In baseball statistics, a hit, also called a base hit, is credited to a batter when the batter safely reaches or passes first base after hitting the ball into fair territory with neither the benefit of an error nor a fielder's choice.
In baseball, a home run, homerun or homer is scored when the ball is hit in such a way that the batter is able to circle the bases and reach home plate safely in one play without any errors being committed by the defensive team. A home run is usually achieved by hitting the ball over the outfield fence between the foul poles without the ball touching the field.
In baseball, the strike zone is the area of space through which a pitch must pass in order to be called a strike even if the batter does not swing. The strike zone is defined as the volume of space above home plate and between the batter's knees and the midpoint of their torso. Whether a pitch passes through the zone is decided by an umpire, who is generally positioned behind the catcher.
Rounders is a bat-and-ball game played between two teams. Rounders is a striking and fielding team game that involves hitting a small, hard, leather-cased ball with a wooden, plastic, or metal bat that has a rounded end. The players score by running around the four bases on the field.
Softball is a popular variation of baseball, the difference being that it is played with a larger ball, on a smaller field, and with only underhand pitches permitted. Softball is played competitively at club levels, the college level, and the professional level. The game was first created in 1887 in Chicago by George Hancock.
A bunt is a batting technique in baseball or fastpitch softball. Official Baseball Rules define a bunt as follows: "A bunt is a batted ball not swung at, but intentionally met with the bat and tapped slowly within the infield." To bunt, the batter loosely holds the bat in front of home plate and intentionally taps the ball into play. A properly executed bunt will create weak contact with the ball and/or strategically direct it, forcing the infielders to make a difficult defensive play to record an out.
In baseball, an out occurs when the umpire rules a batter or baserunner out. When a batter or runner is out, they lose their ability to score a run and must return to the dugout until their next turn at bat. When three outs are recorded in a half-inning, the batting team's turn expires.
Throughout baseball's history, the rules have frequently changed as the game continues to evolve. A few typical rules most professional leagues have in common are that four balls are a base on balls, three strikes are a strikeout, and three outs end a half-inning.
A baseball field, also called a ball field or baseball diamond, is the field upon which the game of baseball is played. The term can also be used as a metonym for a baseball park. The term sandlot is sometimes used, although this usually refers to less organized venues for activities like sandlot ball.
In the sports of baseball and softball, a batted ball is a pitch that has been contacted by the batter's bat. Batted balls are either fair or foul, and can be characterized as a fly ball, pop-up, line drive, or ground ball. In baseball, a foul ball counts as a strike against the batter, unless there are already two strikes on the batter, with special rules applying to foul tips and foul bunts. Fly balls are those hit in an arcing manner, with pop-ups being a subset of fly balls that do not travel far. Line drives are batted balls hit on a straight line trajectory, while ground balls are hit at a low trajectory, contact the ground shortly after being hit, and then either roll or bounce. Batted balls, especially line drives, can present a hazard to players, umpires, and spectators, as people have been seriously injured or killed after being struck by batted balls.
Pesäpallo is a fast-moving bat-and-ball sport that is often referred to as the national sport of Finland and has some presence in other places including Germany, Sweden, Switzerland, Australia, and Canada's northern Ontario. It is similar to brännboll, rounders, lapta, and baseball.
In baseball, the rules state that a batted ball is considered in flight when it has not yet touched any object other than a fielder or his equipment. Such a ball can be caught by a fielder to put the batter out.
A ground rule double is a baseball rule that awards two bases from the time of pitch to all baserunners including the batter-runner, as a result of the ball leaving play after being hit fairly and leaving the field under a condition of the ground rules in effect at the field where the game is being played. An automatic double is the term used to refer to a fairly hit ball leaving the field in circumstances that do not merit a home run, such as when the ball's first bounce was within the field. The automatic double is commonly called a ground rule double.
In major league baseball, the dead-ball era refers to a period from about 1900 to 1920 in which run scoring was low and home runs were rare in comparison to the years that followed. In 1908, the major league batting average dropped to .239, and teams averaged just 3.4 runs per game, the lowest ever. Spacious ballparks limited hitting for power, and the ball itself was "dead" both by design and from overuse. Ball scuffing and adulteration by pitchers, particularly the spitball, were allowed, putting hitters at a disadvantage.
The Knickerbocker Rules are a set of baseball rules formalized by William R. Wheaton and William H. Tucker of the Knickerbocker Base Ball Club in 1845. They have previously been considered to be the basis for the rules of the modern game, although this is disputed. The rules are informally known as the "New York style" of baseball, as opposed to other variants such as the "Massachusetts Game" and "Philadelphia town ball".
Ground rules are rules applying to the field, objects on and near it, and special situations relating to them, in the game of baseball. Major League Baseball has defined a set of "universal ground rules" that apply to all MLB ballparks; individual ballparks have the latitude to set ground rules above and beyond the universal ground rules, as long as they do not directly contradict each other. Additionally, a set of universal ground rules exists for the six MLB stadiums with retractable roofs, with the individual ballparks able to set additional rules.
Vintage base ball is baseball presented as if being played by rules and customs from an earlier period in the sport's history. Games are typically played using rules and uniforms from the 19th century. Vintage base ball is not only a competitive game, but also a reenactment of baseball life similar to American Civil War reenactment. Players dress in uniforms appropriate to the time period, and many teams appear to be direct copies of teams that existed in the late 19th century. The styles and speech of the 19th century are also used while playing vintage base ball.
Bat-and-ball games, or safe haven games, are field games played by two opposing teams. Action starts when the defending team throws a ball at a dedicated player of the attacking team, who tries to hit it with a bat and then run between various safe areas in the field to score runs (points). The defending team can use the ball in various ways against the attacking team's players to force them off the field when they are not in safe zones, and thus prevent them from further scoring. The best known modern bat-and-ball games are cricket and baseball, with common roots in the 18th-century games played in England.
