In baseball, a batted ball is considered a sacrifice fly (denoted by SF) if the following four criteria are met:

  • There are fewer than two outs.
  • The ball is hit to the outfield.
  • The batter is out, either caught or put out at first base, or would have been out except for an error.
  • A runner that is already on base scores on the play.

A sacrifice fly is not counted as an at bat.

(see Rule 10 of Major League Baseball)
