Abstract
A safety base comprising a cushion and root formed of a resilient material with a protective wrapping and a ground support having an aperture for receiving the root and holding the base in a desired orientation on the playing field. The force of a player sliding into the base deforms the base and pops it free of the ground support without injury to the player.
