Abstract
Abstract A rotating grip comprising a non-slip outer surface and a high slip inner surface and which can be installed on the handle of a baseball bat to enhance the user thereof, is described. The grip can be covered by a conventional sleeve-type grip and has a novel notching means to hold the rotating grip in place. When used, the rotating grip enables the proper alignment of the hands to occur automatically and thus create a level and smooth swing. This swing will insure more direct hits on the baseball.
