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.

Playoff Games
If the time limit has expired and the game is tied, the game shall be played in extra innings until a winner is determined. In championship games, all efforts will be made by DSB to have no time limit, but game schedules may not allow it. For championship games, DSB will communicate in advance to teams about a time limit or not.

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 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 for the Spring and Fall Rec program. 

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

Spring Middle School League
The DSB Middle School League uses pitch counts.

Number of Pitches Required Days Rest
1-20 0
21-35 1
36-50 2
51-65 3
66-95 4

A pitcher shall not throw more than 95 pitches in a single game. A pitcher shall not pitch in more than one game in a day. A pitcher shall NOT pitch in a game on three consecutive days, regardless of pitch count.

If a pitcher crosses a pitch count threshold during an at bat, and is removed after the completion of the at bat, the pitch count shall be "rounded down." Example: Pitcher throws pitches 35, 36, 37 and 38 during an at bat, but is removed after the at bat is completed, the pitch count total for the pitcher would be 35.

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. Coaches are required to use the PitchingRecord.xlsx sheet that is provided by DSB. Coaches can fill it out manually or use Excel (recommended). Pitchers who are ineligible to pitch should be marked with an "X".

Coaches should indicate what players are ineligible to pitch on the lineup card that is exchanged with the opponent.

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.

Lineup Cards
Coaches of each team shall exchange lineup cards at least 10 minutes before the scheduled start time of the game. The lineup card shall include complete and legible player information (batting order, player jersey number and player last name). An accurate and complete list of players who are not in the starting batting order shall be listed as well (player jersey number and player last name). This should be considered the official batting order and substitution list. Players who are not listed in the batting order or on the substitution list are not eligible to participate in that day's contest.

Warm-Up Catchers
Cup and mask required. This applies to on the field and in the bullpen.

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.

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.
