. Players with better statistics in the previous season were more likely to receive favorable outcomes; this allowed ''National Pastime'' to become one of the first games to attempt to accurately simulate the performances of real-life MLB players.
A notable example of such games was
APBA, which was first released in 1951 and also contained cards of MLB players with in-game outcomes correlated to their stats from past seasons. Participants could compose fantasy teams from the cards and play against each other or attempt to re-create previous seasons using the statistics on the cards. Individual player cards and dice roll simulations were also emulated in the
Strat-O-Matic game, which was first released in 1961.
Daniel Okrent, who would later be credited with developing modern fantasy baseball, was an avid Strat-O-Matic player, telling ''

Rotisserie League Baseball
Modern fantasy baseball was developed and popularized in the 1980s by a group of journalists who created Rotisserie League Baseball in 1980. The league was named after the New York City restaurant La Rotisserie Française, where its founders met for lunch and first played the game.
Magazine writer-editor
Daniel Okrent is credited with introducing the rotisserie league concept to the group and inventing the scoring system.
Players in the Rotisserie League drafted teams of active MLB players and tracked their statistics during the season to compile their scores.
Like the Baseball Seminar league, rather than using statistics for seasons whose outcomes were already known to simulate in-game outcomes, team owners would have to make predictions about the statistics that MLB players would accumulate during the upcoming season. The success or failure of a particular fantasy team would therefore depend on the real-life performance of its players rather than the results of a simulation.
Rotisserie baseball, nicknamed ''roto'',
proved to be popular despite the difficulties of compiling statistics by hand, which was an early drawback to participation. The traditional statistics used in early rotisserie leagues were often chosen because they were easy to compile from newspaper
box scores or weekly information published in ''

''. Okrent credits the idea's rapid spread to the fact that the initial league was created by sports journalists, telling ''
Vanity Fair'' in 2008 that "most of us in the league were in the media, and we got a lot of press coverage that first season. The second season, there were rotisserie leagues in every Major League
press box."
According to Okrent, rotisserie baseball afforded sportswriters the opportunity to write about baseball-related material during the
1981 Major League Baseball strike, saying "the writers who were covering baseball had nothing to write about, so they began writing about the teams they had assembled in their own leagues. And that was what popularized it and spread it around very, very widely."
Continued expansion
In 1985, the Grandstand Sports Services launched the first nationally available rotisserie baseball leagues online through Q-Link (later

daily fantasy sports by rewarding each week's highest-scoring participants with vacation packages.
The growth of the Internet during the 1990s brought a "broad demographic shift in fantasy sports participation" because it enabled fantasy sports participants to instantaneously download tabulated statistics, rather than having to search for box scores of individual games in newspapers and keep track of cumulative statistics on paper. In 1995,

League types
A fantasy baseball league may be organized in a variety of ways. The original rotisserie leagues, as well as their modern counterparts, rank each team in a number of statistical categories at the end of the season. Points are then awarded based on these rankings.
For example, in an eight-team league, the team that collectively hits the most home runs might earn eight points, the team that hits the second most might earn seven, and so on. The number of statistics for which the teams are ranked may vary ''(see
Competition variations)''. Another common format is head-to-head competition, in which each team only competes against one other team in a given week. At the end of the week, the winner of each matchup may be determined in a variety of ways ''(see
Head-to-head variations)''. In addition to scoring variations, league organization may also differ based on the structure of each team's roster ''(see
Roster variations)''.
Competition variations
The original Rotisserie League Baseball used the following statistics:
* team
batting average (total
hits divided by total
at-bats)
* total
home run
In baseball, a home run (abbreviated HR) is scored when the Baseball (ball), ball is hit in such a way that the batting (baseball), batter is able to circle the bases and reach home plate safe (baseball), safely in one play without any error ( ...
s
* total
runs batted in
A run batted in or runs batted in (RBI) is a statistic in baseball and softball that credits a batter for making a play that allows a run to be scored (except in certain situations such as when an error is made on the play). For example, if th ...
* total
stolen bases
* total
wins
* total
saves
* team
earned run average (ERA) (9 times total
earned runs allowed by pitchers divided by total
innings pitched)
* team
walks plus hits per inning pitched (WHIP) (total number of hits and
walks allowed by pitchers divided by total innings pitched)
These statistics have become the standard for modern rotisserie leagues.
A league using these statistics is known as a "4×4" league because it uses four hitting stats and four pitching stats. Some leagues use a "5×5" format, with
runs scored and
strikeouts added as hitting and pitching stats, respectively.
Others are "6×6", which can involve adding new statistics or replacing ones in the original 4x4 or 5x5 format. For example,

fantasy writer
Tristan H. Cockcroft has proposed a 6x6 league in which batting average is replaced with
on-base percentage (OBP) and
slugging percentage (SLG), while innings pitched is added as the sixth pitching stat, among other changes. The rotisserie format can theoretically be expanded to encompass any number of statistics, though online support for such expansive leagues is limited (for example,

only offers 4x4 and 5x5 leagues).
Head-to-head variations
There are three major configurations for head-to-head play:
* Head-to-Head Rotisserie: Also called head-to-head each category, this format assigns wins, losses, and ties based on each team's performance in individual categories. For example, in a 5x5 league, if Team A performs better in six categories, Team A receives six wins and four losses for that week's matchup, while Team B receives four wins and six losses.
* Head-to-Head One Win: Also called head-to-head most categories, this format assigns wins, losses, and ties based on which team performs better in the most categories. For example, in a 5x5 league, if Team A performs better in six categories, Team A receives the sole win for that week's matchup, while Team B receives the loss. If each team performs better in the same number of categories, then each receives a tie.
* Head-to-Head Points: In this format, each category is assigned a certain number of points, and the team that performs better in each category receives the points. The team with the most points receives the sole win for the matchup.
In all three configurations, opponents are dictated by a
round-robin system. At the end of the season, the team with the best win–loss record may win the league, or

The number of teams that make the playoffs and the existence of a consolation bracket for teams that miss out may vary based on the website used and the customized settings employed by a particular league. For example, Yahoo allows leagues to have four, six, or eight teams make the playoffs.
Roster variations
* Keeper leagues allow teams to keep a set number of players on their roster from one year to the next and sometimes even assign them contracts for a certain number of years. In the first season of a keeper league, the draft is performed in the same way as any other standard league draft, however, in all subsequent years, the draft only involves players not selected to be kept on their team. Keeper leagues may allow each team to retain as few as one player or as many as every player on the roster except one.
* In dynasty leagues, each team keeps all players on its roster from one year to the next. Rosters are replenished with drafts of rookies and players who were not on a team the previous year.
* Salary cap leagues assign each eligible MLB player a salary before each season. The combined salary of each roster may not exceed a predetermined
salary cap

s, players who are not currently on any team, to their roster if the roster is not already full. There are a few possibilities by which teams may acquire these players:
* Under the waiver wire format, which is also commonly used in
fantasy football, teams may place claims on free agents until a predetermined deadline, at which time the team with the lowest position in the standings with a claim on a player gains that player.
Teams with lower positions in the standings are therefore said to have higher waiver priority. After acquiring a player, a team is moved to the bottom of the priority list.
* Under the Free Agent Acquisition Budget (FAAB) format, each team has a predetermined budget that may be used to bid on available free agents. If a team uses its entire budget, it will be unable to acquire new free agents until the league budgets are reset, which may occur on a weekly or even daily basis.
* The First Come, First Served (FCFS) format allows any team to add any free agent at any time with no restrictions.
Draft
Before each season, fantasy baseball leagues hold a
draft

Watercraft dimensions

in which each team drafts MLB players. These players are kept on the roster of the team that drafted them unless they are traded for other players or are dropped, whereby they enter a pool of unowned players that any team may claim. The order of draft picks may be determined randomly or by the league standings from the previous year, in which the team with the worst record picks first, followed by the team with the second-worst record, etc. In some cases, owners retain the same draft position in each round.
In contrast, in a traditional "
serpentine" or "snake" draft, owners draft players in a "snake" method, in which the owner who picks first in the odd rounds picks last in the even rounds, the owner who picks second in the odd rounds picks second to last in the even rounds, etc. in the interest of fairness.
In an

An auction is usually a process of Trade, buying and selling Good (economics), goods or Service (economics), services by offering them up for Bidding, bids, taking bids, and then selling the item to the highest bidder or buying the item from th ...
draft, each owner has an imaginary budget which must be used to purchase players in an auction format. Owners take turns nominating players for open bid, and the owner who bids the highest on each player receives that player, reducing his or her remaining budget accordingly.
One proposed advantage of auction drafts is their ability to offer every owner equal access to every player, whereas in a traditional format, a certain owner's desired player may be selected by another team before the owner's next turn to pick.
Drafts can be conducted in "live" or "auto" formats. Live drafts involve team owners selecting players in real time, while auto drafts are those in which selections are made automatically by computer based on pre-draft rankings set by each owner. Often, owners who are not present at the chosen time of the draft will "auto-draft" while the rest of the league makes their selections live.
Whether live or auto, the vast majority of fantasy drafts take place online, but some leagues hold in-person drafts in which selections are made on computers or physical draft boards.
Regardless of the format in which a draft is held, each team owner may employ a variety of strategies when making his or her selections. In order to select the best possible players, owners must evaluate the talent and forecast the performance of each player for the upcoming season. A variety of resources may be used to this effect, from rankings released by fantasy baseball journalists and websites to

s created by professional daily fantasy competitors.
Team rosters
A fantasy baseball roster is conventionally composed of players from each
position. Each team is allowed a set number of players on its roster, as well as a specified number of starters at each position that can be used in a head-to-head matchup. Owners may determine which players will start and which will be "benched" on a weekly or even daily basis. Only players who are designated as starters will have their statistics count towards the team owner's totals in the weekly matchup.
Just like in real baseball, players who are usually benched can become starters for various reasons: due to a starting player's injury, poor performance, or if the starter's team is not playing on a particular day. Whether to sit or start a player is also based on strategic considerations, such as the player's past and expected performance and the team he is playing, specifically its

. If a league does not have head-to-head matchups, then there may be no distinction between starters and bench players, as a team's end-of-season results are derived from the cumulative statistics of the entire roster.
The precise positions included in online rosters vary widely, along with the number of players allowed at each position and on each team's bench. For example, ESPN's default roster includes one middle infielder, one corner infielder, and one utility player. A default Yahoo roster includes two utility players, neither of which is designated as a middle or a corner infielder. DraftKings, which operates a variety of daily and weekly games, does not have utility slots on its rosters for some games, but does for others.
The following table lists the default roster settings for head-to-head leagues managed by ESPN, Yahoo, and CBS Sports,
as well as in DraftKings' MLB Classic weekly competitions. A note next to a position's name indicates its definition.
The injured reserve is used to store players with real-life injuries who are unable to compete for an extended period of time. Fantasy leagues usually only allow players to be placed on injured reserve if they have been placed on the
injured list by their MLB team.
Some leagues limit teams to a certain number of free agent transactions or trades per season or per week. Such limitations are commonly used to prevent team owners from artificially inflating their statistics or otherwise achieving an unfair advantage by using an excessive number of players during a matchup. Another common limitation on roster moves is the adoption of a list of "undroppable" players, generally those selected in the first few rounds of the draft or those who are generally deemed too valuable to be allowed to freely change teams without being exchanged for other players.
Demographics
According to the
Fantasy Sports & Gaming Association (FSGA), an estimated 62.5 million people played fantasy sports in the US and Canada in 2022.
The FSGA estimated that 19% of American adults played fantasy sports in 2023, compared to 13% in 2014.
Around 22% of fantasy players play fantasy baseball, making it the third most popular fantasy sport behind
fantasy football and
fantasy basketball.
A 2023 FSGA survey found that 64% of fantasy sports players were male, 48% were between the ages of 18 and 34, and 84% had a college degree or higher.
A 2015 analysis found that 89.8% were white and 51.5% were unmarried.
