Dunwoody Senior Baseball (DSB) provides a high quality, organized opportunity to play baseball for players ages 13 and up in the Dunwoody, Georgia area.


DSB Playing Rules

Unless specified below, all GHSA rules apply.

The Ballfields at Brook Run Park are synthetic turf.

Metal cleats are NOT allowed. Players wearing metal cleats will be ejected from the game.

Seeds, Peanuts & Gum
No sunflower seeds, shelled peanuts or gum allowed on the field or in the spectator area.

Players or spectators who use seeds, shelled peanuts or gum at the Ballfields at Brook Run Park will be ejected from the game.

The use of tobacco products on the field or in the spectator area is prohibited.

Plate Umpire is the Umpire-In-Chief for the game and in full control of the game.  This includes the authority to eject players, managers, coaches, and spectators from the game, the field, the stands or even the park if necessary to ensure the orderly conduct of the game.  Other responsibilities include:

  • Starting and finishing time for the game including expiration of time limits
  • Acceptability of equipment used in games
  • Number of warm-up pitches in excess of 4 between innings or for new pitchers.
  • Whether a player is in uniform.  Players must be in complete uniform, shirts tucked in.  No jewelry.
  • Whether a game is to be called on account of darkness, inclement weather, or field conditions once it has started
  • All judgement calls
  • The Plate Umpire’s decision in these matters is final and not subject to protest.


Normal Length
No inning starts after 2:00 hours.  Once started, innings are completed unless winning team has been determined.  If time has expired and the game is tied, the game ends in a tie.  If time remains and the game is tied, the game continues until a winner is determined or time expires.  In the event of a delayed start due to bad weather, the DSB Officer of the Day may shorten the scheduled duration of a game.

Start Times. 
The first game of the day will be considered to have started at the scheduled time unless bad weather requires field preparation or if the umpires are late.

Rain Delays
In the event of a significant rain delay, the clock will continue to run.  If more than 15 minutes were lost due to weather, the inning the game shall be official if 4 innings have been played (3.5 if home team ahead).  If last inning cannot be completed, score reverts to score at end of prior inning unless home team was batting.  In this case, score will be whichever score that is most favorable to home team.

Deliberate stalling on the part of any team is unsportsmanlike and not a part of the real game of baseball.  The umpire may allow an additional inning of play if in the umpire's judgment the other team was deprived of an opportunity to win the game because of stalling.
If games are behind schedule, scheduled game time for the following game will be 15 minutes after the end of the previous game.

Slaughter Rule
10 runs after 5 (4.5 if home team is ahead) and 15 runs after 3 (2.5 if home team ahead)


Spring & Fall Rec Leagues
DSB uses innings pitched versus pitch count for the Spring and Fall Rec program. The Rules are quiet simple.

  1. Pitcher may pitch 3 innings in a game.
  2. One pitch is equal to one inning.

Spring Middle School League
In accordance with the GHSA and NFHS, the Middle School League uses pitch counts.

Number of Pitches Required Days Rest
1-24 0
25-44 1
45-64 2
65-90 3

A pitcher shall not throw more than 90 pitches in a single game or cumulative over a two-day period. A pitcher shall not pitch more than two consecutive days regardless of the pitch count, at which time a minimum 1-day rest period is required. Double headers are considered two separate games and single game pitch count limitations are in effect. All other rest periods are based on the total pitches throw.

If limit reached during an at-bat, pitcher will be allowed to finish the at-bat.  Note this applies only to the 90 pitch limit. In order to be able to pitch the next day, the pitcher cannot pitch more than 24 pitches, no matter where in at-bat they are.

Coaches or designated scorekeepers are responsible for keeping pitch counts during the game.  Teams should regularly ensure that counts are correct with the other team.  In the event of a discrepancy, the home team count is the count of record.

Coaches will maintain records of pitches thrown and have these available at all games.  These should be shared prior to the game with the other team.  You are required to use the PitchingRecord.xlsx sheet that was sent to all coaches.  You can fill it out manually or use Excel (recommended).  Pitchers who are ineligible to pitch should be marked with an "X".  

Note that many of our players also pitch on other teams such as a travel team or an NYO team. You should be aware of any pitching for their other teams and always error on the side of caution.


Spring & Fall Rec Leagues

A team should hit everyone in their batting order.  If you’re carrying more than 12, you can hit 12 or everyone but each player must bat at least once during the game. This rule does not apply to teams that registered as a whole team for the league, meaning those teams can choose to bat 9 and are not required to get every player a plate appearance.

Outs are NOT taken if a team has fewer than 9 players available for the lineup. 

Free substitution in and out of the field. Players not in the batting order may field.

Middle School League

A team with 10 or more bats 10 (no more or less). None of the batters have to play the field. Outs are NOT taken if a team does not have 10. If a player goes out of a batting slot, they have to go back in the same slot if they come back in. Teams are not required to get every player a plate appearance.

Free substitution in and out of the field. None of the fielders have to bat.


Base Running        
Courtesy Runner. A manager may use a “Courtesy Runner” when the catcher or pitcher becomes a runner.  The Courtesy Runner may be one who is not in the batting order or, if all players are in the batting order, the player who made the last batted out.

A player may not serve as the courtesy runner for both the pitcher and catcher in the same inning.

Safety Rules   
Sliding Required. Runners must slide when there is a play while advancing to a base (other than 1st) or they will be called out. Runners will not be called out if there is no collision or incidental contact with the fielder. 

If a runner attempts to bowl over a fielder, the runner will be ejected from the game.  If a runner bowls over a fielder and knocks the ball loose, the runner will also be ruled out.

Warm-Up Catchers
Cup and mask required. 

Warm-Up Pitchers
Teams warming up a pitcher down the foul lines must provide a player with a helmet or an adult to protect the warm-up pitcher and catcher from batted balls.

Coach on Field
One defensive coach is permitted on the field, but must remain within 6 feet of the dugout.

Batting Cages
Teams may use batting cages prior to games. All batters must have a helmet and only an adult 18-years old or older is permitted to pitch.


Spring & Fall Rec Leagues

Upper League

  • All bats must be BBCOR certified (-3), consistent with GHSA and NFHS.
  • One-piece wood bats are permitted.
  • No unmarked metal bats are allowed.

Lower League

Middle School League

  • 8th Graders in A-Division must use a BBCOR bat. 
  • 8th Graders in B, C and D-Divisions must use a USA Baseball bat stamped bat, -5 or higher 
  • 7th Graders in any of the divisions must use a USA Baseball bat stamped, -10 or higher.


The intentional throwing of any bat, helmet, or other equipment shall be grounds for immediate ejection from the game.

No manager or coach may use tobacco, alcohol, or any illegal or controlled substance at or near the fields or dugouts. 
Any manager or coach ejected from a game will not be permitted to coach during the following game.

No manager, coach, player, or spectator shall engage in any conduct deemed inappropriate or detrimental to any player or coach at any practice or game.  This would include profanity, physical intimidation, derogatory comments, or any other conduct in the judgement of the Umpire or Board of Directors deemed inappropriate.  If such action occurs during a game, the umpire may issue a warning and shall take such action as necessary to stop the inappropriate conduct including ejection of person from the game, dugout, the stands, or the facility.

Game is forfeited if a team does not have 8 players at start or at any point during the game. If neither team has 8, then both forfeit. Managers may NOT agree to cancel or reschedule a game.

When a team is playing with eight players, an out is NOT taken for the missing 9th/10th batting slot.


One Manager or Coach may, after timeout is called and with the permission of the Plate Umpire, approach either umpire for purpose of discussing a disputed call. The discussion must be mild and brief. 

If a Manager believes a Game Umpire has misinterpreted a playing rule (as opposed to judgment calls, equipment, field conditions, time expiration and the like), he has the right to protest the Umpire’s decision.  He must announce his intention to protest before the next pitch is thrown.

Protest Resolution
Umpires shall halt play and try to resolve the protest with the Duty Officer and both Managers. If agreement is reached, the protest shall be considered withdrawn, even if the ruling is later determined to be incorrect.

If the facts are agreed to but agreement cannot be reached, the Head Umpire, League President or Executive VP if present may be contacted for a ruling. If none are available, the coach may protest the game. The protest must be stated prior to the next pitch being thrown.

The League must be notified by email immediately at the end of the game.  The league will issue a ruling when the facts are presented by the coaches and the umpires.

If the weather is bad, DSB will make every effort to notify coaches and close the field on the DSB website. The new synthetic turf fields drain very quickly, so teams should plan on playing, even if it is raining. Our goal is to give a 2 hour notice in advance of the scheduled time of play.
