ABSTRACT:
A strike zone mask provides an image of a batter's strike zone for increasing the precision with which an umpire may judge whether or not a pitched ball was a strike. A lens carriage is provided within the viewing opening of the mask, the carriage and lens intercepting the umpire's field of vision in one eye. Lenses within the carriage have vertical scored lines defining the horizontal width of home plate, and a horizontal bar adjustably affixed to the front of the carriage across the lower portion of the lens permits adjusting the height of the strike zone to different players by aligning the top of the lens with the batter's shoulders and the horizontal bar with his knees.
