I can find it in the other associations rules but in strictly speaking U-Trip Slow Pitch where does it state that the batter must be within the confines of the batter's box to start play and effects otherwise (Delay strikes, etc)?

FP USSSA Rule 8 Sec 6. <b>A batter shall not delay the game</b> by failing to
promptly take her position in the batter's box within 20 seconds, (Tom's unfavorite
rule) or by stepping out of the box when the pitcher is on the pitcher's plate.

Realize this is FP, but SP should be the same. Not sure, don't do SP.

Dukat,

7-3-F says "The Umpire shall not give a call or signal for 'TIME' when a Batter steps out of position after a Pitcher has started his delivery motion".

Effect listed is that if the pitcher pitches, the umpire shall call a strike on each such pitch. The batter may take his proper position after any such pitch (within 10 seconds) and regular ball and strike count shall continue.

7-3-G "When the Batter delays entering the Batter's Box after the Umpire signals Play Ball. After 10 seconds the umpire shall declare dead ball and a strike shall be called on the Batter."
