules.
If the *'s figured out the pitch signs by having a dude on 2nd seeing what the catcher was throwing down and he relayed that to the batter in real time - I have zero issue with it. That's gamemanship.
But don't sugarcoat the situation. They fucking cheated and they benefited from it - otherwise why would they do it?
