2022 Mad Batters League Rules

2022 Rules


  1. All players must be 18 years or over, as of the playing year.

  2. Maximum 10 players on the field.  Four (4) must be females. 

  3. A 15-minute grace period is allowed at the start of the game, after that the game will be forfeited. 

    1. If you have 8 players, 2 of which are female, present at the scheduled game start time you must begin on time with no grace period. This would result in 2 auto outs. At any time, a female can replace an auto out upon her arrival.

      1. The rule of 3 male batters in a row still applies in this scenario. (See Rule #10)

  4. When a team does not have the minimum number of players at game time, they will be forfeited. (Score will be reported as 10-0).

    1. If the team is able to field a team for the second game, the game will be played at the normally scheduled time unless both teams agree to start the second game earlier.

  5. Teams unable to meet the minimum line-up requirements are still asked to arrive with however many players they have on time. The permits and umpire are paid for already, so we ask the field does not go to waste. Combine teams, have fun. Should a team choose to not show up, a fine of $100 will be levied. This is to allow the league to cover the cost of the umpire and the permit. No wins are awarded to a team until all fines are paid.THIS RULE SHOULD NEVER NEED TO BE USED!!

  6. Maximum of 12 batters on batting order (Not including subs)

    1. Subs are to be replaced once per game. Until a substitute has been made, the replacement player is unable to bat or field.

    2. Once a sub has joined the game, the replaced player is unable to bat or field again.

  7. The 12 active players on the batting order may be moved freely in and out of the fielding position but must always take their proper turn batting.

  1. Rainouts will be decided no later than 4:00PM on game days. Managers will receive notification only after we decide. We will always try to play the games whenever possible. Rainouts will only occur if we, as a league, are sure the field will be unplayable at game time.

  2. Mad Batters are not meteorologists, we will not know earlier in the day if the diamonds will be playable or not. Once we decide, we will notify the managers. (No reason to call or text us. As soon as we know, you will know.)

  3. On days when the league has decided to try and play, and the weather changes for the worse after 4:00PM, the umpire on the diamond will make the final decision on whether or not the games are rained out. On days such as this, it is up to each team to make sure they have their team present and ready to play to prevent them from forfeiting their games.

  4. Once a rainout is announced at 4:00PM, the games will be rescheduled. Never will the league change their mind after a rainout is announced and expect teams to show up on the diamonds that same night.

  5. Make-up games are played on off nights (Commonly Thursdays). We will give as much notice as possible to the teams, so they have a chance to notify their players.
