  • Manager/Assistant Coach will work pitching machine when their team is hitting.
  • To qualify as 8u, the player must be born on or after 5/1/09.
  • 8U 5 pitch limit - if 5th pitch is fouled off the batter continues hitting until the ball is put in play or he/she strikeouts.
  • No lead offs or steals.  Leave base on contact.
  • Play is declared dead once the lead runner is contained or gives himself up from advancing.  Throwing the ball back to the pitcher will not “kill” the play.
  • Bunting and fake bunting is allowed.
  • No slash bunting allowed(i.e. Fake bunt then swing.  Result regardless of contact or not is dead ball, runners return, batter is automatically out)
  • The player that assumes the pitcher’s position must remain within the “mound” 8-ft.-diameter circle, behind the machine, and on one side or the other until the ball is hit.  If the pitcher violates any of these requirements, then (1) The play will stand, even if the pitcher is involved in the play, and (2) The umpire(s) will warn the violating pitcher’s manager that if that same pitcher violates one or both requirements again, he/she will have to be removed fromt eh pitcher’s position.  The player can assume another position but cannot re-enter as a pitcher in that game.  The player may not be ejected from the game for this infraction.  First base and third base may charge as close as they wish when a player shows bunt.
  • If a batted fair ball hits any part of the pitching machine without touching any defensive player first, the ball is immediately dead.  The batter will be awarded first base.  All other runners return to the base that they occupied before the ball was hit unless forced to advance as a result of the batter being awarded first base.  If a batted ball fair ball is first touched by a defensive player and then hits any part of the pitching machine, it is a live ball.
  • 5 run rule per inning except the 6th inning will be unlimited.
  • No more than 10 players will play on defense at a time (4 outfielders must start play in the grass). You may start and end with 8.

* All managers (home and visiting) are required to check in at the tournament table at their complex 1 hour prior to the start of their game to detect a home team and collect game balls.



All games in pool and bracket play will become official after the team that is behind bats 4 times.  If a game gets canceled prior to that happening the home book should track how much time is left in the time limit for when the game resumes.  It will resume exactly where it left off.



A team may start with either 10 or 11 (with EH) or the entire roster in the line-up.  Once the game is in progress, a team may play with as few as 8 players due to injury, however, any vacated spot in the batting order will be an out each time it comes up in the game.  No team may drop below 8 players in the lineup.

Teams may elect to bat 10, or 11 (with EH) or the entire roster.  All players in the batting order will be considered a part of the line-up and they can substitute freely on defense.  Players cannot play defensively unless they are in the batting line-up.  The EH will be treated like any other defensive position for substitution rules.  Any batter not in the lineup to start the game MUST be subbed in for a dedicated player, and take their position in the batting lineup.  Those players are then married.  The starting player can re-enter the game ONCE.  The substitute player cannot re-enter the game once removed. 

PLEASE NOTE: Each player is only allowed to be rostered on ONE TEAM entered in this tournament.  If it is discovered that a team uses a player rostered on more than one team, both teams will forfeit each game that the player appeared in.



Courtesy runners are allowed at anytime for the pitcher or the catcher.  You must use any player not currently in the batting order or the last batted out if batting the entire lineup.


If there is an injured player and the team has no eligible subs the opposing coach will select which player will enter the game.

Good sportsmanship is always expected.  Our umpires will strictly enforce the rules of good sportsmanship.  If a manager/coach/player is ejected from the game, he will automatically be suspended from the next two games.  If a parent is ejected from the field or complex, his player is also ejected.  Both are suspended for 2 games.


The complex is a drug/alcohol/tobacco free complex.  Any violation of this will result in IMMEDIATE removal from the complex by the individual for the remainder of the tournament.  NO EXCEPTIONS.  Mangers are responsible for making their team parents aware of this.


There are no grills, or open flames allowed on the complex.



Winning team must enter score IMMEDIATELY following conclusion of game.   Bracket play begins in most divisions on Sat evening so this is important.  Missing scores will count as a 7 – 7 tie.
