MLSBA League Rules

• Team rosters must be submitted to the league by opening day. Final Rosters are due by week 5 of the season. Rosters may not be changed unless: The league decides to extend dates for final rosters.
• All teams may bat up to 10 players at their choosing. (Not required)
• You may DH only for the pitcher  
• All teams must announce all offensive additions, substitutions, and/or changes to the home plate umpire AND opposing team manager and/or scorekeeper. Only after this has been done will the added player be deemed a legal substitution. If a team fails to announce an offensive addition/change, the player will be called out as soon as he occupies the batter’s box and the lineup will revert back to the lineup in effect prior to the player entering the game. The unannounced player will not have officially entered the offensive lineup and is therefore still available.  [In case of injury, if this will bring you below 9 players and you have already made substitutions, a player who was substituted is able to re-enter the game. If you are batting 10, and a player is injured, you have to drop down to 9 players. No out is call on the 10th batter] 
• A team must have 8 players for an official game and may borrow a player from an opposing team with the opposing manager’s consent or may borrow a player from another team, also with the opposing manager’s consent. If the team’s 9th player arrives after the start of the game, the borrowed player reverts back to his team. 
• If the pitcher is removed, he may re-enter to pitch only one time during the course of the game, but not in the same inning. The removed pitcher may play any other position after being removed or no position at all. The re-entering of a pitcher can only be done once a game.
• No player may switch teams without the consent of league office and/or the both managers. In the event a team disbands during the season or at season’s conclusion, all players will become automatic free agents and will be permitted to play for any desired team.
• Pitchers may not wear white or gray sleeves, batting glove or wristbands. 
• Players that will need courtesy runners must have their manager notify the opposing manager and accepted prior to the start of the game. If not so notified, the opposing manager may deny the request. Each team will be allowed the pitcher and catcher a courtesy runner at any point at any time. The individual who runs for these player(s) needing a courtesy runner is not determined ahead of time. It is always the last batted out or a player on the bench who must run for the person needing the courtesy runner.
