7. Each league must designate the scorekeeper or another game official as the official pitch count recorder.
a. The pitch count recorder must provide the current pitch count for any pitcher when requested by either manager or any umpire. However, the manager is responsible for knowing when his/her pitcher must be removed.
b. Both managers must confer at the conclusion of each inning and agree upon the current pitch count.
8. The official pitch count recorder should inform the umpire-in-chief when a pitcher has delivered his/her maximum limit of pitches or innings for the game or week, as noted in Regulation 3a & b . The umpire-in-chief will inform the pitcher’s manager that the pitcher must be removed in accordance with Regulation 3a & b. However, the failure by the pitch count recorder to notify the umpire-in-chief, and/or the failure of the umpirein-chief to notify the manager, does not relieve the manager of his/her responsibility to remove a pitcher when that pitcher is no longer eligible.
9. Violation of any section of this regulation can result in protest of the game in which it occurs along with a 1game suspension of the team manager. Protest shall be made in accordance with individual division rules.

a. Prior to taking the mound, if a pitcher plays the position of catcher his maximum allowable pitch count is reduced by 20 pitches for each inning caught
b. A pitcher who delivers 51 or more pitches in a game CANNOT play the position of catcher for the remainder of that day
Example - A player plays the position of Catcher for the first 2 innings of the game and then goes in to pitch. If his maximum allowable pitch count was previously 85 pitches, he now begins with a max PC of 45 pitches (85(2x20)).
60/90 Fields - Catcher limitations at this level are at the manager’s discretion.
12. NOTES :
a. The withdrawal of an ineligible pitcher after that pitcher is announced, or after a warm-up pitch is delivered, but before that player has pitched a ball to a batter, shall be considered a violation. Little League officials are urged to take precautions to prevent protests. When a protest situation is imminent, the potential offender should be notified immediately.
b. Pitches delivered in games declared “Regulation Tie Games” or “Suspended Games” shall be charged against pitcher’s eligibility.
c. In suspended games resumed on another day, the pitchers of record at the time the game was halted may continue to pitch to the extent of their eligibility for that day, provided said pitcher has observed the required days of rest.
Example 1: A league age 12 pitcher delivers 70 pitches in a game on Monday when the game is suspended. The game resumes on the following Thursday. The pitcher is not eligible to pitch in the resumption of the game because he/she has not observed the required days of rest.
Example 2: A league age 12 pitcher delivers 70 pitches in a game on Monday when the game is suspended. The game resumes on Saturday. The pitcher is eligible to pitch up to 85 more pitches in the resumption of the game because he/she has observed the required days of rest.
Example 3: A league age 12 pitcher delivers 70 pitches in a game on Monday when the game is suspended. The game resumes two weeks later. The pitcher is eligible to pitch up to 85 more pitches in the resumption of the game, provided he/she is eligible based on his/her pitching record during the previous four days.
