Abstract
Abstract A baseball bat characterized by an improved handle section which facilitates swinging of the bat during use to improve the batter''s hitting power and effectiveness. The handle section is formed with a dog leg configuration which imparts a laterally offset contour thereto relative to the bat longitudinal axis. The handle section is generally symmetrical in transverse cross section and preferably is circular in cross section throughout its length to facilitate gripping thereof.
