The extra hitter position can be substituted but can't be dissolved. All age groups can bat 9, or 9 with an EH/DH (Designated Hitter) if they choose they may bat the entire lineup. Teams in the 9 through 14 age brackets may choose to bat their entire lineup and have free substitution. If this option is chosen, the last out will be the courtesy runner.

18. Courtesy Runners: A courtesy runner may be used for the pitcher or catcher. However, The courtesy runner must be a substitute player. He may run for the pitchers spot every time it comes up in the game. A different substitute must run for the catchers spot.

If a team is batting the entire roster, the last out will be the the courtsey runner.

19. Visits to the mound: Each team is allowed three charged visits to the mound within a game. A charged visit is a trip in which the manager or coach does not remove the pitcher. After the three charged visits are used, every trip to the mound after that will result in the pitcher being removed. An uncharged visit is when the manager removes the pitcher from the mound. This visit will not be a charged visit. Remember, charged visits are cumulative for the entire game. No restrictions on visits per inning.
