Abstract: A base assembly for playing softball has a base, and a ground-engaging elongated plate on the bottom side of the base. The plate is elongated, stiff and has a length greater than the width of the base. A strap passes horizontally through the sides of the base and then through slots in the plate. The strap ends are folded back and fastened to the bottom side of the plate in a tight fitting arrangement. A pair of spikes are received through openings adjacent the ends of the plate to anchor the base to the ground.
