Rules and Regulations

Eastern Baltimore County Over 40 Baseball League Playing Rules


Eastern Baltimore County Over 40 Baseball (O40BB) uses the Official Rules of Baseball as its base, with the following adaptations. The adaptations are for use at the start of a new season and any them. These rules have been O40BB sanctioned event where the promoter chooses to use distributed to members of the Umpires Association.

Note I: These rules apply directly to Regular Season and Post Season play.

Note II: The O40BB rules amplifications, exceptions and adaptations, updated as of Jan.31, 2019, supersede any other written copy of O40BB rules.

1.0 Rule interpretations, addendums

1.01 Strike zone:

O40BB encourages umpires to call a “full” strike zone as described in Official Rules of Baseball: “. . . that area over home plate, the upper limit of which is a horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants, and the lower level is a line at the hollow beneath the kneecap. The Strike Zone shall be determined from the batter’s stance as the batter is prepared to swing at a pitched ball.” O40BB notes: 1) Over home plate is strictly a judgment call for each umpire. 2) Batters who duck a pitch do not compress their strike zone.

1.02 Batters box:

Batters must keep one foot in the box during their at bat, with the following exceptions:

1.02a. When batter is driven out by a pitch or has swung at a pitch.

1.02b. Defense calls time out or pitcher is off the mound.

1.02c. Defense attempts a play or a wild pitch / passed ball occurs.

1.02d. Catcher leaves his position.

1.02e. Offense (or batter) is granted a time out.

1.02f. Batter fakes a bunt or assumes possible ball 4.

1.02g. When the batter is out of the box, he may not leave the dirt area around home plate except in the case of a substitution, a conference or an equipment problem.

Notes: The intent of this rule is to keep the game flowing. When a player is in violation of this rule, the umpire will ask that the batter return to the batter’s box – one warning per offending player. If the offending player does not return to the batter’s box (or if the violation is repeated), a strike will be called without a pitch being thrown.

1.03 Decoy tags:

Decoy tags, inducing a runner to slide unnecessarily, are prohibited. An offending player is subject to potential ejection, with the runner awarded at least one base or as many bases as he would have made without the obstruction. There will be no warnings.

1.04 Intentional walk:

Hitter may be waived to first base upon the direction of the defensive team manager, pitcher or catcher.

1.05a. Hit Batters:

Any pitcher who hits two (2) batters in one inning, or 3 total in a game, must be removed from the pitching position. He may continue to play offense and defense.

1.05b. Umpires are instructed to not grant first base to a hitter who makes no attempt to get out of the way of a pitch or leans into a pitch in an attempt to get hit. The umpire’s decision is based on his judgment, and a ball (or strike) will be called.

1.06 Clean Base Hit Rule:

An outfielder shall not attempt to throw a batter/runner out at first base when a batted ball cleanly reaches the outfield grass. An outfielder may attempt to throw a runner out at second, third or home when a batted ball cleanly reaches the outfield grass.

1.07 Courtesy Runner A courtesy runner is permitted at any time, for any player, for any reason. Courtesy runners are not permitted to run with the pitch (steal). The courtesy runner is NOT allowed to advance on any passed ball or wild pitch. If the courtesy runner runs during the pitch, the play is ruled "dead" and the runner is out and the pitch is not counted. Courtesy runners may only courtesy run once per inning. Exceptions to the Rule are as follows:a. there is a Full Count on the batter with a runner on first, first and second or bases loaded with 2 outs. The courtesy runner is allowed to run once the pitcher starts his motion toward home plate.

1.08 Pitching:

Pitchers can pitch a maximum of 4 innings. One pitch constitutes an inning pitched, even warm-ups. Once a pitcher is replaced he can’t return as a pitcher. He may play any other position. A pitcher that hits 2 batters in one inning or 3 total in a game, will be removed from pitching for the remainder of that game.

1.09 Limited Runs Per Innings Provisions During innings 1-6: A team may score a maximum of 6 runs per inning, There is no restrictions in the final 3 innings and can’t be changed for any reason. During innings 1-6 if a player hits a HOMERUN their score or any other will not count once we reach six in the official score book.

1.10 Players Playing Time:

All players bat the whole game regardless of playing the field. Players must be allowed 4 innings in the filed unless they choose otherwise. The Umpires do not regulate this; it’s up to the MANAGERS.

1.11 Infield Fly Rule:

The infield fly rule will follow Major League rules as it is stated. The rule itself is not the issue, it is the manner in which it is executed. A player (infielder) must be "camped" under the pop fly. Any excessive back-pedaling or erratic attempt by the fielder should not be ruled an infield fly automatic out. This note is strictly for the umpires to use as a guide when interpreting this play. The umpire should make this call and use his judgment.

1.12 Visit to Pitcher's Mound:

There will be a limit of 2 visits a manager/coach can visit the pitcher's mound before the pitcher is removed. Upon the second visit, the pitcher must be replaced with another. Pitcher's mound visit exceptions are the following:

a) Any visit to the mound, between batters, to discuss defensive strategy by the catcher or other infielders where the pitcher or other players do not relocate.

b) Any visit to check on pitcher's health with regard to injury or potential injury.

c) Other players cleaning cleats with tongue depressors or rubber spike cleaner pad during rainy/muddy conditions.

2.0 Safety on the bases

2.01 Runners should avoid collisions with defensive players fielding a batted ball (fielders are entitled to the ball, which includes a step-and-reach beyond the point of contact with the ball, until such time as the ball passes a fielder with an chance to field it).

2.02 Any player – offensive or defensive – who initiates intentional and/or malicious contact with an opponent shall be called out, if applicable, and be subject to ejection.

2.03 Illegal slides will result in the sliding player being called out and being subject to ejection.

2.03a. A legal slide is directly to the base (defined as player being within an arm’s length of the bag) on a straight line from the previous base. A slide may go past the base as long as it is not in the direction of (or makes contact with) the defensive player handling the baseball; any runner who deliberately slides into a defensive player away from a base is out and subject to both an interference call and ejection if contact deemed malicious.

2.03b An illegal slide is described as:

2.03b.1 barrel-rolling

2.03b.2 body blocking

2.03b.3 sliding with such momentum that it takes the sliding player into a fielder beyond the base.

2.03b.4 sliding out of the baseline and making contact with defensive player.

2.03b.5 pop-up slides where runner initiates contact with defensive player.

2.03b.6 sliding with spikes above the fielder’s knee. (Offensive players may not hurdle a defensive player attempting to make a play or to avoid a tag.) 2.04 A defensive player may not deny an offensive player any access to a base (or plate) without possession of the ball. Obstruction is the ruling: The runner is safe and a delayed dead ball shall be called to allow play to finish.

2.04a Catchers may not block home plate without possession of the ball. (Straddling home plate is considered ‘blocking’ the plate. Note: O40BB follows the 2018-established MLB guidelines and addendum on plays at the plate and strongly suggests catchers position themselves in front of the plate while awaiting a throw on a play at the plate and slide into blocking position once in possession of the baseball.)

2.04b If an umpire rules obstruction for blocking a base without the ball, the defensive player will be warned; a second warning may result in ejection.

2.04c If, in the case of a defensive player denying access to a base without possession of the ball, and the runner collides maliciously, the runner shall be declared safe on the defensive player-initiated obstruction, but will be subject to ejection from the game. The ball is dead.

2.04d if a runner initiates a collision with a defensive player attempting to make a play, it is offensive interference and the runner is out. If the collision is ruled malicious or intentional, the runner is also subject to ejection. The ball is dead on offensive interference.

2.04e Malicious contact is described as initiating contact with arms and/or elbows up or in front of the body, lowering a shoulder, use of forearm in the contact or an act in the judgment of the umpire that is intended to harm or injure another player. Malicious contact includes all elements of illegal slides.

3.0 Sportsmanship

3.01 Sportsmanship and adult attitudes must prevail regardless of level of competition. Umpires are requested to eject players before, during or after games for any of the following behaviors, considered to be unsportsmanlike:

3.01a Consumption of alcoholic beverages during a game. (While O40BB and its umpires cannot make judgments on sobriety, managers are requested to prohibit players who appear intoxicated or smell of alcohol from playing. Umpires will eject players who smell of alcohol.) (See Rule 3.02 regarding alcohol.)

3.01b Threats of physical intimidation of umpires, players or spectators, including any threatening physical contact.

3.01c Verbal abuse of umpires, players or spectators, such as profanity, name-calling, belittlement or excessive harassment.

3.01d Excessive profanity, defined as profanity that, in the umpire’s judgment, is audible in the stands, dugouts and area surrounding the field of play, regardless of intent.

3.01e Throwing of equipment (bats, helmets, gloves, etc.).

3.01f Fighting.

3.02 Alcohol:

Alcoholic beverages are prohibited at the playing sites – before, during and after all games. Playing sites are defined as the playing site itself plus the property owned by the same entity surrounding the playing site. This includes parking lots. Player(s) found in violation of open-container ordinances at playing sites are subject to a 2-game suspension. Exception: Within the fenced boundaries of any event facility where alcohol sales are permitted by law.

Smoking is prohibited on the field of play during games. Players who wish to smoke must go to the stands, dugout or the parking lot. Player(s) found in violation of tobacco regulations at playing sites are subject to ejection.

4.0 Game guidelines

4.01 Games:

All games are scheduled for 9 innings unless noted. Managers have the discretion to shorten the length of games due to weather or other logistical conditions that are beyond their control.

4.01b Time Limit: No new inning will begin after 3:00 hours of playing time in a scheduled 9-inning game. The exception to this rule is during the playoffs or tournament type play. The game will continue until there is a clear winner.

Special Notes:

It is each team manager’s responsibility to monitor time issues. Umpires are requested to notify both benches at least 1 full inning ahead of reaching time limits. Umpires will ‘stop the clock’ on a) weather suspensions, b) injuries where a player requires medical attention on the field, c) to handle protests, and d) any other unavoidable delay.

4.01c Weather issues: All games stop immediately when Lightning is visible. Weather-stopped! games are suspended pending the decision of the Umpire, regardless of number of innings played. (Umpires may suspend but not declare game over in weather situations.)

4.02 Extra innings:

Games where scores are tied at the completion of 9 innings shall go into extra innings provided time limits allow. See 4.01 for exception to rule.

4.03 Lineup cards: Both managers, prior to or at the home plate meeting at the start of the game, will give the opposing manager a copy of their lineup, which MUST include:

4.03a First Initial or first name and last name of all players who potentially could appear in the game.

4.03b All players (including all substitutes and relief pitchers) MUST be listed on the lineup card, even if they are not starting offensively or defensively, to be eligible to play in the game.

4.03c Umpires will be responsible for lineups during the game to handle eligibility questions, score book discrepancies and batting out of order issues.

4.04 Batting order rules:

The basic batting order is 9 hitters; there is no maximum. Batting order may not be reduced after the first pitch. All players must bat if the player chooses to hit. He is not required to play the field if he wishes. Managers should play his players in both offence and defense positions, if the player chooses.

4.04a Teams may start a game with 8 players; when ninth player shows up, he will be inserted into the ninth spot in the batting order without penalty.

4.04b If the batting or fielding contingent is fewer than 8 at any time, the game is ended with the deficient team forfeiting.

4.04c If a team begins play with 9-or-more players and all are in the offensive order (therefore, no substitutes available), and a player is forced to leave the game (offensive & defensive lineup) for an injury or non-ejection type of reason, no “out” will be declared when that player’s position comes to the plate. However, if the offensive player leaves the lineup for an ejection type reason, an “out” will be declared for that vacant spot in the batting lineup each time it comes to the plate. Notes: If a player is injured and out of the game, he is removed both offensively and defensively. If an injured player wants to hit in a 9-man scenario, he must also run or walk to first base.

4.04d Exception to the automatic out:

A game may not end on the automatic out.

4.04e Additional hitters may be added to the end of the batting order provided that ...

4.04e.1 players are listed on lineup card;

4.04e.2 offensive lineup may not be reduced at any time; exception being injury (see 4.04c above).

4.04e.3 team adding to its lineup must communicate addition to umpires and to opposing team/score book prior to that player hitting.

4.05 Defensive substitution:

There will be free and unlimited defensive substitutions without reporting to the umpire, the official scorekeeper (in playoffs) or the opponent’s scorekeeper (although it is a courtesy to do so). Exception: Pitching changes must be reported to the umpires and to both team’s scorekeepers.

4.05a Defensive players are not required to play offense, and offensive players are not required to play on defense.

4.06 Official Scorebook:

The home team scorebook is the official scorebook unless the home team concedes the responsibility to the visiting team and informs umpires.

4.07 Pre-Game meeting: Managers are required to attend pre-game home plate meeting. (In case of protests and/or ruling clarifications, umpires will discuss issues only with those who attended pre-game plate meeting.)

4.08 Protests:

Protests are allowed on misapplication of game rules. Protests on a judgment call by an umpire will be declined. Retroactive protests will not be accepted. Protests must be made at the point at which a rule has been misapplied. To protest a game, a manager must:

4.08a Stop the game before the next pitch is thrown.

4.08b Notify the umpire and the opposing manager that the game is being played under protest. 4.08c Write in the HOME team’s score book the situation and on what grounds the game is being protested. The protesting manager must sign the notations.

4.08d The umpire must sign the HOME team’s score book, noting the situation of the game (including the count on the hitter) when the protest was lodged.

4.08e Protesting team must write down reason of protest and give it to the plate umpire (who gives it to the Commissioner or event official addressing the protest).

4.08f Umpires and managers will meet with O40BB representative, or will contact either the Tournament Director or O40BB President (via phone if not on site) and resolve the protest before resuming the game. Decision of O40BB official is final.

4.09 Ejections:

Ejected players must leave the field of play and the vicinity of the playing field upon gathering their belongings. Any further contact with the umpires, even after the game finishes, could bring possible disqualification from the remainder of the event. All ejections carry automatic suspension for the player and require a written report from the umpire to be submitted to the Chief of Umpires and Tournament Director immediately upon completion of the game.

4.10 Ejection reinstatement:

Ejected players are suspended for the next game played by his club. Failure to do so will result in a team forfeiture and further disqualification. Any player ejected twice during the season, regardless of reason, is disqualified from further competition. Appeal: Any player ejected twice must file a written appeal for a hearing with the Commissioner and his Competition Committee. Decision of the committee is final.
