I don't agree with the premise that pitch tipping and sign stealing are rare phenomena. Both have been part of the game since the beginning but if this offseason taught us anything its that sign stealing is rampant. We all know the reduction in mound visits was because they got out of hand due to fear of sign stealing.Because pitch tipping and sign stealing are both rare phenomena, and the change we're looking at is massive. I'm not sure exactly how rare pitch tipping is, but I am quite sure that the absence of in-game pitch tipping using video — again, pre-game video scouting is still allowed! — is not enough to turn a .774 OPS hitter into a .344 OPS hitter.
I maintain that baseball has made the wrong decisions here and a wireless transmitter amongst players on the same team needs to be introduced as a means of conveying your own team's signs.
Limiting access to the video room is the wrong move.
As for your other analysis, I don't disagree with it. I just wanted to make sure that pitch tipping and sign stealing weren't dismissed outright.
