All spectators and players not currently in the field must remain behind these lines at all times.

3.11. Foreign substances may not be placed on or in the ball.
3.12. If a ball has a crack of 1/4" or more, it will be removed from play.

4.00 - Game Management [top]
4.01. All regular season games will be part of a doubleheader. Prior to each doubleheader, the team captains will participate in a coin toss. The team that wins the toss may choose to be the home team in either the first game or the second game. Each team will be home for one of the two games.
4.02. Prior to the first pitch of every game, these four events are to happen in order:
a. Home team declares its starting pitcher
b. Visiting team declares its starting pitcher
c. Visiting team declares its batting order
d. Home team declares its batting order
4.03. Games are six innings long and each team gets three outs per inning. Extra innings will be played when necessary; there is no limit to the number of extra innings that can be played as long as the game remains tied. All games will be played to the full six innings unless called due to mercy or forfeit.
4.04. If a team is ahead by fifteen runs following the completion of the third inning, or ten runs following the completion of the fourth or fifth inning, the game will be called due to mercy. If the home team reaches the number of runs needed for mercy, the game ends immediately.
4.05. Players shall not unnecessarily delay the game.
4.06. The batting team shall always be responsible for “catching up” for the pitcher unless all members of the team are either batting or on base.
5.00 - Umpiring [top]
5.01. The count consists of up to four balls and three strikes.
5.02. Balls and strikes will be determined by the strike zone placed behind home plate. Any pitch that hits the front plane of the zone or clips its side in flight shall be called a strike.
5.03. There is no limit to the number of foul balls that can be hit with two strikes.
5.04. If a batter with two strikes hits a foul ball that then hits the strike zone in flight, the batter is charged with a strikeout.
5.05. If a batter is hit by a pitch, first base is not awarded.
5.06. If a batter moves into the path of a pitch that has a chance to be a strike or is hit by a pitch while obstructing the strike zone, batter interference will be called and a strike recorded.
Note: As long as the batter does not appear to be obstructing the zone prior to the pitch being thrown then he/she shall NOT be expected to move out of the way to allow a curveball to hit the zone. If a curveball that may have hit the zone hits a batter before curving in, then it shall be declared a ball.
5.07. If a batter touches the ball while making an attempt to catch a pitch, it shall be called a strike, regardless of its location.
5.08. The foul arc is treated like the foul lines. If the ball is touching the arc, it is fair.
5.09. Judgment calls can be made by anyone who saw the play, including the players. In the spirit of fair play, players are expected to be honest when making calls.
6.00 - Pitching [top]
6.01. The pitcher's back foot must be touching the rubber for the duration of the pitch.
6.02. There is no penalty for a balk. However, if a pitcher balks they must pause and give the batter time to reset before throwing a pitch.
6.03. A 70-mile-per-hour speed limit is in effect for all games. If a pitch is clocked at 71 or 72 miles-per-hour, then the batting team shall have the choice of no-pitch or the result of the play. If a pitch is clocked at 73 miles-per-hour or higher, then the batting team shall have the choice of a ball or the result of the play. If contact is made on a pitch over the speed limit, the person operating the radar gun shall wait until the conclusion of the play before saying anything. Operating the radar gun will generally be the responsibility of the batting team. However, anyone associated with the league is permitted to gun and enforce the speed limit rule. A pitch clocked over the speed limit can never result in a strike.
6.04. The starting pitchers (prior to facing their first batter) and new pitchers entering the game may throw up to twelve warm-up pitches from the mound. Pitchers may also throw up to three warm-up pitches upon taking the mound for the beginning of their half of an inning.
6.05. The declared starting pitcher may not be removed from the game until he/she has either completed the first inning or pitched for six complete plate appearances.
6.06. A pitching substitution must be declared official before a relief pitcher can throw warm-up pitches on the mound. The entering pitcher must also face at least one batter.
6.07. Once per game, a team may re-enter a pitcher who had previously been removed, as long as he or she did not throw a pitch in any of the batting team's previous six plate appearances. However, he/she cannot record a hold or save.
6.08. A pitcher who enters at the beginning of the fifth inning or later is considered a closer.
6.09. A pitcher may not pitch in both games of a doubleheader unless used as a closer in both games.
6.10. No pitch may be delivered while another ball is in the field of play.
7.00 - The Lineup [top]
7.01. The batting lineup must consist of a minimum of four players and may contain up to nine players.
7.02. A new player may be inserted at the bottom of the batting order just prior to the top of the second, third, or fourth inning (not between half-innings). After the commencement of the fourth inning, a new player may not enter the batting order except as an official substitution.
7.03. A player who is substituted for in the batting order may only re-enter the order in the same spot that they previously exited.
7.04. A player may re-enter the batting order only once per game.
7.05. If a player leaves the batting order without being substituted for, then the vacated spot shall count as an automatic out for the remainder of the game unless the player exited the game due to injury.
7.06. Upon request, the official scorekeeper is to tell the batting team which player is up to bat.
7.07. For a batting out of order call to be made, the fielding team must first wait for the improper batter to finish their plate appearance. After the plate appearance is over but before the next pitch is thrown, they may make a batting out of order call. If the call is correct, then the previous plate appearance will be recorded as an out and the appropriate batter will take their turn at bat. The out will be charged to the team and not a specific player. If, in the middle of an at-bat, the batting team realizes that the wrong player is up to bat, then the correct batter continue the at-bat and the fielding team may choose to either keep the count as is or reset it to 0-0.
7.08. Including the pitcher, no more than five players are allowed to play the field.
7.09. A team cannot bat four players in the lineup but still field five.
7.10. There is free substitution in the field; players are eligible to pitch and play the field at any time, even if they are not in the batting lineup.
7.11. A team cannot legally take the field with fewer than four players.
8.00 - Batting/Fielding [top]
8.01. Bunting is not permitted. If a player makes fair or foul contact on an attempted bunt, the play results in an automatic strikeout for the batter.
8.02. All defensive players must remain behind the pitcher's mound until the pitch is thrown, with the exception of the catcher, if one is utilized.
8.03. The fielding team may decide to use one of their fielders as a catcher. The catcher must remain directly behind the strike zone until the batter makes contact with the ball. A pitch fouled back over the top of the zone will be considered a pop-up, which can be caught for an out, while a pitch fouled back below the top of the zone will be considered a foul tip.
8.04. Plugging is permitted.
8.05. A player who is plugged above the shoulders while running normally and within the baseline is not out.
Note: Running normally means the runner did not jump, duck, dive, slide, or otherwise move their head into the path of the ball.
8.06. When making a tag, the hand or hands containing the ball shall be treated like the ball itself, as long as the player has complete control of the ball when the tag is initiated. If a player drops the ball while making the tag, the runner is still out.
8.07. Once a part of a base runner’s body has touched the ground on or past the commit line, that runner is committed to going home. When a runner is committed to going home, the fielding team may tag or plug the strike zone in order to get the runner out. If this is done successfully, the ball is immediately dead. Runners who were legally advancing to a base other than home and were more than one-fourth of the way to the next base, as well as runners who are forced to advance, shall be permitted to advance.
a. If there is a force play at home, this can be done regardless of whether or not the runner has crossed the line.
b. If a runner passes the commit line after leaving the base early on a caught ball, they may attempt to return to the proper base, but the fielding team may still attempt to tag or plug the strike zone (with the dead-ball aspect of the rule still applying) until the runner has returned to the proper base. If the ball is thrown out of play in an attempt to hit the zone and the runner has not yet returned to base, the runner shall return on his/her proper base and shall not advance further. A runner who was standing on first or legally advancing to second may advance if the base is open.
8.08. Once a fielder is in possession of the ball with both feet planted within the dead ball circle surrounding the mound and no runner is making a clear attempt to advance, the play shall be declared dead. A runner may still attempt to tag up on a ball caught within the circle as long as the attempt is immediate. A runner may also attempt to advance beyond the base that they are currently attempting to advance to as long as they round the base in stride.
8.09. When the ball is in play, a fielder may not use any object such as a hat or glove to assist in fielding the ball. If the fielder does so and the ball is fair or potentially fair, all runners who were on base will score and the batter will be awarded third base. The official scorer will determine if a single, double, or triple shall be recorded. If use of the object may have prevented the ball from going over the fence, then a home run shall be awarded.
8.10. If a fair ball rolls or bounces past the out of play lines, or beyond the fence -- even if in foul territory -- a ground rule double shall be awarded.
8.11. Any fair batted ball that strikes a pole used to support the fence shall be ruled a home run if the entire ball strikes an area of the post that is above the fence. If a part of the ball strikes an area of the post that is below the fence, the ball is in play.
8.12. The intentional distraction of another player through the use of any sounds or gestures is not allowed. If a member of the fielding team intentionally distracts the batter, then the same protocol is followed as for a 71 mph pitch. If a member of the batting team intentionally distracts a fielder, then the batter or base runner, depending upon which is more appropriate to the situation, shall be ruled out and no runners shall advance unless forced.
8.13. Foul territory is unlimited in regards to catching a ball in flight and runners may still tag up on any caught foul ball.
8.14. When covering first base, the fielder must attempt to remain on their half of the base. If it becomes apparent that there is not going to be a play at first, the first baseman must stay out of the baseline between first and second, in case the runner attempts to advance to second.
9.00 – Base Running [top]
9.01. Leading and stealing are not permitted.
9.02. If a runner is off base when the batter makes contact with the ball, they are immediately ruled out.
9.03. When a ball is thrown out of play, runners who were not attempting an advance or were less than one-fourth of the way to the next base shall be allowed to advance to the next base. Runners who were more than one-fourth of the way to the next base shall be awarded two bases.
9.04. Use of the infield fly rule is optional and can be called only by the batting team. It may be called on any ball hit in the air when there are runners on both first and second base with fewer than two outs. The call must be made prior to either a fielder touching the ball or the ball hitting the ground and it must be loud enough for all players on the field to hear. If the fielding team calls the infield fly or if the batting team calls it in a non-applicable situation, then distraction rules apply.
9.05. After reaching base, players must run for themselves. Pinch-runners are not allowed except in the following situations:
a. An official substitution to the batting lineup.
b. If a player who is on base is scheduled to bat, their spot on base is to be taken by either the last player to bat who is not currently on base or a player who is not currently in the lineup. If the player gets out in their at-bat, they have the option of returning to their spot on base.
9.06. If a base runner intentionally kicks or swats the ball, the play will be declared dead and all runners, even those who would otherwise be forced, shall return to the last base that they touched, unless that base is occupied.
9.07. A base runner may legally attempt to tag up as soon as a fielder touches the ball.
9.08. If a base runner is inadvertently touched by a hit ball while standing on base in fair territory prior to the ball being touched by a fielder, a single shall be awarded to the batter and only runners who were forced shall advance.
9.09. If a base runner is inadvertently touched with a hit ball while off base in fair territory prior to the ball being touched by a fielder, he/she shall be ruled out. The batter will be awarded a single and only runners who were forced shall advance.
9.10. A player running through first base must attempt to run one the right half of the base.
9.11. A player running through first base must remain in foul territory or else they can be tagged or plugged out.
10.00 - Suspended Games [top]
10.01. A new inning shall never begin more than 15 minutes after the day’s sunset time unless both teams agree.
10.02. In the event of rain, games will continue as scheduled so long as conditions are not too severe to play in. Teams should never assume that a game is rained out unless contacted by the commissioner.
10.03. If darkness, weather, or other factors make an in-progress game unplayable, the game will be suspended and continued from the exact point of suspension at a later date. An attempt will be made to ensure that suspended games are halted in between innings, rather than in the middle of an inning, to avoid providing an advantage to either team.
10.04. Teams will not be penalized for showing up with fewer players on the day that a suspended game is continued. Additional players may also be added to the bottom of the lineup when the game is continued, regardless of the inning. However, the batting lineup must be kept as similar as possible and all pitching regulations still apply to the series.
10.05. If the game is suspended prior to the commencement of the fourth inning, the game can be replayed in full with stats from the suspended game not counting if, and only if, both team captains and the commissioner agree. Such a decision must be reached by 11:59 P.M. on the date following the suspension.
11.00 –Schedule Formula/Playoffs [top]
11.01. In a normal nine team season, teams will be divided into three divisions of three. Every team will play four games against each of its two division opponents and two games against the other six teams for a total of twenty.
11.02. The three division winners, as well as one wildcard team, will qualify for the playoffs.
11.03. When two teams are tied in the standings at the end of the regular season and a playoff spot is on the line or matchups will be affected, the tiebreakers will be as follows:
a. Head-to-head record in the regular season
b. One-game playoff.
11.04. When a spot is not on the line and matchups are unaffected, the tiebreakers will be as follows:
a. Head-to-head record in the regular season
b. Division record (Only if both teams are in the same division)
c. Coin Toss
11.05. A one-game playoff counts as a playoff game, for both eligibility and statistical purposes.
11.06. If both teams are from the same division, then the home team in a one-game-playoff will be the team with the better division record. Otherwise, the home team will be determined by a coin toss.
11.07. Any playoff-eligible player may pitch in a one-game playoff with no bearing on his eligibility to pitch in any other game.
11.08. Playoff series will be three games long. The team with home-field-advantage will be home for games one and three.
11.09. In the first round of the playoffs, the team with the best record will play the playoff team with the worst record. If there is a tie for the worst record between a division winner and the wildcard team, they shall play the wildcard.
11.10. The wildcard shall not have home-field-advantage for any playoff series. In a playoff series between two division winners, the team with the better record shall have home-field advantage. If the teams have the same record, follow Section XI, rule 4.
11.11. In a playoff series, a player may pitch in multiple games if, and only if, one of the following conditions is met
a. The player pitches in games one and three but not in game two.
b. The player pitches exclusively as a closer, in which case the player is eligible for all three games.
12.00: Scheduling [top]
12.01. Scheduling will be very flexible during the regular season. However, playoff dates are set months before the start of the season and will not be changed unless the captains of all potentially affected teams and the commissioner agree on the change or highly extenuating circumstances, such as severe weather, force the playoffs to be pushed back.
12.02. For the first six weeks of the season, the schedule for a given week will be posted nine days in advance. Once the schedule is posted, it is final unless the team captains and the commissioner agree to a change. The schedule for the entire second half of the season will be released all at once around the midway point of the season.
12.03. During the first half of the regular season, all scheduling requests that are presented to the commissioner by 11:59 PM, two Thursdays prior to Sunday in question, will be honored if possible.
12.04. Requests for a specific time slot in a given week will be awarded on a first-come-first-served basis. Teams are encouraged to inform the commissioner of a request as soon as they are aware of a conflict, even if the date in question is months away. It becomes more and more difficult to honor specific requests as the season progresses. If a team’s first request cannot be honored, viable alternatives shall be presented to the team.
12.05. Teams that prefer to play at certain times may inform the commissioner, which will add some weight to scheduling decisions. However, requests made out of necessity will always take precedence.
12.06. Two bye weeks are built into the schedule for each team. However, more bye weeks will be awarded upon request as long as the team is willing to play more than two games on another Sunday in order to make up for the additional bye week(s).
12.07. All series will start exactly at the scheduled time as long as each team has at least four players present. Subsequent games in a series shall always start minutes after the conclusion of the previous game.
12.08. If one team does not have at least four players at the scheduled start time, the other team will be given choice of home/away for both games of the series.
12.09. If a team does not have at least four players present 15 minutes after the scheduled start time of a series, they shall forfeit game one of the series. If they still do not have four players 45 minutes after the scheduled start time for game one, they shall forfeit the entire series as well as any other scheduled games for that day. If neither team shows up, then both teams will be given a loss in the standings.
Note: if this is the forfeiting team’s first offense of the season, the game(s) can be rescheduled if and only if both the opposing team and the commissioner agree to reschedule the game. Such a decision must be made by 11:59 PM on the date following the initially scheduled game(s).
12.10. All players who show up to a forfeited game or series shall be credited with the appropriate number of games played in regard to playoff eligibility.
For any scenario not covered in this rulebook, the ruling shall follow Major League Baseball’s rulebook.
