Rules for ATB
- Multiple divisions dependent upon
the total number of owners.
- Division winners plus three wild card
teams from each division make the playoffs (8 total).
- DH's will be used in the American
League, but not the National League.
- 28 Player Rosters (all active).
The 3 additional players are necessary because of injuries that occur
during the simulation.
- Positional makeup is entirely up to
the owner. You can carry as many pitchers or batters as you would
like, as long as you have 28 total.
- Players can be any year, for any
stadium 1871 through 2011.
- Team Name is entirely up to owner
- Any park from 1901 till know is
- Please submit the year and the park
you want (park factors change from year to year)
- DMB uses different PF's for each
combination of handedness and hit type (LH/RH for 1B, 2B, 3B, HR).
- In the off chance two owners select the same park, preference will be
given to the owner with the worst draft slot.
- We can't have two of the same parks
(two Fenway's, two Yankee stadium's, etc) even if owners request
Any batter with at least 450 PA
is eligible (Catchers need only have 370 Plate Appearances)
Pitchers with 50 IP or who have
appeared in at least 30% of their team games are eligible.
Only pitchers with at least 20
Games Started can be considered a full time starter in ATB.
Any pitcher is allowed to spot
start, even if they do not meet the 20 GS minimum.
For leagues without a DH,
pitchers may be assigned pinch hitting duty, but they can never be
inserted into the starting batting lineup unless he has enough at
bats to qualify as a batter.
Batter exceptions have been introduced as of
the ATB XIII season. These exceptions are designed to allow more
players who do not meet the above requirements to be used (1800s
players, strike shortened seasons, etc).
1) For teams with less
than 100 games in a season, a player from that team is only
eligible if he has appeared in 95% of his teams games. For teams
with more than 100 games, a player is only eligible if he has
appeared in 85% of his teams games.
2) However, batters must have
appeared in at least 65 games to be eligible. There are
some 1800s teams with 20 games in a season and that is not who
we are looking for.
- POSITION REQUIREMENTS. As an owner, I want to have the
ability to start a player out of position if I want to. If I want all
offense and no defense, I should be allowed to start by first basemen in
the outfield and be damned with the consequences. The problem of
course is knowing what the limits are. Since defensive ratings are
determined by me at the time the player is created, it leaves too much
leeway as go guessing. If a player happened to get garbage time in
1 game completely out of position should he be eligible for that position
in DMB? If so, how should I determine ratings after just one (or a
handful of games played)?
However, the DMB engine does
allow for this, and has a built in mechanism to downgrade defensive
ratings when players are out of position. It just needs a little
help and so the following rules are in place:
* Any player who appears in
at least 45% of his "real-life" games played a the position
will not suffer a penalty
* For players with more than
two rated positions, this percentage is dropped to 20%
* If, and only if, an owner
wants to break this rule, I will remove the DMB rating from this
second position and allow DMB to automatically downgrade as they
* If exemption is not
requested, all ratings remain as is and owners are free to keep
these players in back up positions.
2 Position Examples:
- Jim Hickman played 74 games
at 1B and 79 in CF - 48% and 52% respectively. He is eligible
at both positions.
- Dick Allen. played 91 at
3B, 47 in LF - 66% and 34% respectively. He is only eligible
to start full time
3 Position Examples
- Stan Musial. 41 LF, 64 CF,
76 RF - 23%, 35%, 42% respectively. Eligible to start full
time at all three.
- Randy Ready. 51 2B, 52 3B,
16 LF - 43%, 44%, 13% respectively. He is only eligible to
start full time at 2B
Players must be from a Major
Because the Negro League seasons
were roughly 1/2 as long as a Major League season, the sum of two
consecutive Negro League stat lines are used to determine the 'Real
Life" stats for each player. This combo season is entered into

Batters and 50 IP for pitchers

Clutch and Jam Ratings
All players elected to the Baseball
Hall of Fame will receive a bonus when performing in late and close
situations. From the DMB help file:
All DMB batters have Clutch
ratings and all DMB pitchers have Jam ratings. Both ratings are used
to raise the level of performance in the late innings of close
games. DMB gives out a limited number of good clutch and jam ratings
each season, and these players are more valuable in those
But the baseball research
community has yet to find any compelling evidence that certain
players are able to raise their game consistently in these
situations. The evidence seems to suggest that any apparent clutch
performance is an illusion, that the laws of chance predict that
some players are going to be up, some down, and some normal when you
choose any subset of 50-60 at bats out of his total for the season.
So the fact that a player raised his game in the 50-60 at bats that
fit the late-inning-close-game definition probably means he was just
Consequently, we give you the
option to use the clutch ratings or to turn them off. If you use
them, batters and pitchers with better-than-normal clutch and jam
ratings will be a little better than usual in the late innings of
close games. But this isn't a strong factor in the design of the
game, so we recommend that you avoid placing a lot of weight on
these ratings when making your decisions. It's rarely a good idea to
use a weaker player over a better one just because the weaker player
may have a better clutch or jam rating.
Durability is DMB's method of
determining how quickly a pitcher gets tired. The ratings are
Excellent, Very Good, Average, Fair, and Poor. I use the following
methods to determine what each pitchers durability rating is:
- Compare the pitchers complete game
percentage to the average complete game percentage of the league and
year he played
- If his CG% is 25% better than
average he gets an Ex rating; 11-24% better a Vg rating; -10 to +10 % an
Av rating; -11 - -24% a Fr rating; -25% or worse a Pr rating.
- However, special rules are in place
to ensure pitchers with an extreme amount of complete games are treated
favorably in the league regardless of the league averages.
- If a player has completed 90% of his games in real life he will
automatically receive an Ex rating.
- If a players has completed 80-89.9% of his games in real life, he will
receive at least a Vg rating. If the above method determines an Ex
rating, then that will be used.
- Ratings are subject to my
discretion. Generally, if a player appeared in twice the # of
innings as games played, he receives an Ex rating. If he has
appeared in roughly the same number of innings and games played, he
receives an average rating.
also take into account era and other written evidence when determining
- Draft Order determined randomly by
commissioner using the Excel "Random Number Generator" function.
- 28 Round Draft
- Each owner is pre-assigned a
specific 10 minute block of time to make a selection. If you miss
your block of time, you are skipped, and the next owner is allowed to
make a selection once his block of time has started. The
skipped owner can go back and make the missed selection at any time
- In general, the draft runs from 9
AM to 10 PM each weekday. For
those who can't make early picks you can email me your pick the night before.
- Owners can also submit lists to me,
in order of preference, and I will post a pick for them if they wish.
This is not recommended, but can be accommodated.
