Finished viewing Hillhouse's pitching DVD, which I would recommend especially for beginning pitchers, but had a question about stance. Before starting the pitching motion, he suggests that only the pivot foot HEEL be placed on the front of the pitching plate, the rest of the foot is in the dirt in front of the plate? The result is that when the pitcher pushes off, she is driving off of the dirt with the ball of her foot instead of driving off the plate. Would she not LOSE power because she is not drving off the plate ("starting block") with all of her force?
