An end cap for a hollow aluminum bat having a barrel with a substantially constant external diameter area defining a hitting zone. The end cap is constructed of rigid plastic material and includes a reduced diameter inner end which telescopes into the end of the bat. The barrel includes a peripheral groove in the internal surface adjacent the end of the bat and the reduced end of the cap includes a peripheral ridge received in the groove to anchor the end cap to the barrel. The distal end of the end cap is constructed with a concave end surface which moves the weight of the end cap axially inwardly in relation to the end of the aluminum bat. The end cap may include a conically shaped solid weight area extending axially inwardly from the inner surface of the end cap to increase the load at the end of the bat and also move the increased load inwardly in relation to the end of the bat.
