The basic rule is that a team cannot significantly improve the team by use of substitutes. 

1.  A team player that is not able to play a scheduled match must notify their team captain as soon as possible. The team captain is responsible for finding a suitable substitute.  If a suitable substitute is not available for a missing ‘b’, ‘c’ or ‘d’ player, the two players who are not the original computer generated 'a' roster player rotate end to end to fill that position. EXCEPTION: (Only in the case where the 'd' roster player on the team is missing, the team captain will designate one of the 4 player positions on the court as the position that player would be at if the player were present. At that position the 'b' and 'c' roster rotating players would play only one ball and then carry the other ball back to the other end.)  If the ‘a’ player is missing, any form of rotation is permissible. The original computer generated 'a' roster players are never allowed to rotate. If two players are missing, at least one substitute must be found or standard rules apply. A Mixed League team must have at least one man and one woman playing in a match.

2. Team captains when selecting substitutes must select from the substitute group list by choosing a player that is not playing that day in the same group as the missing player or from any group below that missing player's group. Players above that missing player's group cannot substitute.  Due to limited availability of substitutes for the Men’s & Women’s Leagues, if all the substitutes available in the missing player’s sub group  has been contacted and no comparable substitute is available , a player of the opposite sex may be called to substitute.

3. A person may substitute in a league that he/she is playing in if they are not scheduled to play that day, i.e., bye week players or eliminated tournament players can sub in their league.

4. Although husband and wife cannot be assigned to the same team, they can substitute on each others team or both can substitute together on another team.

5. New people who signed up and have been assigned a rating may be placed on a team or be placed in the substitution list. Permanent replacements for team members will be chosen by the committee.

6. Late arriving team players or substitutes may enter the game at any time between frames.

7. If a player is unable to continue playing for any reason, a substitute may replace the player between frames or games. A substitute can be asked to play 1, 2, or all games, however, if a substitute is playing and the missing  player returns before the match is over, the substitute cannot be replaced unless it was previously agreed to by the substitute. Once a player has agreed to substitute, another substitute may not replace the initial substitute without the initial substitute asking to be replaced.

8. The substitution list will be reviewed during league play and before the tournaments to correct for significant changes of playing skills.   Therefore, the up-to-date list on the website MUST be used when getting subs since players may be moved up or down in the groups during the season.

To view the up-to-date sub list, go to the website league roster and click on the word 'SUBSTITUTES' at the bottom of the team rosters.
