Softball Official Rules (1936). Rule 9-Fairly Delivered Ball
Strikes-When Umpire Shall Call One Strike
Section 1. A fairly delivered ball is one pitched by the pitcher while standing in his position and facing the batsman, that passes over any portion of the home plate before touching the ground, not lower than the batsman's knees nor higher than his shoulder. For every such fairly delivered ball the umpire shall call one strike.
IMO, the strike zone morphed to what it is today due to pressure from MLB teams. Since the management of MLB is driven by the income generated by the players, the umpires were probably instructed to call the knees to the waist. What happens if they did not? As we have seen over the years, there is a line of baseball umpires just waiting to get into a MLB ballfield.
Yeah, they told them to bring it up a couple years ago, but have we seen anything much higher than a ball's width above the belt?
Well, like everything else in this country, if we see something on TV, it must be real life and we deserve to have it at home.
Everyone trumpeted NCAA's introducing the "sternum" as a boundry for the strike zone, but it is not more a discernable reference point than a freckle on the batter's chest.
