The River™

Expand the zone. Defined as "the area from the edge of the plate to the edge of the batter's box."  AKA the Ghost Zone, Shadow Zone, Stri-Ball Zone.  Numbered quadrant flaps provide specific feedback on pitch location.  Induce batters to chase the Pitcher's Pitch, or induce the umpire to call this borderline pitch a strike.  The River has quickly become our most popular product at all levels:  baseball, softball, youth, high school, college, professional.
