>>>,Could someone explain the concept of "a rearward force as the bottom-hand is being pulled forward." I get the idea that the the bottom hand pulls forward, but not sure that rearward force refers to pushing the bat. <<<
Hi PMB
In regards to the top-hand, it should not be �pushing the bat� forward as the swing is being initiated. In the high level swings we saw in the derby, it was the pulling rearward of the top-hand and the rotation of the forearm as the elbow lowered to the side that accelerates the bat-head back toward the catcher from its launch position. � Below are a couple posts from the Archives that explain this further.
