House League General Rules

In general, regular baseball rules apply. The individual rule sheet for each division is designed to promote fun, learning and safety.

General Rules for T-ball, 5-Pitch and Rookie Ball:

  1. T-ball games are a maximum of 1 hour. All Rookie Ball games are a maximum of 1.5 hours. All teams must be ready to play at the appointed starting time. No forfeit games, teams are to play short or share players if necessary.
  2. In addition to the volunteer coach, all teams require significant assistance to operate effectively. For example, a typical T-ball or Rookie ball team needs the following:
    • Coach to assist the batter
    • 2 base coaches
    • A person to line up the players waiting a turn to bat and keep track of the next batter due up
    • A person to assist the children in putting on the helmet and choosing a bat
    In total at least 5 individuals are needed to help out in some manner. Any parents with concerns about any aspect of the game (coaching, umpiring, etc) should be directed to contact the convenor.
  3. In T-Ball all players field each inning. Coaches must (particularly starting in T-Ball, Rookie Ball and Mosquito where players actually take infield positions) ensure that all players are receiving an equal opportunity to play on the infield regardless of capability.
  4. Tball and rookie ball do not keep official scores.  
  5. No formal standings will be kept in the youngest age groups. Rookie ball teams can keep score if they wish however no formal standings will be kept.
  6. A coach/manager may only communicate positive instructions to their players on the field.
  7. There is no need to argue with the umpires at all. Any difficulties with umpires should immediately be brought to the attention of the convener(s). The overriding concern is safety. There will only be umpires for senior rookie (9U) games.
  8. Umpires are learning the game as well. Our umpires are encouraged to make safe and out calls, and to call strikes. It is expected that the coach support our umpire's call and have players leave the playing field if they are called out on the bases or if they strike out. By allowing players to continue on the bases after being called out, it doesn't encourage defending players to attempt to make plays or to teach the offensive team the fundamentals of the game.
  9. Latecomers are placed at the end of the batting order. A coach may insert a chronic latecomer earlier in the lineup to avoid a player always being the last batter week after week. Please identify this to the opposing team. Continuous batting order.
  10. A player retiring from the game is skipped in the batting order without penalty, regardless of the reason.
  11. There is no stealing. Runners cannot leave a base until the ball is hit. All base running is to be reasonable in the circumstances. A ball hit on the infield gravel should be considered a single. If the ball is thrown "out of play" on a single (or any other play) then the runners all move up 1 base. A ball hit to the outfield may be a double or greater depending on the circumstances. For example on a ball hit immediately behind 2nd base, it is unlikely that the batter would be able to proceed to second base. A ball hit far into the outfield might be a clear triple or even a home run. In no case should running "wildly" be used to turn clear singles into triples or even home runs. Teams should also take into consideration the score when running. A more conservative approach is normally taken in a situation where you are winning by an insurmountable lead. There must always be a first and 3rd base coach on the field for the batting team and the head coach is to ensure the base coaches are familiar with this rule. This rule involves a great deal of discretion, but the main aim is to try and teach the runners a reasonable approach based on the assumption of good fielding. Overly aggressive base running may result in some form of punitive action at the discretion of the convener.
  12. All batters, runners, on deck batters must wear an approved helmet with a chinstrap done up. 
  13. Bat throwing is extremely dangerous and must be closely monitored by all coaches and umpires. Any bat that the umpire feels was in any way used or thrown hazardously must be pointed out to the coaches so that the child can be appropriately instructed. Repeated throwing may result in the umpire calling a batter out (i.e. 2 or 3 times same child, 2 or 3 times same inning).
  14. Home team sets up the diamond (bases, pitching machine, etc.)
  15. On any dead ball called by the umpire, runners advance to the next unoccupied base that they have not taken possession of.
  16. At all levels, players are to be encouraged to attempt to make plays (i.e. throw the ball to first, etc.) regardless of the outcomes.
  17. All umpires are being instructed to hustle the game along. Baseball can be a very exciting and rewarding experience if there is lots of hustle, few if any continual discussions, players are ready to take their field positions, back catchers are ready, batters are ready, helmets are on, and coaches are organized in advance.
  18. All players and coaches to wear uniforms supplied by STMBA (shirts and hats). 
  19. Cancelled games will be sent through the website.  All parents are encouraged to sign up to receive text or email messages.
