Abstract: A batter training device (10) is provided for training a batter (B) to effectively strike a baseball by controlling the batter's stance. The device (10) is positioned on the ground (G) in front of a leading foot (F) of the batter (B). During the batter's swing, the batter (B) steps forward with the leading foot (F) until the leading foot (F) strikes the device (10). The device (10) includes a rear plate (40) fixed to the ground (G) and a forward plate (20) hingedly attached to the rear plate (40). A spring (99) is oriented between the front plate (20) and the rear plate (40). The device (10) is oriented so that the front plate (20) will be located adjacent to a final destination for the leading foot (F) when the front plate (20) has been pivoted towards the rear plate (40) and against maximum spring (99) compression. The spring (99) is selected to exert sufficient force between the rear plate (40) and the front plate (20) so that the batter (B) must stride forcefully into the front plate (20).
