I'm waiting to hear DO-OVER's take on the cues. TJ
Sorry, I've been away.
I tend to keep things very simple. Quite the opposite of FFS, which is not a shot at him. I don't invent drills/concepts. I let others do that and soak out all the knowledge I can from them.
What I previously posted above is a what I've gleaned those who have helped us in the past.
With regard to combating over rotating the upper body, here are the cues I used:
"Tilt not turn" is a move to keep the hands/arms/shoulders in the "alley" as my DD refers to it, or the slot as I refer to it, that exists directly in front of the hitter and is as square to the plate, or "hitting alley" as we call it, as possible for as long as possible. We use terms SHE chooses and understands. The cue I first used to my DD was "keep
you hands looking at the pitcher for the whole swing. She was 15yo at the time an easily understood this cue. Compare Miggy, Trout, Donalson . . . to the girl in the clip
in this thread. They aren't close to be in line with each other. That's not saying this girl has a crappy swing. I'm saying I would remove the shoulder turn in the load.
Search this site for Donny's complete presentation fir his PDF instruction if you already don't have it. It was my toilet primer for years (if you know what I'm saying).
It isn't easy to rid the hitter of this shoulder action. Over rotation of the shoulders is intuitive so it takes a lot of corrective swings.
Look at the best hitters of today in MLB. They have different shoulder/arms/hands action as well as how they use the lower half. Look at the clip of Chamberlin taking indoor batting practice. Watch her leg usage (not necessarily her stride.) You'll also note an arm bar in her swing. I wouldn't recommend it, but it works for her.
I can't view clips hear at work anymore, and I'm not supposed be on the web engaging in non-work related stuff, but I'm fairly sure she is square for along time.
Sorry to ramble on.
