Abstract

A rollable sports ballast base for supporting a sports apparatus support member comprising a base member having a top and bottom surface. The bottom surface contacts a support surface such as a driveway or other playing surface. There is at least one wheel assembly, retractable from a lowered position to a raised position. The wheel assembly includes a pivoting connector coupled to the base member and a wheel bracket coupled to the pivoting connector. The wheel bracket includes an axle, at least one wheel, and a handle extending outwardly from the wheel bracket. The handle is used to pivotally rotate the wheel assembly about a transverse axis. When the handle is rotated away from the base member, the wheel assembly is placed in a lowered position whereby the wheel contacts the support surface thus separating the bottom surface of the base member from the support surface.
