Abstract: An athletic game marking device for use in baseball, softball, and other activities to greatly reduce injuries from sliding into and stepping onto the marking device and to improve the visibility of the marking device. One or more layers of resilient materials are attached to a base member. Side projections are attached along the peripheral sides of the base member and extend vertically upward. The side projections are made of a material selected to allow the side projection to deform or bend when a force is applied, such as when stepped on by a base runner, then return to essential the original upright position. The side projections may be colored or imprinted with a design to increase visibility.
