  10. Four (4) innings will constitute an official game.
  11. No new inning will be started after the actual game time has reached the 2 hour time limit. The game will end once that inning has ended.
  12. A twelve 12-run mercy rule is in affect after five (5) innings (four and a half (4.5) innings if the home team is winning) or ten (10) runs after six (6) innings (five and a half (5.5) innings if the home team is winning).

  16. Only adults are allowed to coach the bases and must stay in the coach"s area (the coach"s box or an area where one would normally be if unmarked) when on the field of play.


  1. Player may pitch no more than three (3) innings in a one game week with a maximum of six (6) innings in a multiple game week. For the purpose of counting games in a week, each week begins at 12:01 am Monday and ends the following Sunday at Midnight. For the purpose of this rule a single pitch thrown during an inning constitutes 1 inning pitch in regards to this limitation. Only for the end-of-the-year Playoffs, the games per week limit will be eliminated, but the innings per game limit will remain intact.
  2. Pitching limitations for 2nd year players (Note: Option B below must be declared prior to starting the game otherwise Option A is in effect. You cannot switch during the game):

    Option A: Teams will be limited to three (3) innings of a 2nd year pitcher during the first five (5) innings of a game and two (2) innings of a 1st year pitcher during the first four (4) innings. Any appearance by a 2nd year pitcher counts as an inning towards this limitation. For example: If you remove a 1st year pitcher during an inning, you must replace the pitcher with a 1st year pitcher to not count towards this limitation. If you replace a 1st year pitcher with a 2nd year pitcher this will count against your three (3) innings for your 2nd year"s pitching. Pitchers after the first five (5) innings may be 1st or 2nd year pitchers. Pitchers may not re-enter if removed earlier, or if they have used up their three (3) innings of eligibility for this game. For purpose of this rule, a 1st player is defined as a player who has not played before in the current league (excluding the previous fall season). The rule does not pertain to age and/or grade, but rather to experience only.

    For example, in 2015 spring league a player played in the Major League. In the fall of 2015, that player played in the Pony League. For the 2016 spring season, that player would be categorized as a 1st year Pony League player. If in the Fall of 2015 that same player played in the Major League, then for 2016 spring, the player is categorized as a 2nd year Major League player.

    Option B: Teams may elect that if they are short on 1st year pitchers to declare the option of throwing a 1st year player one (1) inning during the first four (4) innings. They will then be limited to one (1) inning each of 2nd year players for the duration of the regulation game. In essence, no 2nd year player can pitch more than one (1) inning in that game unless the game goes into extra innings, then the limitation is lifted and a 2nd year pitcher could pitch into the extra innings. Note: During the course of the game, a team may throw a 1st year player more than one inning but the 2nd year restriction will still be in place.

  3. Pitchers will be allowed to pitch on back-to-back days, but not three (3) days in a row.
  4. The pitching rubber shall be dictated by the home team or field restrictions, either 48" or 50" from the furthest point of home plate to the front of the pitching rubber.
  5. A pitcher will receive one warning when a balk is committed. After subsequent infractions, all base runners will be awarded a base.
  6. A pitcher is limited up to six (6) warm-up pitches between innings and up to eight (8) warm-up pitches following a pitching change either during an inning or between innings.
  7. No breaking pitches.
  8. Once a player has been removed from the pitcher position, that player may not pitch again for the remainder of the game.

  3. If a play is made at a base, a player must attempt to avoid contact preferably by sliding on plays at any base (except first base). A player may not jump (leave the ground) over the catcher to avoid contact with the catcher. If it is determined by the umpire that the player jumped over a catcher to avoid contact that player will be called out and the ball is dead. If unintentional contact is made, the runner may be called out and the ball would be dead (umpire"s discretion). If the act is determined to be flagrant, the offender shall be ejected. The umpire"s decision on the sliding rules is final.
  4. Catchers and pitchers may have an optional courtesy runner if they reach base with less than two outs.
