Baseball statistics play an important role in evaluating the progress of a player or team.
In baseball, an earned run is any run that was fully enabled by the offensive team's production in the face of competent play from the defensive team. Conversely, an unearned run is a run that would not have been scored without the aid of an error or a passed ball committed by the defense.
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 stolen base occurs when a runner advances to a base unaided by other actions and the official scorer rules that the advance should be credited to the action of the runner. The umpires determine whether the runner is safe or out at the next base, but the official scorer rules on the question of credit or blame for the advance under Rule 10 of the MLB's Official Rules.
Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding team, called the pitcher, throws a ball that a player on the batting team, called the batter, tries to hit with a bat. The objective of the offensive team is to hit the ball into the field of play, away from the other team's players, allowing its players to run the bases, having them advance counter-clockwise around four bases to score what are called "runs". The objective of the defensive team is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate.
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 game similar to baseball played with a larger ball on a smaller field, 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 first baseman, abbreviated 1B, is the player on a baseball or softball team who fields the area nearest first base, the first of four bases a baserunner must touch in succession to score a run. The first baseman is responsible for the majority of plays made at that base. In the numbering system used to record defensive plays, the first baseman is assigned the number 3.
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 the history of baseball the rules have frequently changed as the game has continued to evolve. The rules of baseball can vary slightly from league to league, with there being dozens of leagues worldwide. A few common rules most professional leagues have in common is that 4 balls is a Base on balls, 3 strikes is a strikeout and 3 outs ends a half inning. One example of differing rules in professional leagues is in Major League Baseball a pitch clock is in place to speed up the pace of the game by forcing pitchers to pitch in a 15-20 second window, where in the Nippon Professional Baseball League no such rule exists.
Baseball and cricket are the best-known members of a family of related bat-and-ball games. Both have fields that are 400 feet (120 m) or more in diameter between their furthest endpoints, offensive players who can hit a thrown/"bowled" ball out of the field and run between safe areas to score runs (points) at the risk of being gotten out, and have a major game format lasting about 3 hours.
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.
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 countries including Germany, Sweden, Switzerland, Australia, and Canada's northern Ontario. The game is similar to brännboll, rounders, and lapta, as well as baseball.
A hit and run is a high risk, high reward offensive strategy used in baseball. It uses a stolen base attempt to try to place the defending infielders out of position for an attempted base hit.
Baseball scorekeeping is the practice of recording the details of a baseball game as it unfolds. Professional baseball leagues hire official scorers to keep an official record of each game, but many fans keep score as well for their own enjoyment. Scorekeeping is usually done on a printed scorecard and, while official scorers must adhere precisely to one of the few different scorekeeping notations, most fans exercise some amount of creativity and adopt their own symbols and styles.
Bat-and-ball 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 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.
Old cat games were bat-and-ball, safe haven games played in North America. The games were numbered according to the number of bases. The number of bases varied according to the number of players. Only one old cat continues to be commonly played in the 21st century.
