I have no problem with base coaches positioning themselves behind the box, on the home plate side of the box, or on the outfield side of the box. They can even be more than a step or two away. And there is nothing that says that they can't come down the line to wave in a runner chuggin' for home. But I'm not about to let any coach come across those foul lines while the ball is still in play, or without my permission. This coach could have hollered at the batter from where he was. Running out onto the field was illegal and unnecessary. Therefore, I
might (my decision, my right) jack this yahoo. Depending on the exact circumstances, I may just yell at him to get his posterior back in his box.
