ABSTRACT:
A ball bat includes one or more focused flexure regions located predominantly or entirely in the transition section between the barrel and the handle of the ball bat. One or more of the focused flexure regions may additionally or alternatively be located partially or entirely in the barrel and/or the handle of the ball bat. The one or more focused flexure regions each include a radially inner structural region and a radially outer dampening region for reducing the local axial stiffness, and improving the flexure, of the ball bat at the location of the focused flexure region.
