Age divisions of each player are determined as of April 30, 2019.  There are no age waivers granted for this tournament.  No exceptions. 



It is the responsibility of the coaching staff to carry birth documentation for all of the players on their roster at all times during the tournament.  Birth certificates, passports, Cal Ripken/Babe Ruth League ID cards, state IDs or any other government issued documents are sufficient (must list full name and birth date).

Age verification can ONLY be requested by opposing manger or tournament representative.  Parents cannot protest the ages of other players.

If the team is unable to provide sufficient documentation, the team will forfeit the current game with a score of 7-0, and will not be permitted to start another game without the appropriate documentation.

Managers may request the age verification of players on another team, only before or during a game AGAINST THAT TEAM.  Age verification may not be requested after a games' conclusion.  A tournament representative may request documentation at any time.



Bracket Play-  No new inning start after 1 hour and 45 minutes (no drop dead) for 8U-12U

                   No new inning start after 2 hours (no drop dead) for 13U-15U


       Must be a winner / Higher seed is home team / No time limit in Championship game only

       Home Team gets third base dugout, visiting team gets first base dugout

             *Exception – if team is playing the following game on same field, they may stay in same dugout. 

*  There should only be a total of 2 minutes between innings (last out to first pitch).  Have your pitcher and catcher ready.  No meetings on the way out to the field.

*  Start Times-  Game will start when 1st pitch is thrown.  Coaches should agree at start of game with ump.

* 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.



In all divisions with 9 teams or less, championship seeded bracket will be a normal single elimination bracket.  In divisions with more than 9 teams, all teams seeded above number 8 after pool play will play a consolation game (ie with divisions of 10, seed 9 and 10 would play.  In divisions of 12, 9 would play 12 and 10 would play 11).  None of these teams will be included in the championship bracket.  In divisions with more than 12 teams, the division will be split into 2 separate brackets based on seeding following pool play.  Seeds 1-8 will make up the “GOLD BRACKET”.  Remaining seeds will make up the “SILVER BRACKET”.  These brackets will then play 2 completely separate championship brackets from there on out.  A Gold bracket winner/runner-up will be named.  A Silver bracket winner/runner-up will be named.  The winners will not face each other.  In divisions of 11, seed 10 would play 11 a consolation game, and seeds 8 and 9 would play as part of the championship bracket.



There will be a slaughter rule in effect.  There is no  per-inning run limit for ANY age division.


15 runs after 3 innings (2 ½ if home team is ahead)

10 runs after 4 innings (3 ½ if home team is ahead)

*  If coach fails to present completed pitching affidavit at plate conference that team may only be allowed to pitch each pitcher a maximum of 2 innings per pitcher.

*  Managers may request the pitching affadavit of another team, only while pitcher in question is the pitcher of record.  Affadavits may not be requested after a games' conclusion.  Only an opposing team's manager may request documentation.



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 9 or 10 (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 9, or 10 (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.


Head-first sliding allowed at all bases.



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



Forfeits will go down as 7 – 0 in the record.



1 per defensive inning or 2 for the game (per pitcher) without a change.

There are no protests in this tournament.  The umpires ruling shall remain final in all scenarios.



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.


Bracket play begins in most divisions on Sat evening so this is important.  Missing scores will count as a 7 – 7 tie.
