I do have an issue with the auto-pinch running Perkins for Vaughn thing. If the Brewers have the lead and the defensive move is inevitable, fine. But if we are tied, I don't think we are playing the correct percentages - especially in a non-steal situation. At least not initially.
Perkins for Vaughn from 1st increases the chances of scoring on a double by a good margin - but the chances of a double being hit are low single digits? So the amount of doubles Perkins will score on compared to Vaughn PLUS the low chance a double is hit is probably something like a 1-2%ish chance of the move being necessary?
Now if Vaughn reaches 2nd, I am ok with the pinch runner because scoring from a single AND the likelihood of a single being hit are much higher probabilities. I also understand going 1st to 3rd, etc.
I can't say for certain if PR Perkins for Vaughn immediately like they are doing has produced the necessary result to make it the right move yet this year. But we now have a data point (tonight) where pinch running him did not alter us scoring, did not alter the defense the following inning, and DID take an at bat away from Vaughn with a chance to win the game later.
Sorry, that is a lot of typing. Main point, let the situation breathe a little before auto pulling Vaughn in those spots. We have more options than we think? Am I wrong?
