baseball. Baseball is a bat-and-ball sport played between two teams of nine players each, who take turns batting and fielding. The game proceeds when a player on the fielding team, called the pitcher, throws a ball which a player on the batting team tries to hit with a bat. The objective of the offensive team is to hit the ball into the field of play, allowing its players to run the four bases arranged at the corners of a ninety-foot square, or diamond, to score runs. The team with the most runs at the conclusion of nine innings wins the game, which is presided over by one or more umpires.

History

The evolution of modern baseball is often traced to mid-19th century United States, with the New York Knickerbockers playing a key role in formalizing early rules under Alexander Cartwright. However, its origins are linked to older bat-and-ball games like rounders and cricket from England. The sport's professionalization accelerated after the American Civil War, leading to the formation of the first major league, the National League, in 1876. The rival American League was established in 1901, and the first World Series between their champions was held in 1903. Key figures in its growth include Babe Ruth, whose power hitting revolutionized the game in the 1920s, and Jackie Robinson, who broke the color line in 1947 with the Brooklyn Dodgers. The sport has since become a global game, with strong traditions in nations like Japan, the Caribbean, and South Korea.

Rules and gameplay

A standard game consists of nine innings, each divided into a top and bottom half where the teams alternate between offense and defense. The defensive team fields a pitcher, a catcher, four infielders, and three outfielders. The pitcher delivers the ball toward home plate, and the batter attempts to hit it into fair territory. A batter who receives four balls (pitches outside the strike zone) is awarded first base, while three strikes result in an out. Common ways to record outs include the fly out, ground out, and force out. A batter who hits the ball over the outfield fence in fair territory scores a home run. The fundamental strategic contest is between the pitcher, who may throw various pitches like the fastball or curveball, and the batter. Managers make strategic decisions regarding pinch hitters, relief pitchers, and defensive substitutions.

Equipment and field

The primary equipment includes a hard, stitched ball with a cork-and-rubber core, a rounded wooden or metal baseball bat, and a leather baseball glove worn by fielders. The batter and catcher wear protective gear such as batting helmets and catcher's masks. The field is composed of the infield and the outfield, with the infield dirt forming the diamond whose points are home plate, first base, second base, and third base. The distance from home plate to the outfield fence, or outfield wall, varies by ballpark, a characteristic known for creating unique stadium features like the Green Monster at Fenway Park. The pitcher throws from a raised mound at the center of the diamond, with a rubber slab called the pitcher's plate set 60 feet, 6 inches from home plate.

Major leagues and competitions

The premier professional organization is Major League Baseball, comprising 30 teams split between the American League and the National League. Its championship is determined by the World Series. Other significant professional leagues include Nippon Professional Baseball in Japan and the KBO League in South Korea. The sport's premier international tournament is the World Baseball Classic, sanctioned by the World Baseball Softball Confederation. Baseball was a demonstration sport at the Olympic Games before becoming a full medal sport from 1992 to 2008 and again from 2020 onward; the 2020 Summer Olympics gold medal was won by Japan. Historic competitions also include the Caribbean Series and the Little League World Series for youth players.

Popularity and cultural impact

Often referred to as "America's pastime," the sport holds a central place in American culture, celebrated in works like the film *Field of Dreams* and the musical *Damn Yankees*. Its history is intertwined with social issues, as seen in the integration led by Jackie Robinson and the labor disputes epitomized by the 1994–95 Major League Baseball strike. Iconic venues such as Yankee Stadium and Wrigley Field are cultural landmarks. The sport has produced revered records and figures, from Joe DiMaggio's 56-game hitting streak to the home run chase between Mark McGwire and Sammy Sosa. Baseball terminology and metaphors, like "out of left field" and "touch base," are common in English vernacular. Its global reach continues to expand through international players like Ichiro Suzuki and events like the World Baseball Classic.
