  • Playoffs - Quarterfinals and Semifinals: 1 hour and 30 minutes, no new inning after 1 hour and 15 minutes
  • Playoffs - Finals: 7 innings (no time limit), but mercy rule still in effect (12 runs after 5 complete innings or 4 ½ innings if the home team is leading)
  • Unless otherwise stated, the home team will be the team listed first in the schedule and will be the defensive team at the start of each inning.


  • A substitute player can only be used if the team has less than 9 players to avoid a forfeit, depending on substitute player availability. 🆕The substitute player can only play Back Catcher or Right Field, and must bat last.
  • Requests for substitute players must be made to the League Executive by submitting the “Request for Subs” Google Form by Friday 12pm preceding that Sunday’s game. The League Executive will contact the Substitute Players’ List and the spot will be given on a first come first serve basis.  🆕The appointed
    Substitute Player(s) must pay the one time $15 SPN/SPO fee online by Saturday 5pm to confirm their spot.
  • Subs must play in uniform. Captains will be asked to keep their spare team jersey in their team bag to provide to their sub player, and collect back after the game.
  • Sub protocol:
    1. The purpose of Subs is to prevent a forfeit, not to replace players
    2. Subs will only be granted to a team less than 9 players
    3. Due to a limited availability of subs, priority will be given to whoever submits a Request for Subs first
    4. The deadline for requesting subs is Friday noon. 
    5. We cannot guarantee any subs for any notices after the deadline. It is very hard to find Subs on short notice 
    6. It is important to communicate this deadline to your teammates, so they understand how last minute notices of absence can impact the team. 
    7. Subs will be confirmed after the Friday deadline and Captains will be notified of their sub for the week.
    8. Subs will bat last, but have no fielding restrictions. 
    9. Subs must play in uniform. Captains will be asked to keep their spare team jersey in their team bag to provide to their sub player, and collect back after the game.
    10. Once a sub is confirmed, they will be added to the line up. Missing player(s) that Sub was brought in for may not "rejoin" the game. 


  • A team must have a minimum of 9 players before a game may start. A 10 minute grace period is allowed from the scheduled start time to allow for the 9th player to arrive. During the 10 minute grace period, there will be no play and players are expected to stay in their dugouts.
  • A minimum of 9 players are required to field, otherwise a forfeit will occur (score will be 7-0).
  • The home team has the option of forfeiting home team advantage if they only have 8 players with their ninth player knowingly on the way to the game. If after 3 outs or the team goes through their batting order and the ninth player has not arrived, a forfeit will occur (score will be 7-0). The home team will not be permitted to force the visiting team with 8 players (with the ninth on the way) to take home field advantage, thus forcing a forfeit (For example, if the 10 minute grace period has passed, and the 9th player hasn’t yet arrived, if this team is the home team, they may switch to become the visiting team and start batting. If, by chance, in the first inning, the team goes through all 8 batters, and the 9th player is not there to bat, then the game is over and is deemed a forfeit. Otherwise, as soon as there are 3 outs, and the ninth player has still not arrived in time to take the field, a forfeit will occur).


  • The bench, dugout, coaching, and base coaching is reserved for only team members in uniform.


  • The home team takes 3B dugout and the away team takes 1B dugout.


  • All players participating must be on the lineup scoresheet and take a regular turn at bat, and must play a minimum of 2 innings defensively.
  • If there are any changes to the starting line-up, the team rep must submit the changes to the scorekeeper before the game.
  • Late arriving players (the 10th, 11th or 12th player) can be added to the lineup upon their arrival. They will assume the last position in the batting lineup if they have not arrived when it is their turn to bat. If the player does not arrive and their turn to bat comes, then they will not be able to play in the game.


  • If a player is removed from the game for an injury (as determined by the umpire’s discretion), they will NOT be declared an out. The player may not return to the game. However, if this reduces the number of players to below the 9 minimum, then the game will be declared a forfeit in favour of the non-offending team (score will be 7-0).
  • If the player were a base runner at the time they withdraw from the game, then a courtesy runner must be used to replace the player withdrawing.


  • If an injured player has to miss multiple games, after the 3rd consecutive game missed, their situation will be evaluated by the Resolution Committee for if/when they may be able to return and/or replaced. 
  • A player missing game(s) due to extenuating circumstances (illness, grief, etc) may be given special consideration at the League Executive's discretion.


  • If a player has to withdraw from the season because of an injury or personal reasons, a list of similar calibre players (based on assessments) to the player withdrawing will be provided to the Captains to select from.
  • The Captain and League Executive must ensure that the replacement player is at par with the player they are replacing, in order not to create an advantage or disadvantage to the team. While 100% parity will not be possible, due diligence must be done.
  • The replacement player would have a prorated number of games they will be allowed to miss in order to determine playoff eligibility. Our current missed game allowance is 5 of 13 games = 38%. The same percentage would be applied to the replacement player, according to the weeks left once they join the season.
  • Replacement players can be added to the roster up to, and including, the last regular season game.
  • Steps to replace players:
    1. Player withdrawing notifies captain
    2. Captain sends an email to notify League Executive
    3. Player withdrawing sends an email to notify League Executive
    4. eague Executive provide Captain with a list of lateral replacement players
    5. Captain and Co-captain choose a player from that list
    6. League Executive contacts chosen player to inquire if they are interested to join the season at a prorated fee determined by League Executive
    7. Replacement players sends in payment to confirm their registration



  • Intentional walks are not considered to be part of SSL values and are highly discouraged.


  • Each team shall be allowed a maximum of five (5) courtesy runners per game (no separate courtesy runners for players declared injured prior to start of the game). Courtesy runners can be used at any time after the batter has safely reached at least first base.
  • The intent of utilizing a courtesy runner must be made known to the opposing team and the plate umpire prior to an at-bat.
  • The same courtesy runner can be used more than once. If a courtesy runner is on base, and their turn to bat comes, another courtesy runner may take their place. This replacement courtesy will count as one of the maximum 5 courtesy runners per game.


  • There is a maximum of 5 runs per inning, with the exception of the last/open inning, which is unlimited runs (last/open inning is the 7th inning or as called by the umpire).
  • An open inning must be played to conclusion where warranted.
  • A game will be declared a mercy if a team is leading by 12 or more runs after 5 innings (4 ½ innings if the home team is leading) in both Regular Season Games and Playoffs.


  • All teams are responsible for keeping track of scores for their games. It is strongly recommended that the teams confirm scores between each inning. All game scores must be reported by the winning team to the Scorekeeping Committee. In the event there is a discrepancy between the winning team’s score and the Scorekeeping Committee’s score, the Scorekeeping Committee’s score shall be the official score card.


  • All players must plan to arrive for the start of the game during inclement weather, unless otherwise communicated by the League Executive.
  • Any games cancelled or stopped due to weather conditions will be deemed as a tie (score of 7-7), unless 4.5 innings have been completed. An inning is complete when the home team is up to plate. If the game is called off before the 7th inning is complete, then the score after the 6th inning will be used to determine the winner.


  • Teams who know in advance that they will be unable to field a team with a minimum of 9 players must submit a sub request form at least 24 hours prior to scheduled game time.
  • Any team which defaults the game without 24 hours notice to the League Executive may be subject to league fines. Game Default also includes failure to report to the park during inclement weather. Remember that there is another team who has arrived to play. 
  • If a team is in default, a Penalty fee of $25.00* may be charged by the league, and a recreational game will be played by the teams and available players. The umpire will stay and officiate. The default score shall be 7–0 in favour of the non-violating Team.
  • Should there be fines owing, they must be paid before the next game. Teams will forfeit any subsequent games for default fees unpaid. 


  • A game shall be declared a forfeit (score of 7-0) by the Umpire if the team:
    • a) fails to field the required number of players prior to or within 10 minutes of game time or after having gone through the batting lineup with just 8 players present;
    • b) refuses to continue the game after a suspension of play;
    • c) intentionally tries to delay or hasten the game;
    • d) intentionally violates a rule of the game after being warned by the umpire;

  • If both teams forfeit, the game will be declared a double forfeit (score of 0-0)


  • Any captain who wishes to register a protest on a ruling must verbally advise the umpire at the time of the Occurrence, record/mark down on the scoresheet that this is the case, and have it signed by the Umpire. The captain then has 24 hours after the scheduled start time of the game in question to formally register the protest in writing. All protests must be submitted to the Disciplinary Committee and accompanied by a written incident report and a $50.00* fee which will be refunded if the protest is upheld.

  • A batter shall be called out, on appeal, when failing to bat in his/ her proper turn, and another batter completes a time at bat in place of the proper batter. (1) The proper batter may take a position in the batter’s box at any time before the improper batter becomes a runner or is retired, and any balls and strikes shall be counted in the proper batter’s time at bat.
  • When an improper batter becomes a runner or is retired, and the defensive team appeals to the umpire before the first pitch to the next batter of either team, or before any play or attempted play, the umpire shall (1) declare the proper batter out; and (2) nullify any advance or score made because of a ball batted by the improper batter or because of the improper batter’s advance to first base on a hit, an error, a base on balls, a hit batter, or otherwise.
  • When an improper batter becomes a runner or is retired, and a pitch is made to the next batter of either team before an appeal is made, the improper batter thereby becomes the proper batter, and the results of such time at bat become legal.
  • When the proper batter is called out for failing to bat in turn, the next batter shall be the batter whose name follows that of the proper batter thus called out;
  • When an improper batter becomes a proper batter because no appeal is made before the next pitch, the next batter shall be the batter whose name follows that of such legalized improper batter.

  • Infield fly rule (IFR) is in effect when there are runners at first and second base, or if the bases are loaded with less than two out. In these situations, if a fair pop-up is hit that, in the Umpire’s judgement, is catchable by an infielder with ordinary effort, the batter is out regardless of whether the ball is actually caught in flight. To invoke the rule, the umpire will announce “infield fly” when there is a pop-up in the infield. IFR does not apply to line-outs or fly balls in the outfield. IFR does not apply to foul balls.

    • One (1) point for a tie
    • Zero (0) points for a loss
  • If two or more teams are tied at the end of the regular season, the tie(s) will be broken with:
    • Results of only the games between all teams tied, based first on their won/lost record; and if that fails  to break the tie,
