I was at Lowe's tonight. Tomorrow she has Dance class, so we take Thursdays off from pitching. Dad has some "Home Improvements" in the works! Friday she has SB practice (playing in a winter tournament in March and one of the coaches has access to an indoor facility) so I'll try your recommendation on Saturday. I've tried stretching her stride a few times and she really regressed with her speed and the timing went haywire. It just looked like she didn't have the body control, and core strength to be able to maintain the proper motion when she stretched her stride out. She also didn't have the strength in her plant foot to "catch" herself without the knee collapsing which caused her upper body to fall forward, out of balance. That was a couple months ago, so it's a good time to revisit.Whip looks good. Her timing looks pretty good.
Cut a piece of carpet, thin plywood, or whatever works to 6x24", then go the the local home improvement store and buy some non-residue duct tape. Tape your pitching rubber to your floor and use it every time you pitch. The tape is spendy, but worth it.
Her current stride is about 4.5 lengths of her shoe. Try this and ask her what she thinks/feels: Have her step toe/heel 6.5 shoe lengths from the front of your rubber. Take a 6 inch piece of the non-residue tape and lay it on that spot at about a 45 degree angle. Try a few dry pitches (no ball) and see what happens. Add a ball and try a few more. Ask her how it feels. Do this without a target. Preferably into a net, tarp, blanket, old mattress, carpet, etc...
Let me know how it goes.
I had her stretch out to about 6 1/2 shoe lengths tonight. The black line i put on the ground is 6 lengths from the front of the marked off rubber. The 2 lines behind that are her typical stride location on 5 or 6 pitches before I told her what i was even doing. I told her to land at the far mark, assuming the middle of her foot landed there, you would see the 6 1/2 lengths.Too much/too soon can be disruptive. Start with 6.5 shoe lengths, then if too much, back off until she finds the distance she can stride, and maintain form. There will be a point where you find that sweet spot, then work to improve a couple inches every so often. Eventually, I believe that somewhere between 6-7.5 shoe lengths is a goal.
She didn't say anything about cocking the wrist, but she is looking for a 12-6 spin on her FB. Right now, she either has a bullet spin, or a 1-7 spin. She doesnt want her turning her hand all the way to palm down after release. she wants fingers up. Since the last session, she's been able to limit the turnover to fingers facing first base, and to be honest, her rotation has improved quite a bit. Maybe she's giving her a target that's extreme so if she gets half way there she's got the proper technique? I don't know. I understand the global concepts quite well. It's these fine tuning and corrective measures that I struggle with. Is it good, is it OK, is it horrible what she's teaching. SHe's not teaching hand behind the ball... she specifically tells her to rotate her hand from palm facing third when her arm is directly behind her toward 2nd base and her hand rotates to release with fingers up.
