1.       Offense
a.       Batting Lineup
i.      All players may bat - the batting lineup can be more than 9 hitters. Players are allowed to only bat and elect not to play defense (DH/EH).
ii.      Players not listed in the original starting lineup at the beginning of the game may be added to the bottom of the batting lineup without penalty. (ex. Late Arrival)
iii.      Players not listed in the original starting lineup can be used as a pinch hitter and substituted for any player in the batting order (ex. Standard pinch hitter). However, if you elect to add a hitter to the lineup and NOT remove a substitute, the addition must be made at the bottom of the batting order.
iv.      Players forced to be removed from the batting lineup for any reason (injury, leave early, etc) can be removed without penalty, keeping the remaining lineup in order. If this player returns, they may be re-inserted into their original place in the batting order.

b.      Courtesy Runner
i.      Courtesy runners may be used for any base runner at any time for any reason. Remember, the purpose of using a courtesy runner is primarily injury accommodation, and is NOT intended to allow a team to improve its baserunning situation/ability.
ii.      Selecting the courtesy runner
1.       If utilizing a batting player as a courtesy runner, it must be the player in the batting order most-closely preceding the base runner being substituted for (ex. Last batted out, go up the batting order backwards until you reach an available player not currently on base)
2.       A bench, non-hitting player may be selected to serve as the courtesy runner
iii.      Courtesy runners may not steal bases or advance via “defensive indifference” (ex. a non-throw when 1st and 3rd are occupied). They may advance via wild pitch/passed ball. For the purposes of this rule, a pitch must leave the catcher’s dirt circle to be considered a wild pitch/passed ball. If a courtesy runner advances via what is statistically considered a stolen base/defensive indifference, time will be called, and the runner returned to their previous base.

c.       Non-rostered/non-league substitute players
i.      In the event a team is required to use non-rostered players to field a full team of 9, the team is welcome to utilize players from other SABL teams, as well as non-league players, on an exception basis. Non-rostered players must bat in the batting order after all regular-rostered players. Non-rostered players may continue to participate even if the team does eventually have 9 players or more.

2.       Defense
a.       Pitching
i.      A pitcher may pitch a maximum of 7 innings per game.
ii.      If a pitcher is substituted for and leaves the mound, he may not return to pitch. If a game is out of hand and a team runs out of pitchers, a player can return to pitch if both managers agree.
iii.      Non-roster substitutes are not allowed to pitch.

b.      Defensive Positions
i.      Free and open substitution for all 8 other defensive positions (non-pitcher) should be allowed at any time.
ii.      Players are allowed to only play defense, and not be listed in the batting order. (ex. pitcher only, designated fielder)

3.       Minimum requirements to start and complete a game (for the consideration of official stats and standings)
a.       Teams must have at least 7 roster players to begin and complete a game to have the game count towards official statistics and standings.
b.      Teams are required to provide at least 8 players in combination of rostered and non-rostered players.
c. Teams can request a 9th fielder from the opposing team if both managers agree.
d.       Automatic outs:
i.      If a team begins a game with 8 batters, the 9th place in the batting order will be an automatic out.
ii.      If a team begins a game with 9 or more players, but reaches a situation through loss or injury of only maintaining 8 batters, there will not be an automatic out and the batting order will just continue.

4.       Games will be 9 innings.
a. If after 5 innings a team is up by 15+ runs or after 7 innings up by 10+, the "official" game is over and all stats in GameChanger stop and the win is awarded to the team in the lead.  The managers then decide how they want to continue.  Make a gentleman's agreement - let guys pitch or catch that normally don't get a chance, play positions you normally don't get to, have a few players switch teams, bat opposite handed, etc.  Be creative and have fun with it - that’s what this league is about.  A 5 run limit is in effect for the remaining innings and no stealing is allowed. Umpires are expected to stay until the end of the game.
