Abstract: An instructional and amusement device for teaching the art of correctly pitching a baseball, comprising a plurality of resilient target blocks mounted within contiguous support racks. When the apparatus is used as a training device, a pitched ball striking a target block will activate a mechanical switch adapted to close an electrical circuit to indicate, by audio and visual display means, either a "ball" or a "strike". Mounted at various locations within the blocks defining the normal "strike" zone, are a plurality of individual impact sensors comprising outwardly protruding plunger-type mechanical switching devices. When the apparatus is used also as an amusement device, a pitched ball striking one of these switching devices will close an electrical circuit, indicating by audio and visual means, either a "ball", "strike", "hit", "double", "triple", "homerun", "out", or "foul".
