1.Collision rule: A base runner must make every attempt to avoid a collision with a fielder. A fielder cannot block the base path without possession of the ball. A fielder more than 3 feet up the line without possession of the ball can be called for interference.
2.Games can end/result in a tie.
3.Bases will be 60 feet and the pitching plate will be 44 feet from home plate.
4.Any pitcher must be removed from pitching after hitting (3) batters in one game.
5.There is a continuous batting order. (All players must bat)
6.Each mustang player present must play three (3) complete innings, assuming the game is not shortened by the slaughter rule or weather. A substitute must play three (3) complete innings. The pitcher will not return to the mound.
7.There are no intentional walks.
8.If at the end of the season two or more teams finish with identical records, the higher place finish will be decided by regular season head to head competition. If the teams evenly split the regular season games then run differential between the two head to head games will be the next tiebreaker. If the run differential is tied, the next tiebreaker is runs against for the season. If the runs against is equal then a flip of a coin will determine the higher place finish.
9.If a batter, in the judgment of the umpire, unnecessarily tosses his/her bat, after making contact and hits a player or umpire, then the batter will be out and no runner will advance. The play will be dead. If the player makes no contact, the umpire will issue a warning.
10.Stealing home is not allowed. The only way the runner may advance to home from third base is by being batted in or walked in.
11.Runners may steal second or third base but may not leave the base they are occupying at the time of the pitch until the pitched ball has reached or passed the catcher. Once the pitcher has possession of the ball the runner must return to the base. Runners who leave the base before the pitched ball reaches or passes the catcher will be called out and the pitch will be considered a dead ball.
12.There will be no dropped third strike; the batter is out.
13.Prior to the first Monday in June, pitchers can pitch up to three (3) innings per game and a maximum of seven (7) innings per week. Starting the first Monday in June a pitcher may pitch up to a maximum of four innings per game. Innings per week will remain at seven. For the purposes of determining when a week begins and ends, the week starts on Monday at 12:01 AM and ends at 12 midnight the following Sunday.
14.Pitchers, after pitching three innings (before the first Monday of June) or four innings (starting with the first Monday of June) on the same calendar day, will have forty (40) hours of rest before pitching again.
15.If a player is hit by a pitch, the ball is considered dead and runners cannot advance.
16.On a walk, a player cannot advance past first base unless played upon.
17.No full inning will start after one hour and forty-five minutes. Time limits do not apply during playoffs.
