The first phase of energy has been created as the rear leg drives forwards and the the throwing arm extending backwards. As the rear hip rotates the pelvis open, the front foot settles into the ground and becomes responsible for stabilizing and transferring the energy back up the body in the Transfer Phase.
The Transfer Phase happens extremely quick but its role is vital to the proper acceleration of the trunk and arm in Acceleration Phase 2. If the pitcher has been taught and trained properly up until this point, his pelvis should be opening more freely because of the stretch of his body and you will notice the front heel will begin to extend out in front of the body and open prior to landing. This is a good sign! The front HEEL making contact with the ground first and not the ball of the foot has many benefits to the timing and transfer of energy throughout the rest of the throw.
