@ jtat I will clarify if that helps you
I teach my pitchers if we are going to miss, miss in the direction we are throwing, I also teach a hard snap on every pitch so that in the event a ball floats over the middle if its spun hard enough it will get driven into the ground or if its a rise ball into the air keeping the pitcher safe
At the YOUNG ages pitchers (in general) are going to miss the corners and throw up the middle enough without a coach directing them to throw up the middle because most lack control and a hard tight spin that comes with age....My pitchers did not have any come-backers that game or at all as far as I know, But then again, I also teach my girls to ignore a coach that directs them to throw up the middle to begin with, not that it would have mattered she was pulled for walking batters anyway,lol!!
