Abstract
Abstract A ball tee is provided having a base and an upstanding column carried by the base and having means for supporting a ball thereon. The column and base are made entirely of a yieldable resilient material enabling the column to be struck by a ball bat with the column and bat remaining intact and enabling the base and the major portion of the column to be easily flattened upon applying compressive forces thereagainst to thereby assure a person falling thereon will not be injured.
