A bowling aid adapted to be mounted on either the bowler's index or little finger. The aid is a sheath into which the bowler's finger is inserted. Appropriate padding is provided in the sheath for gripping and protecting the finger. The padding can include a full-finger insert having removable serrated longitudinal sections. On the outer end of the sheath there is provided a plate which extends outwardly from the sheath under the head metacarpal joint of the bowler's index finger and part of the palm of the bowler's hand and is provided with a concave surface with a frictional coating thereon for assisting the bowler in gripping the bowling ball. The concave surface and friction coating extend along the length and width of the sheath. The bowler presses the plate and the length and width of the sheath against the surface of the ball to generate enhanced control during ball release. The sheath can define a gap along its length with a fastening system attached to the sheath to accommodate varying finger sizes.
