Followup to interference/deception

Question
Thanks for the previous answer.  Is there also no penalty for the runner who runs to first with only two strikes to draw the throw.  Seems like making a "travesty of the game."  Also, the opposing coach could not yell "swing" to an opposing player or  "mine" to a defender could they.

Answer
I think that repeated instances of all of these would draw a warning from the umpire.  If they continued, a coach could be ejected.  One way to keep the coaches in the game and put some teeth in the warning would be to make the warning something like;  "Coach this is your warning, if that behaviour continues either you will be ejected or your pitcher's stike zone will be the size of a shoebox!"
