Abstract
A breakaway safety base for use in playing baseball where the base is secured to a ground support by resilient deformable interengageable members carried on both the base and support which form a plurality of physical connections securing the base to the support. High-injury potential lateral loading forces on the base shear the connections to free the base for lateral movement across the support.
