A lacrosse stick for reducing the rebound of a ball caught therein. The head of the lacrosse stick has a socket for receiving the shaft, and incorporates one or a plurality of flexible elastomer pads within or as part of the handle or socket, where the head and handle meet, to damp impact and rebound. The flexibility of the damping pads produces a “give” that minimizes the rebound of a pocket after being impacted by a ball. This pocket dampening limits the movement of the ball and makes the ball easier to control and to retain in the pocket. The precise location of the dampening material on the lacrosse head may be varied to control the degree of pocket “give” in response to, for example, the force on the pocket created by a ball impacting the pocket during a catch or swinging in the pocket during cradling.
