摘要
A practice device for assisting a batter in learning a proper swing includes an elongated, lightweight, tubular member having two longitudinal ends which forms a longitudinal extension of the handle of the bat. The extension is circularly symmetrical about the longitudinal axis of the bat and has a fastener at one end for attachment coaxially of the member to the bat handle.
