Do you believe in one swing that covers the strike zone? Or do you believe there are adjustments made for pitch location?
Agreed, 1 swing, let tilt and posture dictate pitch location.One swing will cover the strike zone. Yes, for sure. Of course, you may tilt your spine up or down for extreme high/low.
The biggest problem is when people try to change their swing for down/out locations. If you have ever used a hitting stick, you will quickly realize that the forearms and the bat are plenty long enough to reach any pitch at the far down/out corner of the strike zone.
Almost everyone tries to throw their back elbow away from the body, and even bend their knees for outside and down pitches. A hitting stick will prove this to even 6 yr olds in a few swings.
Now, of course, some people think they need a new swing for neck-high pitches. And they waste time swinging. Their problem is they need to NOT swing at all (I'm looking at all you riseball swing-and-missers).
