LL Pitching Rule and protesting illegal pitcher

[parrothead]

Question 1 - Did LL change any rules from 16 to 17 about P eligibility? I know last year the first limitation was catching 4 innings couldnt pitch, but I dont have a green book and when I have looked online, that limit is no longer listed at the top, is that still in play? I know also is was specific that catching 1 pitch in the 4th inning behind the plate constituted 4 innings of playing catcher. You couldnt have a player Catch the 4th and yank him with 2 outs.

So just want to check and make sure this didnt change.

Question 2 - when to protest? My thought is that in a regular season game, this is not a forfeit situation like a Tournament, so my thought is that if you protested that the game would be picked up at the time the illegal player entered the game and obviously not eligible to P, but if you just let it play out let the kid pitch the 5th and 6th and then call it, you not only would get to go back to that spot, but..wouldnt those count as pitches thrown so he could also not pitch his next game that week if he went over a certain threshold?
