Junk Ball Home Run Challenge Set

The special “dial-a-pitch” feature on the Junk Ball can be considered baseball’s newest performance enhancer, only less controversial than others. Based on the Bernoulli Principle that a baseball’s seams and speed affect its movement, the Junk Ball can be set to pitch curves, sliders, knuckleballs, and risers. Along with four configurable balls, this plastic “Home Run Challenge Set” includes a Sweet Spot bat and base markers for a proper backyard game — with no unfair advantages if everyone plays.
