The anchor utilizes a pair of horizontally-offset male/female connections between the base and the anchor, the outer one of which connections is adjacent the outer edges of the base so as to minimize the effects of torque applied as when a player slides into a base while attempting a "steal". The horizontal surface area of the anchor is relatively large to enable a dirt-covered anchor to be easily located. Important advantages of the design are to avoid anchor obstruction of dragging equipment when the bases are removed, protecting both the equipment and the anchors, and to minimize risk to a player stepping over an anchor which does not have a base covering it.
