A conventional baseball (softball) first baseman's mitt includes two layers of protective padding in the areas above and below the center axis of rotation of the metacarpalphalangeal joint of the index finger. One layer of padding is a slow release foam material and the other layer of padding is a foam rubber, neoprene, or other foamed elastomeric material. Additional protective padding may extend to the areas above and below the center axis of rotation of other joints of the index and long fingers.
