NFHS "ball four" mechanic

[CecilOne]

Count - second strike, third ball, after a delay, when I perceive confusion, when asked (minimal me aspect in game).
Used to after third pitch, especially slow pitch, but if not strike 2 or ball 3, count is 2 and 1

Ball four - "ball", mask in left hand facing BR & 1st base, pause, "ball four" if no reaction, watch any 3rd base runner.
HBP - "dead ball", if not obvious - point & announce "hit batter"; check runners, then same as ball four

Never point to 1st or give instructions.
