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.
