A sacrifice bunt occurs when a player is successful in his attempt to advance a runner (or multiple runners) at least one base with a bunt. In this vein, the batter is sacrificing himself (giving up an out) in order to move another runner closer to scoring. When a batter bunts with a runner on third base, it is called a squeeze play and, if successful, is still recorded as a sacrifice.
A sacrifice bunt does not count against a player's batting average or on-base percentage, as the decision to sacrifice often isn't made by the player. Typically, a player will be given a sign by the third-base coach, instructing a bunt attempt. In National League ballparks, pitchers are frequently called upon to sacrifice bunt.
If an error is committed and the batter reaches base, he is still credited with a sacrifice. However, if the sacrifice bunt attempt turns into a single, the batter is simply credited with a hit and no sacrifice is given. An official scorer may determine that a batter was exclusively trying to bunt for a base hit and choose not to give him credit for a sacrifice. However, this is rare in sacrifice situations (with less than two outs and men on base).
