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.
Softball is a sport similar to baseball, and 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.
In baseball, a triple play is the act of making three outs during the same play. There have only been 735 triple plays in Major League Baseball (MLB) since 1876, an average of just over five per season.
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.
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 continues to evolve. A few common rules most professional leagues have in common is that four balls is a base on balls, three strikes is a strikeout, and three outs end a half-inning.
In baseball, a force play is a situation in which a base-runner is compelled to vacate their starting base and attempt to advance to the next base. When a runner is forced to advance to a base, they are forced out if an opponent with possession of the ball reaches that base before they do. Runners are no longer forced to advance to the next base if any runner behind them on the base-paths is put out.
In baseball and softball, a tag out, sometimes just called a tag, is a play in which a baserunner is out because a fielder touches him with the ball or with the hand or glove holding the ball, while the ball is live and the runner is in jeopardy of being put out – usually when he is not touching a base.
In baseball, an appeal play occurs when a member of the defensive team calls the attention of an umpire to an infraction which he would otherwise ignore.
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 baseball, obstruction is when a fielder illegally hinders a baserunner running within the basepath. Baserunners are generally permitted to run from base to base without being physically blocked or hindered by a fielder. The only time that a fielder is not obligated to "get out of the way" of a baserunner is when the fielder is fielding a hit ball or in possession of the ball.
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 baseball, a fourth out is a legal out made by the defense after three outs in a half-inning have already been made. According to the rules, the third out does not cause the ball to become dead; if the fielders make a subsequent out that prevents a run from scoring, this out will supersede the apparent third out, thus becoming the recorded third out. For statistical purposes, the apparent third out is "undone" and the fourth out's result is recorded instead. With the advent of video replay appeals, a new rationale for making extra out(s) has emerged: insurance against a prior out being undone on appeal. These fourth-out situations are not the same as four strikeouts in an inning.
