Abstract: An insert to provide stiffness to a baseball glove. Conventional baseball gloves have cavities for receiving the digits and palm of a hand. The insert includes a central expanse, a first elongate extension extending outwardly from the central expanse, and a second elongate extension extending oppositely from the first elongate extension outwardly from the central expanse. Preferably, a central elongate extension extends intermediate the first elongate extension and the second elongate extension. The first elongate extension is fittable within a digit-receiving cavity of the glove, such as that intended to receive a thumb, the central elongate extension is fittable within another cavity of a glove, such as that intended to receive the middle finger of a hand, and the opposing elongate extension is fittable within a cavity of the glove corresponding to the pinkie of a hand.
