Minors AA Rules
Montgomery County Little League (MCLL)
2023 Local Rules
Baseball Minors AA Division
Ratified: February 26, 2023
MCLL will be governed by the rules set forth by “Little League Baseball Official Regulations, Playing Rules, and Policies”, also known as “The Green Book” unless noted and modified below. Please be familiar with the official LL rules. The rules below are primarily to help clarify common areas of confusion, emphasis safety rules or set a local rule that varies from a Little League rule. Rules related to safety, good sportsmanship and the proper teaching of fundamental baseball skills should receive the highest priority. All rules below apply to both the regular season and playoffs unless otherwise noted.
Each team must field a minimum of eight (8) players for a legal lineup. (Modification of LL Rule 4.16 and 4.17). With only 8 players the following positions must be utilized: C, P, 1B, 2B, 3B, SS, 2 outfielders.
Only players on the official league roster provided to the manager / head coach by the league commissioner are permitted to play in a league game unless assigned by Player Agent. (Summary of Regulation V)
If a team knows it will be short players for a game the manager can make a request to the Player Agent for fill-in players. The Player Agent maintains a list of eligible pool players from which the fill-in players will be drawn. (Summary of Regulation V)
The bat must be a baseball bat which meets the USA Baseball Bat standard (USABat) as adopted by Little League. It shall be a smooth, rounded stick, and made of wood or of material and color tested and proved acceptable to the USA Baseball Bat standard (USABat). (LL Rule 1.10)
Traditional Batting donuts are not allowed to be used. (LL Rule 1.10)
Any non-adult personnel occupying a coach’s box must wear a helmet. (LL Rule 1.16)
Helmets cannot be removed during play. After a warning the player can be removed for unsportsmanlike conduct. (LL Rule 1.16)
All male players wear athletic supporters while playing and are required to wear a metal, fiber or plastic type protective cup while playing catcher. (LL Rule 1.17). MCLL strongly encourages all players to wear protective cups regardless of position.
All catching masks must be outfitted with a “dangling” type throat protector” (LL Rule 1.17)
Shoes with metal spikes or cleats are not permitted. Shoes with molded cleats are permissible. (LL Rule 1.11.h)
C-flaps and other protective helmet attachments are permitted so long as the helmet is not altered in a manner that voids the helmet safety certification (NOCSAE certification). For example drilling holds in a helmet will void the certification, as may the addition of after-market third party C-flaps.
Home team will occupy the 1st base dugout and bench area.
Each team must supply a scorekeeper and pitch counter. The home team keeps the official book.
Teams are responsible for tracking their own pitch counts and removing players when pitch count limits have been reached. (See Pitching)
Each game shall consist of six (6) innings. (LL Rule 4.10a)
An official game shall consist of at least four (4) innings, 3 & 1/2 innings if the home team is ahead. (LL Rule 4.10c)
A team may only score five (5) runs per inning. After the 5th run has scored, that team’s at-bat is over. (Rule 2.00 - An Inning)
A 11 run mercy rule is in effectif after 4 innings, three and one-half innings if the home team is ahead, one team has a lead of 11runs or more, the manager of the team with the least runs shall concede the victory to the opponent.
A 6 run rule is in effect if after 5 innings, four and one-half innings the home team is ahead, one team has a lead of eight runs or more, the manager of the team with the least runs shall concede the victory to the opponent.
Teams may continue play if the time limit has not been reached, with any runs scored after reaching the mercy rule not counting towards the game total.
If the visiting team has a lead, the home team must bat in its half of the inning before the mercy run rule takes effect. (LL Rule 4.10e)
LL Rule 4.19(g) is invoked so that all game protests must be resolved before the next pitch or play. In other words, a game protest made to the board after a game may be reviewed for educational purposes, but will not result in the replay of the protested game, nor change the score or outcome of the game. (LL Rule 4.19(g))
Time Limits are a Local Rule and necessary due to time restrictions on field permits. The following are all Local Rule modifications of Regulation VII.h.
Time limits are governed by the time limit set in the official MCLL schedule.
Due to time restrictions on field permits, it is imperative that games start on time. If a game is not completed within the time limit, the determination of the winner follows the same rules as a game called for weather. (Modification of Regulation VII.h))
No new inning shall begin 1 hour and 45 minutes after the start time of the game and the game shall not extend beyond 2 hours minutes in total. If a shorter time limit is necessary, no new inning will start 15 minutes before the official end time and will be clearly communicated at the home plate pre-game meeting. (Modification of Regulation VII.h)
If the hard time limit of 2 hours has been reached the game will be called immediately. If an at bat is in process, the game will be ended upon completion of the current at bat. (Modification of Regulation VII.h))
Exception: During playoffs there must be a winner. Games will continue until there is a winner even if the hard time limit has been exceeded and extra innings are required.
For purposes of determining whether or not there is enough time to start a new inning, the actual start of a new inning shall be deemed the time at which the third out to end the prior inning occurs. In other words, the third out for the home team immediately triggers the next inning. (Modification of Regulation VII.h))
Called and Suspended Games:
Please see LL Rules 4.10, 4.11 and 4.12 for a full explanation of regulation, called and suspended games.
In the event of a called or suspended game, and the outcome is not clear or disputed, the Managers and Umpire shall submit a description of the exact situation for resolution by the Umpire in Chief and the Board.
All suspended games MUST be scheduled through the league.
A continuous batting order that includes all players on the team roster present for the game batting in order shall be used. (Variant of LL Rule 4.04)
When a player is injured, becomes ill, or must leave the game site after the start of the game, the team will skip over him/her when his/her time at bat comes up without penalty. If the injured, ill, or absent player returns he/she is merely inserted into their original spot in the batting order and the game continues. Also, if a player arrives late to a game site, if the manager chooses to enter him/her in the lineup (see Rule 4.01 NOTE 2), he/she would be added to the end of the current lineup. (Variant of LL Rule 4.04)
The on-deck position is not permitted in Little League (Majors) Division and below. (LL Rule 1.08 NOTE 1)
Only one player (the batter) is allowed to handle a bat at any time - the batter at the plate. All other players must remain on the "bench". An assistant coach or parent must monitor this requirement to avoid injuries. (LL Rule 1.08 NOTE 2)
Any player throwing a bat will be given a “player warning” for throwing equipment (each player will receive one warning per game). Any further action of throwing equipment will result in the offending player to be called out. If that player had put the ball in play (with less than 2 outs and other runners on) then it is a live ball and the defense may make a play to record an out. In such a case where one of the other runners was called out then both that runner and the offending player would be out.
Batters are OUT on a dropped 3rd strike. (LL Rule 6.05.b.2)
Runners may not take a lead and cannot leave the base until the ball has crossed home plate. (LL Rule 7.13)
The following restrictions on stealing apply.
Players may only advance one base (total) on an attempted steal.
Catchers should be encouraged to make a play on an attempted steal if there is a chance to throw the runner out.
A team may only have one successful steal of home per inning. Advancing home from 3rd base on an overthrow of a steal at 2nd base counts as a steal of home.
Head first sliding is not allowed and that player will automatically be called out.
Exception: Any player who has possession of a base may “dive back” into the same base to avoid being thrown out by a fielder making a play. (LL Rule 7.08.4)
There is no “must slide” rule. However, the runner is out when the runner does not slide or attempt to get around a fielder who has the ball and is waiting to make the tag. (LL Rule 7.08.a.3)
Pursuant to LL Rule 7.00(b) a "courtesy runner" shall be permitted for a player who is on base with two outs and is the designated catcher or pitcher in the next half inning. The courtesy runner will be the player that made the last out (i.e., the player that made the second out of the inning). No courtesy runner is allowed in the last inning of the game (i.e., the 6th inning or as may be designated by the umpire) or during extra innings.
Teams are allowed to use 10 players on defense by adding a fourth outfielder.
There is no infield fly (Modification LL Rule 2.00)
Playing Rule IV is modified so that each player must play at least three (3) innings by the end of the fifth (5th) inning of the game and must have played both an infield and outfield position by that point of the game. The Catcher position counts as an infield position.
A starting pitcher may stay in the game until their pitch count limit is reached and does not have to be removed from the mound in order to satisfy outfield play. However after leaving the mound that player must satisfy the outfield play conditions as applicable. This rule is intended to encourage player development but not easy to enforce, therefore coaches are encouraged to follow this rule with integrity. During the playoffs this rule is suspended.
No one player can play a single position for more than 3 consecutive innings. The exception is in the case of a pitcher who can remain until pitch count limits are reached. During the playoffs this rule is suspended.
Playing Rule 4.03(c) is modified such that outfielders must play approximately 20 feet or more beyond the base path which typically means that players must be stationed on the outfield grass. (Modification of LL Rule 4.03(c))
Infielders must start their defensive position within 5 feet of the baseline in which they are playing. (Modification of LL Rule 4.03(c)
Pitching limitations – Regulation VI regarding pitch limits MUST be adhered to. (See MCLL website for summary). A player's pitch count for the purposes of day(s) rest threshold is determined by the first pitch thrown to their final batter.
The pitcher’s mound is set at 43 feet from home. (Modification of LL Rule)
Any player who has played the position of catcher in four (4) or more innings in a game is not eligible to pitch on that calendar day. The catcher receiving one pitch to a batter in the fourth inning constitutes having caught four (4) innings. Warm-up pitches do not count. (Regulation VI.a)
Any player who played the position of catcher for three innings or less, and delivers 21 pitches or more in the same day may not return to the catcher position, except if a pitcher reaches 20 pitches while facing a batter, the pitcher may continue to pitch and maintain their eligibility to play catcher until that batter reaches base, is retired, third out is made, or pitcher is removed prior to the batter completing the at-bat. (Regulation VI.a)
A pitcher who delivers 41 or more pitches in a game cannot play the position of catcher for the remainder of that day, except if a pitcher reaches 40 pitches while facing a batter, the pitcher may continue to pitch and maintain their eligibility to play catcher until that batter reaches base, is retired, third out is made, or pitcher is removed prior to the batter completing the at-bat (Regulation VI.c)
Under no circumstances may a player pitch more than 3 consecutive days or more than one game in a day. (Regulation VI.d and k)
A pitcher is allowed eight (8) warm-up pitches between innings or one (1) minute, whichever comes first. An initial eight (8) pitches will be awarded to any pitcher entering the game. (LL Rule 8.03)
Managers and coaches are permitted under Little League rules to warm up pitchers if the catcher is not ready or when a bench player is not able to. Catchers or bench players wearing the proper face mask and a protective cup are encouraged to warm up pitchers. No pitcher will be allowed to wear long white or gray sleeve shirts. Neoprene sleeves, if worn by a pitcher, must be covered by an undershirt. Any pitcher doing so will be asked to remove the shirt or sleeve, or will be removed from the pitcher’s position. (LL Rule 1.11.a.3)
There are illegal pitches but no balks in this division. A pitcher shall receive a warning on his first illegal pitch. All subsequent illegal pitches shall count as a ball. (LL Rule 8.05).
If a pitcher hits three (3) batters “on the fly” (i.e. the ball hits the batter while in the air and without hitting the ground first) in one game, the pitcher will be removed from and will not be eligible to return to the pitcher position for the remainder of the game.
A manager or coach may come out twice in one inning to visit the pitcher, but the third time out, the player must be removed as pitcher. A manager may come out three times in one game to visit the pitcher, but the third time out the player must be removed as pitcher. 2 per inning, 3rd visit a removal; 3 per game, 4th visit a removal. (LL Rule 8.06)
Fall Rule Variations
Pitchers are restricted to two innings for a Fall Ball game. Fall Ball is developmental so coaches should work to develop more pitchers.
No score is kept, except for purposes of determining the end of a half inning as set forth under Local Rule 3.6. There is no run mercy rule. Fall Ball is developmental so the full time should be utilized to give players playing time. If a team is up by a large margin then that is an opportunity to allow other players to pitch.
