Retro Sim Baseball League Constitution

1.00 League Format


The Retro Sim Baseball League (RSBL) will consist of two leagues, the American and National Leagues. Each league will consist of 6 teams.


Franchise names will be at the discretion of owners. Once selected, they may not be changed in order to keep an accurate and simplified league historical database.


The season will be 140 games until 1904, when it will be 154 games. When playing the 140 game schedule, teams will play 16 games against the other teams in their league, and 10 against the opponents in the other league.


Season play will be pure; the American League teams will only play other American League teams, the National League teams will play only other National League teams.


Joining and playing in the league is free; there are no dues or other charges.

2.00 General Playing Rules


RSBL is a 100% APBA Baseball for Windows (BBWin) 5.75 computer league, using League Manager (LM) and AIM.


The use of the Designated Hitter will mirror MLB rules. Specifically, the DH will NOT be used in either league until the 1973 season. At that time, it is optional in the American League.


All regular season games in RSBL will be simmed in blocks (normally 20 games). The post-season games are played traditionally (live, either solo or head-to-head via TeamViewer).


Owners are responsible for declaring their team's MicroManager and providing a copy to League Management to be posted on the league website so all can access. In the event that a team fails to designate a MicroManager, Buck Miller IV will be used.


Ballpark effects will not be used.


The team with the worst overall record in RSBL the previous season will be responsible for simming the blocks of games the following season.

3.00 Team Rosters


Major League roster sizes will be based on the number of available players each year. Roster size will never be less than 30, or more than 40 players during the season. It is each team's responsibility to keep enough carded players on the MLB roster to provide full seasonal coverage at all offensive positions as well as pitching.


A 30-man roster is used for each block.


Active rosters may be expanded to up to the 40-man limit after game #132 of the season has been played.


Players who did not play in the current season (previously carded players) may be retained. These players will be designated with "DNP". They may not be used in games under any circumstances. DNP players count against the designated roster limit.


During the season teams are not allowed to go over 40 players. In the off-season teams may exceed the 40 man limit but will be forced to cut down to 40 by September 1st.


If a player misses a full season due to military service, they may be placed on a special "Military Reserve" list (MR). Players on MR do not count against the normal roster limit. When the player regains their card, they must be taken off the MR list or released. A cap of 3 MR Roster Spots per season has been set. Teams wishing to retain more than 3 Military Service players would have to use Active Roster spots to retain the additional players and would be subject to the cut requirements as listed under Player Drafts.

4.00 Batting Limitations


AIM will be used to manage all batting limits.

5.00 Stealing Limitations


Players are limited to 150% of their actual steal attempts.  Due to the nature of the league (simmed games), it will be up to teams to self-police their steals.  Players who have reached the 150% threshold will have their steal rating reset to N-0 for the remainder of the regular season.  (These players will be reset to their original rating for postseason play, if applicable.)

6.00 Player Substitution


A player may play at a non-rated position only when the starting and all rated backup players for that position have been injured, ejected, or substituted. Pinch-hitting or pinch running for the last available rated player at a position is allowed only from the 9th inning on.

7.00 Pitching Limitations


AIM will be used to manage all pitching limits.


Pitchers without a starting grade cannot start unless absolutely required due to injury. Any pitcher may be used in relief.

8.00 Injuries


We will use the "Fatigue Only" AIM injury setting, so injuries will never extend beyond the current game.

9.00 Rainouts


All games will be played/simmed in Domed stadiums to prevent rainouts.


Any results submitted with rainouts will be ignored and the series will be simmed.

10.00 Instructions and Results


Each manager must provide an f-file at the beginning of the season, designating team pitching rotation, roster, and lineups. This file may be changed after each block.


The 30-man active roster for each series must include a minimum of 2 rated players for each defensive position and a minimum of 5 rated players for the outfield. Each roster and lineup must have a minimum of 4 pitchers (may be rated relievers or starters with available relief appearances and innings) available for relief, and 4 starting pitchers, 3 of which are ineligible to pitch (resting).


Managers must email their f-file changes to the email account in a timely fashion upon the conclusion of each block.


Pitching rotations are to be scheduled for a minimum of the upcoming block.  Managers are responsible to manage their rotation so that starters will be available (Rested or Ready status) for their scheduled starts.


Any manager who becomes AWOL after thirty (30) days, without having made prior arrangements with the commissioner, may be immediately terminated at the discretion of the commissioner.

11.00 Post-Season Play


The 2 league champions will advance World Series, and will play a best of 7 series. The format of the World Series will be 2-2-1-1-1.


League ties will be broken by a one-game playoff, at the home of the team with the better record in head-to-head play. In the event of a head-to-head tie, the next tie-breaker used will be divisional record. If still tied, a coin flip by the commissioner will determine the home field.


The World Series home team will be the team with the best regular season record. In the event of a tie, the following criteria will be used to break the tie: 1) Best road record 2) Most runs scored 3) Fewest sims 4) Coin flip.


Player fatigue from the regular season will carry over into the playoffs.


Playoff rosters will be 30 players and must be declared before the start of the playoffs.


Playoff rosters cannot be changed once the playoff start.


Only starting pitchers with 50 or more innings pitched, and relievers with 25 or more innings pitched are eligible for post-season play.  A starter or split-grade pitcher with at least 25 but less than 50 innings may be used in the post-season, but only in relief.


Innocuous batters (OPS < .600) and pitchers (Grade 1-3, MBF 1000) are eligible for the post-season regardless of their actual MLB at-bat and innings totals.


A DH will be used at all games hosted by the American League team (startiing in 1973); no DH is used in the National League ballpark.

12.00 Awards


MVP, "CY Young", "Rookie of the Year", and "Fireman of the Year" votes, for each league, will be taken at the end of the season and acknowledged.


A voluntary Awards Committee will be formed at the end of the season to vote on league All-Stars, Gold Gloves, and Silver Sluggers. Any owner that wishes to participate may join the Awards Committee.

13.00 Player Drafts


An annual draft of available players (unowned carded players) will be conducted each year on a date determined by the commissioner. The draft will be held via the league draft website and will be at least 10 rounds in duration.


All unaffiliated players on the new APBA data disk are eligible for the draft.


The draft order will be set in the inverse order of the final standings. In the event of ties for any position, the previous year's standings will be used.


A weighted draft lottery will be used to determine the order of the first X picks in the first round. All teams (X) with a record under .500 will participate in the lottery. The team with the worst overall record will have X chances for the 1st overall pick; 2nd worst gets X -1, 3rd worst gets X -2, and so on). No team can lose more than 2 slots in the lottery draft order; once a team has lost 2 slots they will be automatically inserted into the next open slot before the lottery continues. The lottery is only for the first round; all other rounds will be based on inverse order.


In the event that more than three teams tie for the three worst records, the lottery will be expanded to include the additional teams.


Draft picks may be traded at any time that trading is open, including during the actual draft.


Prior to the draft, the commissioner will announce the roster size for the upcoming season. In order to participate in the upcoming draft, teams will need to cut down below the roster size in order to draft players. For example, if the roster size is 30 players, a team will need to cut down to at least 29 players to participate.


In order to have a 1st roudn pick in the draft, a team must cut down to 5 less than the roster size. For example, if the roster size is 30, a team must cut down to 25 in order to retain their 1st-5th round draft picks.


If a team cuts to 1 below the roster size (29/30), they will have a 5th round pick only in the draft. Cutting to 2 below gives 4th and 5th round draft picks; cutting to 3 below provides the 3rd/4th/5th round picks, and cutting to 4 below gives the team their 2nd-5th round picks.


Teams may cut as many players each year as they like, and will be granted enough draft picks to fill their roster. No team will be permitted to draft beyond the established roster size, so pre-draft planning for each team is very important.


Instructions, draft order, and a list of eligible players will be distributed prior to the draft.

14.00 Trades


Trades can take place at any time during the season, with the exception of short roster freeze periods that will be announced by league management.


No trades are official until reported by both managers to the League Management for confirmation. Trades will be reported to the league in a timely manner via the website and mailing list.


The in-season trade deadline is at the series that contains Game #133. No trades may take place between Game #133 and the end of the playoffs. The commissioner will announce when trading is reopened at the conclusion of the World Series.


Draft picks for the next upcoming (or current, if in progress) annual draft are the only draft picks permitted in trades.


In the event that collusion or other unfair/unethical is suspected, League Management will form a Trade Committee of 5 owners (picked at random) to review the trade in question. If a majority of the Trade Committee feels that there is a breach of ethics and fair play the trade will be overturned. The Trade Committee will be instructed to only consider foul play and an obvious attempt to cheat; the trade being subjectively uneven is not grounds in and of itself to nullify the trade.

15.00 AIM Adjustments


Prior to the season, the commissioner (or his delegate) will perform adjustments to various AIM player ratings.


Innocuous batters (OPS < .600) with an injury rating of J-3 or J-4 will have it adjusted to J-2.


Any batters with a Season Factor (SF) less than 100 will have it normalized to 100. This will reduce the player's PR as a result (e.g. a 1000/60 player will become a 600/100 player). With SF=100, the player will no longer be "games-limited" in their usage.


Pitchers with a grade of 1, 2, 3, or 4 will have their Maximum Batters Faced (MBF) set to 1000. Split grade pitchers with both grades 4 or less will also be adjusted to 1000 MBF.


Grade 1-4 starting pitchers will have their injury rating set to J-2 and their Durability rating set to 2. This will result in their MRR being calculated to 35 and RF to 9.


Grade 1-4 relievers will have their injury rating set to J-0 and their Durability rating set to 1. This will result in their MRR being calculated to 18 and RF to 7.


Split grade pitchers with both grades 4 or under will have their injury rating set to J-1 and their Durability rating set to 2 as a starter and 1 as a reliever.


If a split grade pitcher has either grade greater than 4, they will not receive any AIM adjustments.

16.00 Rule Changes


All rule changes to the RSBL Constitution must be approved by a two-thirds majority of the voting managers.


New additions to the constitution must receive majority approval.


Any league manager may submit rule proposals.


Voting on rule proposals/charter modifications for the following season will take place within 30 days after the playoffs are completed. No in-season modifications to the charter will be permitted.
