A bunt is a special type of offensive technique in baseball or fastpitch softball. In a bunt play, the batter loosely holds the bat in front of the plate and intentionally taps the ball into play.
The primary goal in bunting is to ground the ball into fair territory, as far from the fielders as possible, generally while staying within the infield. This requires not only physical dexterity and concentration, but also a knowledge of the fielders' positions, their relation to the baserunner or baserunners, their likely response to the bunt, and knowledge of the pitcher's most likely pitches.
The bunt is often characterized by the batter turning his body toward the pitcher and sliding one hand up the barrel of the bat to help steady it. This is called squaring up. Depending on the type of bunt, the batter might square well before the pitcher begins throwing, or as the pitch is being batted.
In a sacrifice bunt, the batter will put the ball into play with the intention of advancing a baserunner, in exchange for the batter being thrown out. The sacrifice bunt is most often used to advance a runner from first to second base, although the runner may also be advanced from second to third base, or from third to home. The sacrifice bunt is most often used in close, low-scoring games, and it is usually performed by weaker hitters, especially by pitchers in games played in National League parks. A sacrifice bunt is not counted as an at-bat. In general, when sacrifice bunting, a batter will square to bunt well before the pitcher releases the ball.
