To answer one of my own questions…if I’m remembering right, Chris said in one of his videos (which are great BTW, do more!) that there is no penalty for an incorrect ghost runner, just replace him with the correct one. That’s interesting because while that is what is done with an incorrect batter before a completed at bat, after a completed at bat it gets a lot more serious: the correct batter is out and the play is nullified. But nothing comparable to that with the ghost runner, say if he should score, right?
