i am OK with keeping mouth shut (allright, not really OK, but I can do it). issue is that she is not going to get any other feedback to pull her back from bad mechanics. the HC is great at trying to get her to relax, have fun, etc., but DD still reaches for the strike zone.
at this stage in her development she simply is not aware enough of what she is doing/not doing. she just is focused on trying to throw strikes, which leads to reaching for the zone. last game, she basically went 4 innings like that, hit about 6 batters, about 20BB, i never said a word, and the more she reached for zone, worse it got. even if we send her to lessons, instructor is unlikely to be at games, she needs to figure out someway to receive/accept feedback. otherwise her circle time is going to drop to nearly nothing.
