ABSTRACT:
A bat for baseball, softball or other sporting games comprises a first member extending from a first, butt end of the bat to form a handle region of a first diameter, and a second member extending from the opposite, barrel end of the bat to form a barrel region of a second, larger diameter. The two members are tubular or are shaped at their innermost ends to form interengageable region which overlap telescopically at least in a central region of the bat, with the outermost member being shaped in the central region to form a tapering transition zone between the different diameter handle and barrel regions. The members are secured together along the length of the overlap, and the first member is of material having a higher flex modulus than that forming the second member. One or both members may be of fiber reinforced, or composite, plastic material.
