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.
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.
The infield fly rule is a rule of baseball and softball that treats certain fly balls as though caught, before the ball is caught, even if the infielder fails to catch it or drops it on purpose. The umpire's declaration of an infield fly means that the batter is out regardless of whether the ball is caught. The rule exists solely to prevent the defense from executing a double play or triple play by deliberately failing to catch a ball that an infielder could catch with ordinary effort.
Dead ball is a term in many ball sports in which the ball is deemed temporarily not playable, and no movement may be made with it. Depending on the sport, this event may be quite routine, or more uncommon.
In baseball, a foul ball is a batted ball that:
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.
In baseball, interference occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules.
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.
The New York Knickerbockers were one of the first organized baseball teams which played under a set of rules similar to the game today. Founded as the Knickerbocker Base Ball Club by Alexander Cartwright in 1845, the team remained active until the early 1870s.
Instant replay or action replay is a video reproduction of something that recently occurred, both shot and broadcast live.
The rules of basketball are the rules and regulations that govern the play, officiating, equipment and procedures of basketball. While many of the basic rules are uniform throughout the world, variations do exist. Most leagues or governing bodies in North America, the most important of which are the National Basketball Association and NCAA, formulate their own rules. In addition, the Technical Commission of the International Basketball Federation (FIBA) determines rules for international play; most leagues outside North America use the complete FIBA ruleset.
In sports, an ejection is the removal of a participant from a contest due to a violation of the sport's rules. The exact violations that lead to an ejection vary depending upon the sport, but common causes for ejection include unsportsmanlike conduct, violent acts against another participant that are beyond the sport's generally accepted standards for such acts, abuse against officials, violations of the sport's rules that the contest official deems to be egregious, or the use of an illegal substance to better a player's game. Most sports have provisions that allow players to be ejected, and many allow for the ejection of coaches, managers, or other non-playing personnel. In sports that use penalty cards, a red card is often used to signal dismissals. In some sports, another player is permitted to enter the game in place of the player who has been ejected, but in others the team is required to continue the game with a reduced number of players.

Delay of game is an action in a sports game in which a player or team deliberately stalls the game, usually with the intention of using the delay to its advantage. In some sports, the delay of game is considered an infraction if it is longer than that permitted according to the game's rules, in which case a penalty can be issued. Some sports that have a delay of game penalty are American football, Canadian football, ice hockey and association football.
Flood v. Kuhn, 407 U.S. 258 (1972), was a decision by the Supreme Court of the United States that preserved the reserve clause in Major League Baseball (MLB) players' contracts. By a 5–3 margin, the Court reaffirmed the antitrust exemption that had been granted to professional baseball in 1922 under Federal Baseball Club v. National League, and previously affirmed by Toolson v. New York Yankees, Inc. in 1953. While the majority believed that baseball's antitrust exemption was anomalous compared to other professional sports, it held that any changes to the exemption should be made through Congress and not the courts.
Toolson v. New York Yankees, 346 U.S. 356 (1953), is a United States Supreme Court case in which the Court upheld, 7–2, the antitrust exemption first granted to Major League Baseball (MLB) three decades earlier in Federal Baseball Club v. National League. It was also the first challenge to the reserve clause which prevented free agency, and one of the first cases heard and decided by the Warren Court.
In sports, out of bounds refers to being outside the playing boundaries of the field. The legality of going out of bounds, and the ease of prevention, vary by sport. Sports that use this term include American football, Canadian football, field lacrosse, basketball, rugby union, rugby league, and association football.
"The Common Law Origins of the Infield Fly Rule" is the title of an article by William S. Stevens published in 1975 in the University of Pennsylvania Law Review analyzing the infield fly rule. The brief eight-page article has vastly surpassed its modest original context, having been cited in federal and state judicial opinions and more than 100 works of legal literature. It has been included in a number of anthologies of baseball law, and prompted copycat and parody articles. The New York Times called the article "one of the most celebrated and imitated analyses in American legal history".
In American tort law, the Baseball Rule is an exculpatory clause applicable to baseball games with spectators; it holds that a baseball team or its sponsoring organization cannot be held liable for injuries suffered by a spectator struck by a foul ball batted into the stands, under most circumstances, as long as the team has offered some protected seating in the areas where foul balls are most likely to cause injuries. This is considered within the standard of reasonable care that teams owe to spectators, although in recent decades it has more often been characterized as a limited- or no-duty rule, and applied to ice hockey and golf as well. It is largely a matter of case law in state courts, although four states have codified it.
