League Rules

NWAMSBL adheres to National League Rules in addition to the local addendum rules listed below.

  • MSBL (25+) teams will be allowed to have a maximum of 5 (five) players between the ages of 18 and 25 on their roster subject to review by the board. When an MSBL team plays another MSBL team, an under 25 pitcher is only allowed to pitch the FIRST four innings of the game in a 9-inning game or the first 3 innings in a 7-inning game. After the first four (9in) or three (7in) innings, a 25+ year old pitcher must be used.

    1a. 18+ Rosters. Per National MSBL rule 3.a, a player must reach the age of 18 in the calendar year of the season of play.

  • Managers and Players should conduct themselves in a sportsmanlike manner at all times. Game officials will only discuss calls with managers and not with players. The National Rules for conduct are very specific: A player or manager can and will be ejected at the game officials' discretion for abusive profanity, verbal abuse, objectionable demonstrations of dissent, rough tactics, physical attack, and consuming alcoholic beverages during the game, or being on or around the field in an intoxicated condition.

    NO ALCOHOL WILL BE ALLOWED ON THE PARK PREMISES.

    NO SMOKING WILL BE ALLOWED ON THE PLAYING FIELD OR IN THE DUGOUTS.

    Violators will be immediately suspended from participation.

    National League Rule 4.a: There will be no beer or alcoholic beverages permitted at the field before, during or after the game. The field refers to the general playing area and ancillary areas.

    Rules governing parking lot areas are subject to local law enforcement codes and restrictions.

  • When a manager or player is ejected from a game a fine of $25.00 and a minimum 1-game suspension will be assessed for a first time offense (per season). The fine must be paid to the league in order for a player to be reinstated. If a player enters a game without having served his suspension and paying his fine the game will be forfeited. All ejections will be reviewed by the board. The board will vote to determine if the ejection was warranted (resulting in a fine), whether or not the minimum 1-game suspension should be upheld and whether or not additional disciplinary actions are required in response to the player or manager’s objectionable actions. The board’s decision is final and will be voted on by all board members that were not participants in the game or members of the next opponent of the team in question.

    (second offense - minimum of 2-game suspension)

    (third offense - disqualification for the remaining duration of the season)

  • A. Notification and Eligibility:

    i. Managers must notify the opposing manager and the home plate umpire of any players who will need a courtesy runner during the home plate meeting before the game starts. The opposing manager reserves the right to refuse the use of a courtesy runner during the course of a game if not notified during this meeting.

    ii. Each team is allowed a maximum of two players per game who can be classified as needing a courtesy runner due to age (45 years and older within the calendar year) or for an agreed upon injury or health-related reason. This includes pitchers and catchers, regardless of the inning’s out count, if they specifically meet the age or health conditions for courtesy.

    iii. Mandatory Courtesy Runners for Pitchers and Catchers: After two outs have been recorded in any inning, pitchers and catchers who reach base must accept a courtesy runner without objection. This rule is specifically designed to help preserve the timeliness of the game, minimizing delays between innings. If a pitcher or catcher was designated at the start of the game for a full courtesy runner, they are eligible for a courtesy runner even before two outs are recorded.

    B. Procedure for Courtesy Runners:

    When a designated player reaches base, he must call time out; he will then be replaced by the last player who was officially out. If the last batted out is also listed as needing a courtesy runner or is already on base, the second to last batted out will run and so on down the line of prior batted outs. If no outs have been recorded, the last batter in the lineup will act as the last batted out.

    C. Injury During the Game:

    i. If a player becomes injured during a game and the maximum number of courtesy runners (two) have already been designated, a pinch runner must be used, and no courtesy runner will be allowed.

    ii. If a player becomes injured during a game and the maximum number of courtesy runners has not been met, a courtesy runner may be allowed with opposing team approval. If the approval is denied, a pinch runner must be used.

    D. Incorrect Courtesy Runner & Forfeiture:

    i. If the offensive team replaces the runner with the wrong courtesy runner and the opposing team protests before the next pitch, the original runner must run and the right to use a courtesy runner for this particular batter will be forfeited for the remainder of the game.

    ii. If the original runner inadvertently runs for himself and the opposing team protests at any point after the next pitch, the right to use a courtesy runner for this particular batter will be forfeited for the remainder of the game.

  • 10 Runs after 5 innings (this is the only run-rule in effect regardless of innings played)

  • No new inning will be started after 3:00 hours in a 9-inning game.

    No new inning will be started after 2:30 hours in a 7-inning game.

  • Pick-up players will be allowed only when a team does not have enough rostered players to field a team. Pick-up players will not be allowed to play the field while regular roster players sit the bench. Regular roster players must take precedence over pick-up players. Pick-up players will only be allowed to bat in that instance. Pick-Up players must be placed at the BOTTOM of the lineup regardless of their skill level. Pick-Up players shall not pitch in a game for that team unless approved by the opposing manager prior to insertion. Pick-Up Players should be provided a team uniform when possible. Opposing coaches must be notified of the presence of a Pick-Up-Player. Our local league encourages Pick-Up-Players in this instance so that game-play may occur. Teams are encouraged to recruit such players to become league members in good standing and may add such players to their roster with league approval. No player which has been previously barred from game play in the NWAMSBL may be used as a pick up player. Players must play in a minimum of 5 (five) regular season or local tournament games in order to qualify for local league playoffs.

  • A team must have 8 players at game time to legally start the game. If a team has less than 8 players at game time, the non-offending team will receive a forfeit win AND play a practice game unless rule # 7 is enacted.. Should a team only have 8 players, they will be assessed an automatic out each time the vacancy occurs in the batting order. These vacancies are to be placed at the end of the line-up and announced by the umpire as such. Any time a team can field only seven players or less, due to absentee, departure, or injury…a forfeit will result. This rule may be averted by enacting rule # 7 above (Pick-Up Players) with approval by opposing team. A pick-up player may come from the opposing team (encouraged) or from another team with a player to give.

  • Each team will be allowed 1 (one) intentional walk per game. An intentional walk will be announced, pitching out to the player is not a requirement.

  • If a pitcher hits 4 batters in any one game, the pitcher must be removed from pitching on the fourth hit batsman. That player may be inserted into any other position.

  • All batters, base runners, and on-deck hitters MUST WEAR APPROVED HEADGEAR. 2008 Rule Change: Coaches in coach's boxes must wear protective headgear (helmets). This rule is in compliance with the MLB rule change that will trickle down to all levels of play for 2008. Failure to comply with this rule may result in forfeiture of your insurance coverage.

  • BBCOR OR WOOD bats used must not exceed a ratio of minus 3 (-3 or "drop three"). Which is calculated by the difference between the length of the bat versus the weight of the bat. No metal bats exceeding 36” in length and/or a 2 5/8” diameter are permitted. (e.g., a bat that is 34 inches long must weigh at least 31 ounces (oz.) by factory standards). Any player detected using a bat out of these proportions will be declared automatically out. Wood bats may be used and are encouraged.

  • A team that is compelled to forfeit a game due to lack of players at game time will automatically be fined $100.00 to cover the cost of umpires for a full game (generally $100.00 for a 7-inning game) plus field usage fees (generally $25.00 per day shared) if necessary. If the forfeited game is the first of a double-header, then the second game may be automatically forfeited and a total forfeiture fee will be $150.00. If a 48-hour notice is given in anticipation of a forfeited game, a $25.00 rescheduling fee will be levied if the forfeiting team wishes to make up those games (opposing teams must honor a rescheduled date which shall be agreed upon by both teams and the league office). Forfeiting coaches must notify BOTH the opposing coach and the league President when a forfeit is pending. These forfeit fees will be due prior to the forfeiting teams next scheduled game. If the next scheduled game is the second half of a double-header, then fees will be due prior to the next week’s scheduled games.

  • Catchers MUST wear SKULL CAPS (or hockey-style masks).

    b. Catchers MUST wear a Chest Protector.

    c. Catchers MUST wear a Mask (either traditional or hockey style). Neck guard optional

    d. Catchers MUST wear Shin Guards (on BOTH shins) that include at minimum knee covers and ankle covers. Lobster guards, foot covers, and knee savers are optional.

    e. Catchers SHOULD wear a Cup (not enforceable, but highly recommended)

    f. Catchers mitt is recommended, but not mandatory
