I have been a parent in two teams now (I’ve volunteered to assist with this second team) where I have had the coaches and a couple of parents that swear by the idea of changing pitchers just to “mess up” the other batters. I don’t get it. Unless you’re changing mid-at bat, it can’t seem to matter much from trip through the lineup 1 with pitcher A and trip through the lineup 2 with pitcher B or am I completely missing something here? I have seen coaches pull pitchers, that are killing it, solely based on this idea. For reference I’m talking about 12U B level ball. My question is, am I missing something or are the coaches that believe in this wrong/overestimating what this does to batters?
