Abstract: A baseball bat, that is formed of an elongate shell including a striking section, a handle section and a tapered section between the striking section and the handle section, further includes a tubular damper member received within a portion of a hollow cavity of the striking section. The tubular damper member is reduced in diameter relative to the hollow cavity and is supported by a foam layer extending about a circumference of the tubular damper member and which is under resilient compression between the tubular damper member and the striking section of the shell which surrounds the tubular damper member. A barrier layer between the foam layer and the shell is bonded with a first adhesive to the shell and with a second adhesive to the barrier layer to prevent the first adhesive from migrating into the foam layer.
