CoachJD are you saying that you wouldn't want your batters to make an adjustment and swing, knowing the Umpire was calling particular pitches strikes that in another game might not be? And the consequence could be striking out looking sometimes... that sounds like striking out just because you disagree with the umpires range of Strike Zone area.
I am in the camp of pay attention to the umpire strike zone.
Batter needs to make adjustments being in the box, which includes not strike out looking.
I think doing anything based on the small sample size of a few calls in a particular game is usually foolish. Just because an umpire called one or two pitches off the corner (you know, maybe, or maybe they were strikes and one coach or whatever thinks they aren't) doesn't mean the whole game will be called that way. I think you need to have an umpire multiple times to even get a general sense of if their zone is somehow different. So swinging at a ball because the umpire called that "same pitch" (was it really?) a strike once before is not only teaching bad habits, it's probably a bad idea in that moment, too.
I also took the OP literally. I don't want to teach young players to swing at pitches over their heads. They're probably not hittable in the first place, and I have no interest in teaching them something bad that's going to hurt them later because they might get a couple 10u hits off 30 mph pitching. Plus, the more you swing at bad pitches, the more you're going to make weak contact and hit into outs anyway. The lazy pop out to the pitcher is not helping the team any more than the strike out looking.
Give me a player with a great eye who doesn't overexpand the strike zone any day. I'll live with the occasional bad call strike out because she's much more often going to only swing at good, hittable pitches and she's going to draw a lot of walks.
Even at a beginner level swinging is reps!
Learning to not swing at trash is also "reps."
