NFHS Rule Change - pitcher foot
 

Another rules change is an adjustment to Rule 6-1-1 regarding fast-pitch pitching regulations. Pitchers must now take a position with the pivot foot in contact with the pitcher’s plate.
Previously, pitchers were required to have the pivot foot on or partially on the top surface of the pitcher’s plate.

“The change allows for different styles of pitching and permits them to place their feet where pitchers feel most comfortable,” Searcy said. “The rule now clarifies that part of the foot must simply be in contact with the pitcher’s plate.”

Not that I think this is a bad change, but it strikes me as funny that Fed rulemakers give "accessibility" as the reason for their pitching rules, yet follow NCAA with almost every change except starting with both feet on the pitching plate.

Practically speaking, this changes almost nothing, except it is now explicitly legal to have just the pivot foot heel bone in contact with the front vertical edge of the plate, or some other situation where the foot is not on top.
