All softball teams are required to have a minimum of 15 players. If you and your crew don’t have a full roster, we’ll merge you with another small group.

First and foremost all Social Boston Sports leagues are 50% Social and 50% Sport. We do have officials; however, we expect individuals to respect the league’s culture of fair and fun play. Foul language and rough play will not be tolerated and individuals who cannot adhere to our standards of fair play and sportsmanship may be asked to leave the league. Social Boston Sports wants everyone to have a fun and be social while enjoying a great sport. SBS will do whatever it can to make sure all players are having fun.
Our primary mission is to make it easy for people to have fun and get involved with social sports and our different methods of registration help accomplish that goal. Because of these different methods of registration, all registrations are on a first come first serve basis and any roster that does not reach our standard size (based on each sport) is eligible to receive free agents and or small group by the league. Rosters made up of primarily free agents and or a collection of small groups may field more players than the standard roster size. This policy is in place to help ensure free agent teams are able to consistently field teams each week.

A “strike mat” will be used to determine sure strikes, if the softball touches any part of the mat OR home plate on a legal pitch (6’-12’ arc), it will be considered a strike.
All batters will start with a one ball, one strike count.
- If a male is walked on three (3) straight balls with two (2) outs on the board, and a female follows him in the batting order, the female has the choice to take a walk or bat.

He/she must keep all games on time in fairness to teams playing later hours and due to facility permit restrictions.
- Teams may bat more than ten (10) players. Prior to regular season games, teams must request lineups sheet in order to raise lineup objects during the game. For tournaments the umpire will require a line sheet.
- All players in the field must be listed in the batting order. Players do not have to play in the field in order to bat. Rosters/Lineups will be checked in playoffs.
- Games start on time! Teams must be prepared to play.
- Forfeit rule: 10 minutes after game time. If one team has less than the minimum number of players (7 total – 2 females) at ten past the designated start time, the game will be deemed a forfeit.
- Social Boston Sports will provide all bases and a balls for each game. Gloves are not guaranteed to be supplied and players must bring their own. It is also recommended that teams bring their own bats though at least one approved bat will be provided. (In Leagues that are marked as Wooden Bat Only the League will provide such bat!
- NO METAL SPIKES ARE ALLOWED.
- Any equipment in question should be brought to the attention of the umpire. The umpire will make all final decisions with regard to equipment discrepancies.
- During the playoffs, teams may not use subs and may only use players on their roster.
- Playoff Eligibility: teams that notch 2 or more forfeits during the regular season will not be eligible for the playoffs
- All thrown balls are deemed out of play when:
- The ball is thrown over the fence / road.
- The ball is thrown beyond the fence / road / safe area of play.
- The ball is thrown beyond the imaginary line extending from the End of the backstop (if there is no fence).
- This imaginary line applies to overthrows and caught fly foul balls.
- If the ball is overthrown and hits the fence behind the 1st or 3rd base lines, this is NOT considered out of play and the runner may advance, BUT at his/her own risk.
- On overthrows out of play, the runner is granted the base he/she is going to (at the point of the throw) plus one more. Note: in cases where a base runner runs past first base, he/she must make a clearly aggressive turn towards second base to be granted 2nd and 3rd in overthrow situations.
- Batting order must consist of a 3-1 ratio. (For every 3 male batters in a row a female batter must be next, ie. every fourth batter must be a female.
- Females can bat multiple times in the lineup to achieve this ratio.
- If females are batting more than once in a lineup their rotation must be stay in order. All females must evenly rotate through the female batting positions.
- In order to ensure all players are able to bat females may “double up” or rotate through the required female slots as described above.
- Game mercy rule: 15 runs up after four complete innings – losing teams option.
- Inning run limit rule: There will be a five (5) run limit per inning for all but the final inning which will be declared by the umpire.
- No lead offs or stealing, runners can leave the base once the ball is hit by the batter.
- If a runner leaves early, the ball is dead and the runner is declared out.
- If this is the 3rd out of the inning the batter will be first up in the next inning
- On an infield fly (any fly ball within the infield with significant arc and deemed an “easy catch”) with less than 2 outs and runners on 1st and 2nd or 1st, 2nd and 3rd, the batter is automatically out and runners can advance, BUT at their own risk.
- Base runner to defensive player contact will be closely watched by the ump.
- Any excessive contact or collision will result in an “out” and/or ejection. This includes contact with the catcher. Sliding is allowed. Any intentional (in the eyes of the monitor) interference with the defensive player, the runner and the batter will be called out.
- For plays between 3rd and home there is no contact allowed. When a runner passes the “commit line” (the halfway point between third and home which will be at the discretion of the ump), they can be called out at home if the defense gets the ball to the ”safety home plate” first. If the runner retreats to 3rd, and the defense gets the ball to 3rd before the runner, then they are also out on the force.
- The catcher or any defensive player playing as catcher must play the ball on the Defensive home plate (the original home plate). When the catch is made and the player is in this position the umpire will consider this moment as contact with the player or base.
- Any runners coming home must cross the Offensive home plate (slightly to the left side of home plate on the 3rd base side) before this mark is reached by the defensive player. If contact is made the player will be declared safe automatically.
- Additionally, any runner that touches the Defensive home plate rather than the Offensive one will automatically be called out.
- All plays between home plate and first base are force plays. There is no contact allowed on these plays. If contact is made with the runner, the runner will be ruled safe. If a runner “rounds” first and heads for second the runner can be tagged out.
- The strike mat is an extension of home plate and must be used by the runner for any slides / home plate crossings for safety purposes.
- All batting count starts at 1-1 (One ball, one strike).
- No bunting.
A Pitch has to have a slow pitch arch at least 6 ft. and no higher than 12ft off ground at its highest point to be considered a legal pitch.
- If a rainout occurs while a game is in progress, three (3) innings must be completed for the game to count. The umpire clock is the game clock and will inform both teams when the game has started.
- Games ending before the three (3) innings have concluded will be rescheduled and played as a new game.
- 6 innings or one hour of play, whichever comes first.
- In the regular season games can end in a tie. In the playoffs we will play extra innings, after the first extra inning each team will be required to pull a player off the fiend on defense. Each additional extra inning teams must pull a subsequent player off until they are left with 7 players (5 men – 2 women).
