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 (or rule-book double) is commonly called a ground rule double. [1]
Major League Baseball (MLB) has a set of universal ground rules that apply at all ballparks, two of which award two bases to the batter and any baserunners: [2]
Two bases can also be awarded per home park ground rules—rules created to provide for unique playing conditions of a specific ballpark. For example, ground rules govern the situation when a batted ball is lodged in the ivy at Wrigley Field, [3] or the walkways near the ceiling of Tropicana Field, a domed stadium. [4]
The far more commonly occurring automatic double results from the generally applicable MLB rules 5.05(a)(6) through 5.05(a)(9). [5] : 22–23 These rules govern how to treat the batter (and any runners on base) when a batted ball is hit fair but passes out of the field of play or becomes artificially obstructed while in the field of play. For example, these rules cover balls that hit the ground in fair territory and land out of play, typically by bouncing over a fence or wall in the outfield. The rules also provide generically for the award of a double when a batted ball goes through or under a fence; and when it goes through or sticks in shrubbery or vines on the fence.
MLB rule 5.05(a)(9) governs when fair fly balls are deflected into the stands by a fielder: "Any fair fly ball is deflected by the fielder into the stands, or over the fence into foul territory, in which case the batter shall be entitled to advance to second base; but if deflected into the stands or over the fence in fair territory, the batter shall be entitled to a home run. However, should such a fair fly be deflected at a point less than 250 feet (76 m) from home plate, the batter shall be entitled to two bases only." [5] : 23
When two bases are awarded by either ground rules or the automatic rule, any baserunners ahead of the batter are entitled to advance two bases from their positions at the time of pitch. Only in the case of interference is the umpire vested with discretion to award more bases (see MLB rule 6.01). [5] : 63–69 Application of the ground rule or automatic double rule can result in a runner at first base, who appears to have been able to score on a batted ball, being required to return to third base due to the ball going out of play. [6] [7]
In the early years of baseball, batted balls that cleared the fence in fair territory on the fly or after a bounce were counted as home runs. The rule was changed by the American League before the 1929 season and by the National League before the 1931 season. [8] [9] Baseball records did not differentiate between home runs that cleared the fence on the fly and those that bounced over. Notably, this includes most of Babe Ruth's career, including when he hit 60 home runs in 1927, although there is no evidence any of Ruth’s home runs bounced before going over the fence. [10] The last "bounce" home run in MLB was hit by Al López of the Brooklyn Robins on September 12, 1930, at Ebbets Field. [8]
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 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.
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.
In baseball, an inside-the-park home run is a rare play in which a batter rounds all four bases for a home run without the baseball leaving the field of play. It is also known as an "inside-the-parker", "in-the-park home run", or "in-the-park homer".
In baseball, a foul ball is a batted ball that:
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 common 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 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.
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.
In sports, offense or offence, known as attack outside of North America, is the action of attacking or engaging an opposing team with the objective of scoring points or goals. The term may refer to the tactics involved in offense, or a sub-team whose primary responsibility is offense.
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.
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.

The 1931 major league baseball season began on April 14, 1931. The regular season ended on September 27, with the St. Louis Cardinals and Philadelphia Athletics as the regular season champions of the National League and American League, respectively. The postseason began with Game 1 of the 28th World Series on October 1 and ended with Game 7 on October 10.

In baseball, base running is the act of running from base to base, performed by members of the team at bat.
Baseball5 (B5) is an internationally played safe haven game with many of the same rules as baseball and softball, which is governed alongside those sports by the World Baseball Softball Confederation (WBSC).
