Abstract: A self-anchoring base for use on a baseball playing field comprises a platform having an anchoring means extending from the underside thereof for embedded engagement in the playing field. A protective cover surrounds the platform. The anchor means comprises two or more spikes spaced apart from one another. The two or more spikes are fastened to the platform by a mounting assembly defining a spike socket for each of the spikes. The self-anchoring base further comprises a cushioning material disposed on the top side of the platform under the protective cover. The self-anchoring base can be used as a standard stationary base. Alternatively, it can be used as a break away base by installing shorter spikes in the spike sockets.
