Sacrifice fly

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)
