A ball bat includes a segmented or decoupled barrel, which reduces the axial stiffness and BBCOR of the barrel, while providing little or no increase in the bat's moment of inertia. Segmenting the barrel, alone or in combination with other performance-reducing features, may be used to lower the BBCOR (or other specified performance characteristic) of the ball bat below the performance limits of a given regulatory association or other governing body.
