Abstract
An end plug for a tubular bat includes a rigid plug member that forms the closure of the barrel portion of the bat. The plug member has radial supports formed thereon. The end plug further includes a rigid reinforcing member that cooperatively interconnects with the plug member to reinforce the supports formed thereon. A resilient member supports the plug member and the reinforcing member within the barrel portion of the bat. A method of forming and installing an end plug includes interconnecting a plug member and a reinforcing member such that the reinforcing member reinforces supports formed on the plug member. The plug member and the reinforcing member are then positioned within the opening of the barrel portion so that the plug member forms a closure of the barrel portion. Liquid material is poured into the handle end of the bat and allowed to drain through the frame of the bat until it rests on the plug member. The liquid material then solidifies to form a support member.
