Abstract: A baseball base and installation apparatus whereby the base has attached to the bottom surface thereof a post having a non-circular cross-section. The installation apparatus includes a brace member, an anchor member having a top socket portion and a bottom screw auger portion, the top socket portion having a hollow interior complementary to the configuration of the non-circular post, and the screw auger portion being a flat strip of metal formed into a helical configuration. The brace member has a non-circular lug portion of a configuration complementary to the interior of the top socket portion and a handle portion for rotating the lug portion. The lug portion is telescopically inserted into the socket portion, the handle is rotated to install the anchor member into the ground. After the anchor member has been installed into the ground the brace member is removed and the post of the base is telescopically inserted into the socket portion.

Abstract: A portable pitching mound with a body having a generally convex upper surface and a flat lower surface defined by an arcuate outer edge portion terminating in a chord-like front edge. The upper surface is formed with a flat rear surface area and a parallel flat front surface area offset downwardly of the rear surface area. The front and rear parallel flat surface areas extend, respectively, forwardly and rearwardly from an upstanding shoulder which is parallel with the chord-like front mound edge. The upstanding shoulder is located midway between the chord-like front edge and the arcuate outer edge portion at the rear of the mound.
