An improved baseball bat comprises a tubular core of rigid materials having a first section to support a handle and a second section to support a striking portion. The second section of the core has a diameter relatively larger that of the first section of the core. A covering member of semi-rigid materials has a handle portion embracing the first section of the core and a striking portion embracing the second section of the core. Whereby, the baseball bat has a light weight, good equilibrium, and high structural strength for a good performance.
