Abstract
A finger hole insert for a bowling ball which is formed of a resilient tubular body and is adapted to be inserted into a finger hole. The insert has an oblong cylindrical inner wall surface defining finger openings at opposite terminal ends of the insert which are sized to permit insertion of a bowler's finger therein. The finger openings have thickened parallel planar finger pads therein adapted for cushioning the bowler's finger. The finger openings also have opposed arcuate finger pads for augmenting the spin and lift applied during delivery of the bowling ball. In this manner, the bowler has a preferential choice between the two functions provided by each finger opening of the insert.
