Dusty, I once thought that way until a HS coach explained to me her rationale for it. She said the pitcher in question had a very good drop ball for an out pitch, or weak ground ball out but if it wasn't working she would struggle with pitch count for the game anyway, so if she could find her grove between an inning she would keep her in and it would reduce her overall pitch count in the game, if she couldn't find her grove in between the inning she would go with another pitcher. I watched her do this several times during the season and it seemed like a decent strategy. The pitchers where only pitching 2 maybe 3 games in a week in HS so very little chance of over use compared to what these girls see in TB. If you only have one pitcher then this is probably not a good idea.
