Abstract: The method and apparatus for improving the performance of a batter. The apparatus includes sequencing lights (38) which are representative of a ball moving toward an impact zone. Further included are light indicia (46 and 48) which inform a batter that the pitched ball will either be a ball or a strike so that the batter may determine whether or not he should swing the bat. Also included are means to generate an electrical signal to indicate that the strike light (46) is illuminated. First and second light beams (18 and 20) are provided which pass through the ball/bat impact zone and are located at selected and known distances apart such that the bat swing through the impact zone will sequentially interrupt both first and second beams (20 and 18). First and second sensors (22 and 24) are also located for receiving and sensing the presence of the first and second beams and provide second and third electrical signals, respectively, if the beams are interrupted.
