6-4-3 = 2
I believe you'll find that JS addresses this somewhat differently in the Drive thread, but I see your DD driving with maybe too much emphasis to get open, rather than to drive forward. I like the cue of driving hard to the target with the backs of the hands and stride toe. I also like the thought of driving squarely towards the target with the hips/shoulders, but letting the arm circle open up the torso naturally.
Notice how the hips, shoulders and stride toe seem to be driving to the target vs trying to get open?
L,
You already know this... or have heard this from me before, but the biggest issue... by far... is the fact that she is releasing the ball outside her shoulder. It is a country mile from her body. Otis's DD HAD this issue... it was easily the thing that killed her control and power. She's spent the last couple weeks addressing this fix... and you should see her now... completely different pitcher. Even took down her dad... but that's another story.
How? She went back to basics in drill... working on Lock-It-In and 9 drills... with the sole focus of starting with her hand in the correct position (against thigh, hand inside)... backchaining and then forward chaining... with the sole focus of getting back to where she started.
As riseball said, there is some anchoring going on... in the form of a long and steady push... as opposed to a "quick stick" into the front of the rubber. Her foot is rolling... instead of striking the front of the plate. I'd work on that, too.
Personally, I think she opens fine... but I do see a tendency for her to turn her stride foot inwards, prematurely. Take a look at the wall sprints on the first page of the DM sticky. Note how the toe is pointed at the target the entire time... and in that drill, the thigh is perpendicular while the toe is still pointed forward. During a pitch... I'd recommend completing the knee driving out first... and then tell her to get that foot down.
I'd experiment a little if I had you guys in clinic... as getting to the bottom of the premature turn-in of the stride foot might be from a bunch of things. Even though I wouldn't recommend it for the majority of people... I'd probably have her trying landing with less of a stride foot angle... as it may be something as simple as that... and that might be worth a stab... even if unsuccessful.
Honestly... I don't see a lot of differences in your DD... when compared to the stills Ken posted. Her hips are open, her glove shoulder is getting ahead of her throwing shoulder, etc. It's actually a REALLY good position to be in. I worry that if you try and square her too much, you're going to damage an otherwise smooth over-the-top motion that she currently has. It's probably her best trait... just food for thought.
Lastly, her torso is leaning towards third, too much. You might try the tip-toe drills SBMOM posted a little while back... especially when working on bringing that circle in closer to her body.
Anyway... get her to work, she has a bunch of quality traits!
P.S. Those gifs are huge, man! (like 25 meg!) Killing my bandwidth! Glad you sent me the Youtube link!
