Look at it this way.....

In NCAA there are four 'classifications of bad bats' (my phrase).....

#1) ILLEGAL
#2) NON-APPROVED (Not found on the current NCAA bat list)
#3) ALTERED
Anyone of these three will become....
#4's) INAPPROPRIATE
If you discover a #1, #2, or #3 during the pre-game bat check, and follow the proper procedure (per 3.3.4) for removal.

3.3.1.1- 3.3.1.8 Covers what happens if a bat that's a #1, #2, or #3 makes it way into the batters box:
#1) REMOVE BAT
#2) REMOVE BAT/EJECT BATTER
#3) REMOVE BAT/EJECT BATTER
In all cases these bats have now become.....
#4's INAPPROPRIATE

When you have a #4 in the game you now have REDISCOVERY of an INAPPROPRIATE bat (3.3.4)
When this happens (in addition to removing the bat) the following three things will occur:
1) An out
2) Ejection of player
3) Ejection of head coach

Sorry for the length, it was the only way I could get my thick skull around it when all this started last year.
