Protest Denied -- LL

[Buster Light]

I really don't know about LL but it sounds just like the FED rule.
A starter can re-enter in the same slot in the batting order.
If an improper batter takes his turn at bat, which happened
in your case, and it is recognized while he is at bat a proper
replacement is made and NO penalty.
If he gets on base, then if the improper batter is recognized
BEFORE the first pitch to the next batter, he is OUT.
If a pitch is made to the next batter, then it is too late and
the impropper batter becomes legal. The proper next batter would
then be, in your case, the number 9 slot.
