ABSTRACT:
A baseball base incorporates an anchor defining a top surface and post or the like for inserting into the ground to secure the anchor in place, and a baseball base which has a ferromagnetic plate secured to the underside. The anchor incorporates a plurality of parallel, spaced elongate bands which constitute alternating north and south magnetic poles, so that the plate and baseball base can be secured and retained in place on the poles. By changing the size of the plate, the force required to separate the base from the anchor can be altered.
