发明名称 PITCHING TRAINING AID
摘要 A pitching training aid includes a mat, a pitching rubber attached to the mat and indicia displayed on the mat to instruction a baseball player on how to pitch a baseball. The indicia includes the steps of “start,” “rocker,” “pivot/balance” and “step/release.” The indicia also includes a series of arrows which instructs the baseball player on the sequence of the steps. A straight line extends from the pitching rubber down a center of the mat to show where the “step/release” position should be. A top surface of the mat has an artificial grass surface and a bottom surface of the mat includes a nonskid material to prevent the mat from sliding during use. The mat may include two pitching rubbers and two sets of indicia on opposites ends thereof with one pitching rubber and indicia being used to instruct right hand pitchers and the other pitching rubber and indicia being used to instruct left handed pitchers.
