Baseball

Baseball is a game or sport using a small, hard, spherical ball and a wooden bat, played between two teams of nine players each on a large field that has, in part, a square circuit, called a diamond, consisting of four bases.

For many years, American tradition held that the game was invented by Abner Doubleday in 1839 in Cooperstown, New York, the site, since 1939, of the National Baseball Hall of Fame. However, the modern game actually developed out of the 18th-century English game of rounders, which thus is the immediate predecessor of baseball in its present form. This development occurred in 1845 when Alexander Cartwright formulated the rules that to this day serve as the basis of the modern game.

In time, the game of baseball came to be considered the American national pastime. Over the years, the game has been so much a part of the American cultural fabric that many of the major social issues of the day have found their expression in the game including labor strife, racial segregation (and integration), the role of sport in society, the development of sport as big business, and certain social ills such as professional gambling and doping.

The United States has not been alone in claiming baseball as its National Pastime as the sport has had over a century-long history in Cuba, Japan, the Dominican Republic, Venezuela, Nicaragua, Mexico, Canada, Korea and Taiwan. The game has received international recognition, first as an Olympic sport, and more recently through the World Baseball Classic (WBC) and various regional tournaments.

Rules
Baseball is played at several levels and the rules of the game, though they are alike in broad outline, vary in their details depending upon whether we are referring to Major League Baseball (MLB), collegiate baseball, high school baseball, or little league. Each version is governed by its own particular jurisdictional authority which has control over the adoption and implementation of the rules for that level of play. The following outline refers to the common features of all games of baseball.

Field of play
The baseball field is divided into two basic areas: the infield and the outfield. The infield contains four bases which are arranged in a square. In one corner of this square is located home plate. The other three bases are located at the other corners of the infield square and are called (in counterclockwise order) the first, second, and third base.

The entire field of play is defined by: a) two lines (called the foul lines) extending from home plate down to and beyond the first and third bases; and b) the outfield fence, which is a roughly circular arc connecting the two foul lines at some distance (in major league baseball, typically varying between 250 and 400 feet) from the home plate.

The area contained within the right angle defined by the first and third base lines and extended out to the outfield fence is called fair territory. The region outside these lines to the right and left is foul territory. The region beyond the outfield fence but within the extension of the foul lines is home run territory.

Within fair territory the infield is separated from the outfield by a quarter circle just outside of but including the square with the bases. The region of fair territory beyond this circular arc is called the outfield.

Play of the game
A baseball game is divided into separate segments called innings (defined below), with 9 innings constituting a complete, regulation-length game. In the course of the game, the opposing teams attempt to score runs (as described below) with the team having the most runs at the conclusion of the game being the winner.

At the start of the game, the host, or home, team sends 9 of their players onto the field of play. Except for the pitcher and catcher (see below), these players are positioned and move about, in dependence on the actual game situation, in such a way as to prevent, to the best of their ability, the other team from scoring runs.

Meanwhile, the opposing team (the visiting team) is at bat and they send their 9 players, one at a time, in an order designated by their team manager prior to the start of the game, up to the home plate area where they attempt to successfully reach base (as described below) and then, usually with the help of their teammates who follow in the batting order, traverse the bases in order until they arrive safely back at home plate, thus scoring a run. For its part, the team in the field (the defensive team) attempts to record 3 outs after which the side at bat is said to be retired and the two teams then switch positions with the team which was just at bat going out into the field of play to take up defensive fielding positions and the team which was just in the field coming off the field to take its turn at bat.

When the team now on the defensive is able to record 3 outs in their turn, one alternation is then completed wih both teams having had a turn at bat. This completes the first inning. Nine such innings, or alternations, constitute a complete, regulation-length game. The team with the most runs scored at the end of these 9 innings is the winner. If both teams have scored the same number of runs, additional innings are then played until one team or the other is able to obtain a lead by having scored more runs then their opponents.

The opposing pitcher (positioned on the pitcher's mound) throws the ball towards the batter (positioned on the home plate) who tries to hit the ball. He makes a mistake
 * if he fails to hit a correctly thrown ball (a strike), or
 * if he attempts but fails to hit an incorrectly thrown ball (a strike), or
 * if he bats the ball into foul territory (a foul ball) which also counts as strike, unless it would be the third strike.

He is eliminated
 * after three mistakes (a strikeout), or
 * if his ball is caught by a member of the defensive team (an out).

A pitch is incorrect (a ball) if the ball does not pass the prescribed area above the home plate (the strike zone). After the fourth ball the batter advances freely to first base (a walk).

When the ball is put into play, the batter tries to advance to 1st base. If the batter gets to first base before the opposing team can throw the ball there and secure it, then he is safe. If the opposing team throws and secures the ball before the batter arrives at first base, then the batter is called out. The idea for the offensive (batting) team is to continue around the basepath in a counterclockwise motion and get to each base (1st, 2nd & 3rd) without getting thrown out or tagged out. The final touch is to make it back to home plate without getting thrown out or tagged out. Once a batter crosses home plate, the offensive team is awarded a run. The team with the most runs at the end of the game wins. It is the only popular sport where the defense is in possession of the ball.

Origins
Baseball can trace its origins back to the English stick and ball games of cricket and rounders, arriving in America with the early colonists. Baseball mythology attributes the creation of the game to Abner Doubleday in 1839, who is said to have come up with the rules and the name "baseball" during a game of "town ball" in Cooperstown, New York. The "creation myth" associated with Doubleday is credited to Albert Spalding and the Mills Commission whose controversial ruling in 1905 solidified the myth that baseball was created by the Civil War General in his youth in Cooperstown, New York. Subsequent research has proven that Doubleday was not in Cooperstown, NY in 1839, nor had he ever mentioned baseball in any of his subsequent memoirs. Spalding and Harry Wright had a friendly bet over the origins of the sport. Wright claimed the origins of baseball to be in the British game rounders, while Spalding and his strong sense of nationalism claimed that the sport and its attributes matched the character of Americans. Spalding's Mills Commission attributed the founding of the sport to Doubleday through the supposed testimony of Abner Graves, who claimed to have seen Doubleday write the rules of the sport in a schoolyard in Cooperstown, New York sometime in the late 1830's or early 1840's. It was Spalding who pinpointed the exact date of the genesis of baseball to 1839. However, it can be more accurately attributed to Alexander Cartwright. In 1845, at the urging of Cartwright, a group of young gentlemen from Manhattan formerly organized themselves as the New York Knickerbocker Base Ball Club. At the time, baseball had no standard set of rules and could be played differently from game to game. The Knickerbockers developed the first formal set of rules for the game, including establishing foul lines, the strikeout, and runners now were to be tagged or thrown out instead of being thrown at. The Knickerbockers played their first game on July 19, 1846 at the Elysian Fields in Hoboken, New Jersey, against the New York Base Ball Club, losing by a score of 23 to 1. New York City was growing rapidly and new clubs continued to be created, leading to more formal games. In 1857, the 16 organized clubs formed he National Association of Base Ball Players, which played under Knickerbocker rules. The 1850's also saw the adoption of more modern rules; nine players on each team, the bases moved to 90 feet apart, the ball was modified from the current lightweight ball to a harder, horsehide covered rubber ball designed to be hit and thrown harder and faster, and declaring the team with the most runs at the end of nine innings the winner.

The popularity of baseball spread rapidly, reaching most of American in the 1860's. Up until 1869, baseball was played as an amateur game. That changed with the Cincinnati Red Stockings, the first professional team, which was financed by Harry Wright.

Statistics
Baseball is a sport driven by statistics, with records kept for every facet of a players career from batting average to innings pitched. The all-time leaders in areas such as home runs and strikeouts are revered by fans of all teams.

Statistics are deemed to be so important to the game of baseball that in the 1970s statisticians developed various methods of using them in attempting to objectively analyze baseball performances. Pioneered by Bill James, the study of sabermetrics has become a popular tool used by general managers in Major League Baseball to fill out their rosters with players that bring the greatest value to the team.

Many years ago, one of baseball's most revered innovators and gurus, Branch Richey, famously declared, "There is nothing on earth anybody can do with fielding." Since then, however, many statisticians, including Bill James, the most famous of them all, have tried to spin gold from the limited dross of fielding statistics available, with limited success. On July 10, 2009, however, a new computerized recording system was announced by Sportvision and Major League Baseball: "A new camera and software system in its final testing phases [that] will record the exact speed and location of the ball and every player on the field, allowing the most digitized of sports to be overrun anew by hundreds of innovative statistics that will rate players more accurately, almost certainly affect their compensation and perhaps alter how the game itself is played."

The article goes on to say, perhaps with hyperbole: "Teams have begun scrambling to develop uses for the new data, which will be unveiled Saturday to a group of baseball executives, statisticians and academics, knowing it will probably become the largest single advance in baseball science since the development of the box score."

The system has already been installed at the home park of the San Francisco Giants and, at the cost of several million dollars, will be working in all 30 Major League stadiums by the end of 2010. How useful the glut of new statistics derived from the system will be to fans and team executives remains to be seen.
