what difference would a buzzer make?
I mean ‘hit the ball’ seems obvious.
For that matter I’ve never understood ‘signals’... ‘run to the next base’ seems obvious too...
what am I not getting?
Signals whether it’s going to be a curve, slider, low, etc.
Probably a combination of buzzes.
I'm not sure what you are asking. The buzzer would directly communicate to the hitter what pitch was coming. This is a huge unfair advantage. Part of the problem with stealing signs and it actually giving an advantage is getting the information to the hitter quickly. When you introduce electronics like a buzzer you may as well have a headset in the batting helmet. With a buzzer there is little chance of miscommunication and the hitter would receive the information with plenty of time to prepare. It's cheating on a level that IMO would be considered fraud.
does that make sense?
I will add, if you are not a baseball fan that the deception of pitches is one of the main tools the pitcher has in his favor. The best hitters in baseball can only get a base hit about one out of 3 times to the plate. Now let the hitter know positively in advance what pitch is coming and those odds would change dramatically.
It changes the dynamics of the guessing game to "can I hit this pitcher on this pitch" which can easily and just as quickly turn into, "I'm 1M in debt to a bookie and if I screw up this game enough where the bookie makes his spread, I'm out of my debt." - aka throwing baseball games, just like the Black Sox scandal a century ago.
It gives the hitter a distinct advantage at the plate, knowing what is coming - and when to swing and when to hold off.
