Demystifying the Infield Fly Rule: Protecting Fairness in Baseball

Infield Fly Rule: What You Need to Know

As a baseball fan, you’ve probably heard the term “infield fly rule” mentioned many times. But do you really understand what it means?

In this article, we’ll give you a comprehensive overview of the infield fly rule, how it works, and why it’s an essential part of baseball.

Overview of Infield Fly Rule

When less than two outs occur in a baseball game and there are runners on base, the defense can use a particular strategy to gain an advantage, known as the double play. It involves catching a fly ball hit by the batter and then immediately throwing it to another fielder to tag out a baserunner before they return to their base.

However, such a strategy can put the batter at a severe disadvantage, as they may lose the chance to score or accumulate hits. Therefore, to protect the baserunners’ safety and give the batter a fair shot, the infield fly rule comes into play.

To be eligible for the infield fly rule, three conditions must be met. Firstly, a fly ball must be hit, which is convertible into an out, with ordinary effort.

Secondly, the ball must be flying within the infield. Thirdly, there must be at least one runner on base, with less than two outs in the inning.

Once the umpire calls the infield fly rule, the batter is automatically out, whether the ball is caught or not. It means that the defense can’t take advantage of the double or triple play strategy by deliberately dropping or not catching the ball and instead going for a double or triple play.

Purpose and Function of Infield Fly Rule

The primary purpose of the infield fly rule is to protect baserunners from being trapped out by the defense while trying to advance to another base. Imagine this scenario: If there’s a runner on first base with less than two outs, and the batter hits a high fly ball in the vicinity of the shortstop and second base, which is easily catchable, but the defense decides to let it fall intentionally.

The defense can then throw the ball to second base to tag out the runner who’ll try to advance on the next play. This can result in a double play and the end of the inning.

However, implementing the infield fly rule prevents such occurrences where the defense can try to trap the runner out by catching the ball, either intentionally or unintentionally. Without the rule, the batter would face a severe disadvantage and thereby affect the overall fairness of the game.

How Infield Fly Works

To illustrate how the infield fly rule works, let’s take the example of a game between the Baltimore Orioles and the Atlanta Braves. The Braves have a runner on first base, and the batter hits a high pop-up in the infield.

The shortstop calls for the ball and catches it quickly, and the umpire makes the call. The infield fly rule is in effect, and the batter is out.

While the ball is in the air, the runner on first base can’t advance. It means that the baserunner cannot try to steal or go to the second base while there’s a possibility of the fielder catching the ball.

The baserunner must stay put until the fielder either catches the ball or lets it drop, after which they can try to advance. If the baserunner decides to advance before the fielder catches the ball, they will have to return to their base and tag up once the ball is caught.

If the baserunner leaves their base before the ball is caught, they can be caught in a double play, just like in any other situation where the ball is in play.


The infield fly rule is an essential aspect of baseball. It protects the baserunners by preventing the defense from unfairly trapping them out while trying to advance.

It also serves to keep the game fair by giving the batter a chance to get a hit or score, irrespective of the defense’s strategy. As a fan or player of baseball, understanding the infield fly rule is crucial for comprehending and appreciating the game’s nuances.
