Balk or no?
NFHS ruleset.
This is from a game that I watched - I wasn’t umpiring.
This was his windup delivery. He did it the same way every time so there was no material variation in the pause that you’ll see, no reasonable way to call it deceptive.
It was allowed for the entire game and I can’t figure out why they didn’t call an illegal pitch [edited to specify illegal pitch instead of a balk] a balk because of the pause.
