Abstract: A finger grip insert for a bowling ball is formed of a resilient hollow body having an outer configuration adapted to be inserted into a finger hole of a bowling ball. The outer end of the insert is open to permit insertion of a bowler's finger into the interior of the hollow body. The interior of the body has a generally triangular shaped cross section defined by three spaced flat sides with respective concave portions of the body extending between respective pairs of the flat sides to allow the bowler's finger to stay in a relatively natural position while enhancing the feel and adding lift and power to the bowler's delivery as a result of the substantial finger to insert contact area provided by the finger grip insert.
