Good. Right now she brings her upper rear arm with her as she moves her hips/tailbone forward. I'd rather see her create a 'stretch'. Visualize an elastic between the rear hip and rear shoulder ... or if you can, between the rear hip and the top hand. You want to get that elastic somewhat taut as the hips/tailbone are brought forward.
As an FYI ... when I say load the hands 'rearward' ... that rearward is not towards the catcher ... I'm talking about the "up & IN" action ... it's more like turning up the rear elbow, or rear upper arm, in ... it's like bringing the rear upper arm towards the third-base coach for a right-handed hitter.
One more thing. Your daughter has her hands "high" in her stance. That will make it more difficult for her to capture the "up & IN" loading of the hands rearward as she moves her hips/tailbone forward. So as you work through this ... test having a stance in which her hands are lower ... towards the height of her arm-pit ... and see if she can't develop the "up & IN" action from there.
One last thought for you .... a hand-pump like action can provide a means of keeping the hands back while the hips/tailbone move forward ... a 'hitch' like action. Just something else to consider here as you work your way through this.
Thanks. Some good info. We will probably work out this evening and get more video to post. She is also a pitcher and focused more on it in the past. Her travel ball coach is a very respected hitting coach also. We haven't had time to get with him one on one since November and she has picked up some bad habits. Thanks again for input.
