Minor League Catcher Hits Batter Trying To Throw To 3rd Base

"How can the batter "know" the runner is stealing?"

There is this weird thing that they have started doing in baseball. What they do is: They have a guy, usually a coach, standing on third base. And this guy does the craziest thing, but what he does is he gives hand/body signals to the runners and the batters to tell them to steal/bunt/take any number of things. Its a kinda new thing that they have been working on for a little over 100 years.

And hopefully, someone films it, "again".

It's a dead ball foul.
the pitch does not count and the runner(s) go back to the base where they were at.
Let's do it all over again.

How can the batter "know" the runner is stealing?

Batter probably walked up to the plate and said something like, "How's your wife and my kids?"

I thought the batter had to get out of the way to give the catcher a fair shot. If not, then we'ld see a lot more 3rd steals.

That looked intentional.

The catcher, the hitter is supposed to stand his ground in the batters box. I like how the catcher tried to say the batter was in the wrong

I'm not very familiar with baseball rules. Who messed up?
