Drills to fix hand and bat angle at launch position?
My son has developed a really bad habit of laying his bat down behind his head during his load and stride into launch position where the barrel ends up basically behind his front shoulder and the knob is pointed at the umpire's head. His load, coil, stride, swing are pretty good but he tends to be late on pitches due to his long swing from behind his front shoulder.
What drills can we do to break this habit? We've been doing a load, pause, stride, pause drill to make sure he is in the correct launch position before he swings on the tee but it all breaks down once we get into live pitching. is it just a reps thing?
