SF: Definition and Origin


What does SF stand for in baseball? The SF slang stands for a sacrifice fly. This rule depends on a hitter’s decision to hit a fly ball to the outfield or foul territory.

  • A sacrifice fly may be erroneous, but it is primarily done intentionally. When intentionally done, the batter aims to help the team’s runner to score. Also, the hitter is credited with a Runs Batted In, or RBI.
  • If an error occurs and the ball is dropped, a sacrifice fly would still be credited as long as the game officials find that the runner would still have scored either way.
  • Another rare occurrence is when a hitter can score a sacrifice fly in baseball from third base. This would happen if the fielder catches the ball anywhere else on the field. Unfortunately, you would not see this happen much as the SF usually lands the ball very close to the home plate.

The sacrifice fly rule started being adopted in the legitimate baseball rules back in 1954. Here, it was clearly distinguished from the bunt. Before then, game officials used to be perplexed about whether a sacrifice fly has statistical value to the game.

Now, we enjoy a more clearly stipulated rule regarding the sac fly!

What is SF Used for?


After diving into the sacrifice fly baseball definition, what is the rationale for choosing to do it over trying to achieve a home run?

This move is termed a “sacrifice” because the hitter knows that doing this will compromise their chances to score a run. In essence, the player sacrifices their chance to score a run to give their teammate the chance to score.

How Does It Work?


The sacrifice fly is mentioned in baseball rules in Rule 9.08D. This mentions that a sac fly is scored when the batter hits a ball and is caught, and the runner scores.

Or, a sacrifice fly can also be scored when the hit ball is dropped and the runner scores.

Does a Sac Fly Count as an at-bat?


A sacrifice fly will not be counted as an at-bat. This is the case because a hitter will do his best to hit a fly ball when he has less than two outs. He may do so by sacrificing his at-bat to score the run.

Also, will a sac fly count in batting average? Unfortunately, it will not be counted to avoid giving a penalty to the hitters for successfully doing the sacrifice.

Even though a sacrifice fly does not affect the batting average of the player, it will still count on their plate appearance and consequently lowers the on-base percentage of the player.

This is in stark contrast with a sacrifice bunt, where it does not affect the on-base percentage calculation of the player.
