A ball bat extending about a longitudinal axis. The bat includes a handle and a barrel portion having an outer surface and including a proximal member and a distal member. The proximal member has first and second end regions and the distal member has third and fourth end regions. The first end region is coupled to the handle portion, the second end region of the proximal member is coupled to the third end region of the distal member, and the fourth end region of the distal member is coupled to an end cap. The proximal and distal members are formed of first and second materials, respectively. The second material is a fiber composite material, the second fiber composite material of the distal member is co-molded to the outer surface of the second end region of the proximal member. |
