Fantasy baseball is a game where people manage a roster of Major League baseball players. The participants compete against one another using those players' real life statistics to score points. It is one of the most commonly played fantasy sports games, and is arguably[according to whom?] one of the most difficult and time-intensive due to the 162-game season of the MLB and the inconsistency of players.
An early form of fantasy baseball was coded for an IBM 1620 computer in 1961 by John Burgeson, IBM Akron, and distributed for several years by the IBM Corporation. It allowed two teams to play one another using random number generation and player statistics to determine a game's outcome, including a play by play description. In the fall of 1961 Rege Cordic, a KDKA (Pittsburgh) radio personality, produced a radio show based on the program. The game was coded for a computer with only 20K in computer memory and was entirely self-contained.
Early forms of fantasy baseball were sometimes called chickens. One of the best-known was Strat-o-Matic, which in 1963 began publishing a game containing customized baseball cards of Major League Baseball players with their stats from past seasons. Participants could then re-create previous seasons using the game rules and the statistics, or compose fantasy teams from the cards and play against each other. The EMSBL (East Meadow Strat-O-Matic Baseball League) based in East Meadow, N.Y., founded in 1972, is believed to be the oldest continuously playing fantasy baseball league in the world. The league's 2012 season marked the league's 41st consecutive year of play.
The landmark tabletop game Pursue the Pennant (now DYNASTY League Baseball) debuted in 1985 and took baseball board games to much more realistic levels of play[according to whom?]; it incorporated ball park effects, clutch hitting and pitching, and many other nuances of the game. Fantasy baseball was the theme of Robert Coover's 1968 darkly comic novel The Universal Baseball Association, Inc., J. Henry Waugh, Prop., which dealt with themes of creationism and playing god.
The first public open fantasy baseball game, Dugout Derby, was developed in 1989 by Lee Marc, Robert Barbiere and Brad Wendkos of Phoneworks who teamed with a West Coast Ad Agency (Wakeman & deForest) to launch the game in twelve of the largest local newspapers across the country. Papers that offered Dugout Derby included the LA Time, Chicago Sun Times, and NY Post. Archives of Dugout Derby are available in most public libraries. Dugout Derby allowed readers to create a team of major league players, earn stats for those players based on actual performance, trade those players on a daily basis, and accrue points in an effort to compete against one another to win prizes.
Copious materials accessible since 2006 in the Jack Kerouac Archive at the New York Public Library show that American writer Jack Kerouac (1922–1969) played his own form of fantasy baseball starting quite young and continued developing and playing this perhaps private version of fantasy baseball during most of his life. His version of fantasy baseball, however, was completely fictitious, with made up players and statistics. At the Library from November 2007 to February 2008, an exhibition on Kerouac's life and works includes several display cases of Kerouac's highly detailed fantasy baseball records, including charts, sketches, and notes.
Rotisserie League Baseball 
The "Rotisserie" scoring system in Fantasy Baseball became popular in the 1980s. The scoring system was popularized by group of journalists and formalized under the title Rotisserie League Baseball in 1980, 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 inventing the scoring system, coming up with the idea on a flight to Texas. After presenting his first vision of rotisserie baseball to friends there, none seemed interested. Upon returning to New York a month later he received an enthusiastic reception from a different group of friends, who then collaborated on the first league to use the system.
According to the rules, players (termed "owners") in the Rotisserie league would draft teams from the list of active Major League Baseball players and would follow their statistics "during the ongoing season" to compile their scores. In other words, rather than using statistics for seasons whose outcomes were already known, the owners would have to make similar predictions about players' playing time, health, and expected performance that real baseball managers must make.
Because Okrent was a member of the media, other journalists, especially sports writers, were introduced to the game. Many early players were introduced to the game by these sports journalists, especially during the 1981 Major League Baseball strike; with little else to write about, many baseball writers wrote columns about Rotisserie league.
Rotisserie league baseball, nicknamed roto, proved to be hugely popular, even in the 1980s when full statistics and accurate reporting were often hard to come by. The traditional statistics used in early Rotisserie leagues were often chosen because they were easy to compile from newspaper box scores and then from weekly information published in USA Today. Okrent, based on discussions with colleagues at USA Today, credits Rotisserie league baseball with much of the early success of USA Today, since the paper provided much more detailed box scores than most competitors and eventually even created a special paper, Baseball Weekly, which almost exclusively contained statistics and box scores. Local papers soon caught up with USA Today's expanded coverage.
The advent of powerful computers and the Internet revolutionized fantasy baseball, allowing scoring to be done entirely by computer, and allowing leagues to develop their own scoring systems, often based on less popular statistics. In this way, fantasy baseball has become a sort of real-time simulation of baseball, and allowed many fans to develop a more sophisticated understanding of how the real-world game works. According to statistics from a 2009 article in Forbes, nearly 11 million people play fantasy baseball today.
Fantasy baseball has continued to grow [based on recent studies from the Fantasy Sports Trade Association (FSTA.org)], but has been overtaken by fantasy football as the most popular form of fantasy sports. This is primarily because some of those sports, such as football and auto racing, only participate once a week, making it easier for a person to make adjustments, since they do not have to check their team daily.
The oldest continuously operating Rotisserie League in the world is the Roach Motel League, founded in 1981 at Columbia University in New York. Original Rotisserie League member Glen Waggoner was an administrator at Columbia and he passed along the rules to a group of undergraduates. The Roach Motel League, still consisting primarily of original members, has held a draft and played the game every year since 1981.
Player selection 
Rotisserie leagues and their descendants typically draft teams before the season begins (or very shortly thereafter). One approach is to hold an auction, whereby each owner has a fixed amount of money to bid for players, and he must fill his team's roster within their budget. Another approach is to perform a serpentine system draft of available players until all teams are filled.
In either case, the skills of the team managers come into play in the "preseason" by their knowledge of the talent and ability to forecast the performance of Major League Baseball players and prospects for the coming season. The team managers draw on a great variety of sources of information, including tout sheets by various forecasters, who predict the coming season's performance and the likely overall "value" (often in terms of auction dollars) of the Major League players.
Some leagues allow teams to keep some players from one year to the next, allowing savvy owners to build fantasy dynasties. These leagues are often referred to as "Keeper Leagues". Keeper leagues have the same people in them, and owners keep their players, unless any off-season moves are made.
Many leagues allow teams to trade with each other during the season, as well as to replace players who get hurt or stop performing well with players from the pool of those who are not presently owned. However, some leagues prohibit such in-season "free agent" replacements, feeling that the game is more interesting when teams must live and die by the quality of their draft.
Also, some leagues limit free-agent moves that a fantasy team can make per season, and a team may not just drop all of their players if they are not progressing well during a season. The free-agent limit is also sometimes used to limit the so-called "pitch-and-ditch" tactic, a method of play in which a manager picks up a free-agent pitcher with the intention of using him in only one game before replacing him with a pitcher who is scheduled to start the following day.
In most leagues, when a player who was injured returns to play, it is the choice of the team manager who to drop from his team. Usually, they are not forced to drop the replacement. Some companies actually offer real-world insurance on fantasy league players.
Many fantasy leagues are played for money. Owners pay an ante or entry fee at the beginning of the season and may also be charged for in-season activity such as trades and "free agent" acquisitions. The pool of money is collected and then distributed to the winner(s) at the end of the season. Most often, however, the main reward of fantasy games is bragging rights or pride in the participants' ability to assess baseball talent. Established leagues often have a plaque or trophy that is passed to the annual champion.
Game play 
There are different ways to play fantasy baseball. One way to play is a head-to-head format that makes each individual team play against a different team each week to acquire wins through total points scored for the week. Teams with the most wins at the end of the season often enter into a playoff similar to the MLB postseason. The winner is the team that doesn't lose in the playoffs, or has the most points at the end of season if the league does not hold playoffs.
Another style, the original style of playing fantasy, is rotisserie. The statistics compiled by the players from each team are then ranked by category, and the team with the highest cumulative rank at the end of the season is determined to be the winner.
The original Rotisserie League used the following statistics:
- team batting average (total hits divided by total at-bats)
- total home runs
- total runs batted in
- total stolen bases
- total wins
- total saves
- team earned run average (9 times total earned runs divided by total innings pitched, the lower the better)
- team WHIP (total number of hits and walks allowed by pitchers divided by total innings pitched, the lower the better)
This is often called a "4x4" league (4 hitting stats and 4 pitching stats). Many leagues adopt a "5x5" format, with runs scored and strikeouts added as hitting and pitching stats, respectively. Still other leagues are "6x6", most commonly adding OPS (OBP plus SLG), and holds. Occasionally, a league will adopt a format that keeps track of more statistics (such as a '7x7"), vary the stats tracked to favor hitting or pitching, or include fielding statistics such as fielding percentage. Other modifications to the rules include a minimum number of at-bats and innings pitched for categories that are averaged; teams that do not make the minimum were awarded last place in the respective categories.
Typical set-ups for head-to-head leagues are:
- Head-to-Head Rotisserie: Wins, losses and ties are based on the team's performance in individual categories.
- Head-to-Head One Win: Just like H2H Rotisserie, but the winner receives just one win, rather than one win for each category the team wins.
- Head-to-Head Points: Stats accumulate points for each team (a Home Run/Stolen Base/etc. is worth a certain number of points), and the team with the most points at the end of the week is awarded a win. These leagues often take advantage of several other statistical categories, from outfield assists to quality starts.
Opponents are dictated by a round-robin system. At the end of the season, the team with the best win-loss record is the victor.
Many head-to-head leagues also feature playoffs over the last 3–4 weeks of the MLB regular season. A set number of teams make the "postseason" and play a single-elimination tournament to decide a victor.
The art of the trade is highly strategic and fantasy owners can adopt many different strategies. There are also regional nuances that pop up in leagues around the country. For instance, in Connecticut, owners often "Jones" their trade offers. Named after its developer Troy Jones, "Jonesing" a trade is when you know you have an underperforming player who you want to drop, but include him in many trade offers to members in your league. You talk him up like his struggles are short term and he'll be an asset to your team down the road. However, shortly after no one accepts your offers, you drop the player to waivers (i.e. "Jones" him to waivers).
Fantasy trade referees 
The growing popularity of fantasy baseball has created a niche for fantasy baseball trade referees. Owners of fantasy teams often trade players, and often those trades incite disputes within leagues. Third party websites provide fantasy players a place to have their trades reviewed by a panel of "judges" in exchange for a fee. Decisions are rendered based on the specifications (number of teams, statistical categories, etc.) of the players' leagues. These third party sites are becoming a source of controversy due to their questionable value with all the free forums available to modern day fantasy players.
New formats 
New fantasy baseball formats have appeared that combine a traditional points-based competition with a liquid market that is used to facilitate real-time player trading. These games eliminate the need for fantasy trade judging by having team owners buy and sell players on a trading floor instead of negotiating trades directly with other owners. Another new format of fantasy sports is 'daily fantasy sports'. Rather than joining leagues and selecting rosters that compete for an entire season, competitors are able to draft a line-up for a single day and compete against others with cash being awarded to the winner just hours after the games on the field that day have ended. A typical contest would pit 2, 4 or 6 people against each other.
There are also fantasy baseball leagues that specialize in the Major League Baseball playoffs. Many fantasy baseball leagues stop their seasons at the end of the regular season.
Simulation games use computer programs, processing actual MLB player statistics, to generate results for contests matching teams composed of MLB players ‘drafted’ by ‘owners.’ This is thought to produce an experience which is more akin to that of being a real general manager. Notable simulation games include ones using historical stats such as Diamond Mind Baseball, DYNASTY League Baseball and Strat-O-Matic. Fantasy baseball simulation games that use a “predictive” model, meaning managers must guess how their players will perform, include Baseball Manager, Box Baseball, Franchise Ball and Scoresheet Baseball.
Keeper league 
Any fantasy baseball pool that "rolls over" into other years is called a "Keeper" or "Dynasty" league. The leagues can be run each year in any of the above formats with a winner declared at the end of each season. At the end of the year team managers decide which players they wish to protect (the number varies – from protecting and keeping all players, to keeping just one player). Before the MLB season opener, a fantasy draft is held to fill out the rest of the roster.
Many keeper leagues, as well as some single season leagues, have adopted salary cap rules similar to the NHL. In a "Salary Cap League", a salary is assigned to each player before the manager selects his team. Salaries are usually determined by the MLB player's real salary. Otherwise a number value is assigned – usually by an online baseball pool program – or it is determined through an auction process. Each manager must ensure that they do not go over the predefined salary cap when selecting players.
One emerging option for a keeper league is the Draft Round Values system. This is a Sabermetric approach for determining the values of players selected in a particular round. The round a player was selected in the previous season is conceded in the upcoming seasons draft when they are elected to be carried over. Tables are provided with these values and a conversion chart that calculates the rounds to be conceded when multiple players from the same round selected as keepers. These tables also work for balancing multiple player trades.
Keeper leagues are especially easy in auction formats, where last year's dollar values can be used to calculate keeper values. At least one league uses this system in combination with a minimum rookie keeper wage scale with great success.
Also some leagues have introduced a rookie draft into their fantasy league. By using the rankings from the last season to determine the draft order last place gets 1st pick and so on. Also in some leagues trading picks is also allowed.
