She is trying to turn the barrel but is having a hard time because her weight is shifting to the front side. You can't turn the barrel once your weight gets to the front leg. When tossing that deep she has to have the goal of getting behind the ball. The only way to do that is to stay with the rear hip.
Your DD is shifting her weight forward to soon and her hands go with it. Hands move forward before your DD can get into a good top hand swivel position.(swearing in,elbow under hands) From there your DD pushes the bat/barrel to contact. Push the hands towards the pitcher. I see your DD swing more with her arms which is where she believes and gets her power for her swing. You want the hips to pull the hands not the hips to push the hands. This is a problem that many hitters seem to have regardless of their age. I am reading this now on 2 other sites same issue with much older hitters. I posted the 2 gifs because to me they are almost the same. If this was my DD I would go back to just the tee. I would not be in a big hurry to move on to soft toss, or live pitching for awhile. I also would be trying to get more stretch/seperstion in your DD swing. I believe if she grasps this concept it may help get the hips leading. Still alot to like in a 9yr old hitter that has come pretty far. JMHO.
