>>> After changing my daughter to the rotational swing ( it took almost a year (because of knob to the ball type teaching for years) before she incorporated most everything, quick shoulders being the last obstacle to over come). I still am having a problem with that last part of the swing which you call "hooking the bat". To me it just seems you just follow through naturally, but you seem to indicate that it is something more than that. I want to incorporate this into my daughter's swing but since I can't seem to feel it I need help in teaching it. Any suggestions.

> Congratulations to your daughter and thank you for the kind words. – You are correct in thinking that the “hook” in the hand-path occurs naturally with good rotational transfer mechanics. The rotation and “un-shrugging” of the lead-shoulder back to the 105 position will pull (or hook) the bottom-hand around the slower moving top-hand -- if the back elbow remains back at the batter’s side during rotation (the “L” position).

> The mechanics used by most hitters do not promote the hook in their swing. As I mentioned earlier, the hook occurs as the bottom-hand is being pulled back around the top-hand (BHT). Average hitters attempt to accelerate the bat-head to contact by extending the top-hand past the bottom-hand. Many of them also extend their lead-hand by un-flexing the elbow at contact. These actions result in the hand-path sweeping in a wider arc instead hooking as the bat is brought to contact.

There is something else going on during this point in the swing. The hips and shoulders decelerate sending the arms ahead of the hips. It's called the whip affect.

I have several views of the same swing from the back and side views and they tell different tale. The riew view it look like the hook affect is how you explained it. In the side view you can see the whip affect and the arms accelerated past and around the rotating body.
