Abstract A practice baseball bat having an elongated shaft of predetermined length. One end of the shaft has a handgrip portion having a plurality of spaced apart and aligned raised portions which extend between the fingers of a batter's hands so that when the bat is swung, the raised portions will be moved from a first up position to a position in the direction of which the bat is swung. The bat further has an elongated enlarged cylindrical ball contact portion which extends intermediate the ends of the shaft and adjacent the other end of the shaft, the ball contact portion being coaxial with the shaft. The other end of the shaft defining a nub extending from one end of the enlarged portion to the end of the bat.

Independent Claim
175 words
A practice baseball bat, comprising: (a) an elongated rigid body portion, said body portion having a substantially constant diameter and having distal and proximal ends thereof; (b) handle means at said proximal end for accommodating both hands of a batter when the hands are positioned in close relation to said proximal end of said body portion, said handle means further comprising means for visually indicating said rotation of the wrists of the batter from a first resting position, to a position when contact is made with a ball; (c) an enlarged batting portion made of a material different from that of said rigid body portion, said batting portion being an enlarged area positioned near said distal end portion and extending a predetermined distance along the length of said rigid body portion, said enlarge portion representing that portion of said bat in which contact with a ball is to be made; and (d) said elongated rigid body portion at said distal end portion extends past said enlarged batting portion to define a nub of said bat.
