The infield fly [rule is a baseball](https://baseballshows.com/baseball-field-positions/) regulation that protects base runners from being put at risk during specific plays. It applies when a batter hits a pop-up that an infielder can catch with ordinary effort, ensuring that runners can stay on their bases without the threat of being doubled off.

## What is the Infield Fly Rule?

The [infield fly rule states](https://baseballshows.com/infield-vs-outfield-positions/) that if a batter hits a fair fly ball (excluding line drives or bunts) that can be caught by an infielder with ordinary effort, the umpire can call the batter out, regardless of whether the ball is caught. This rule prevents base runners from being forced to run when the ball is dropped, protecting them from the risk of being tagged out.

## When Does the Infield Fly Rule Apply?

The infield fly rule is invoked under specific conditions:

- There must be fewer than two outs.
- There must be runners on first and second base, or the bases must be loaded.
- The ball must be a fair fly ball that can be caught by an infielder.

For example, if there are runners on first and second with one out, and the batter hits a high pop-up that the shortstop can easily catch, the umpire can call the infield fly rule, declaring the batter out automatically. This allows the runners to remain on their bases without being forced to advance.

## What Are Common Misconceptions About the Infield Fly Rule?

A common misconception is that the infield fly rule applies to any high fly ball. In reality, the ball must be catchable with ordinary effort by an infielder, meaning it must be hit in a way that an infielder could reasonably be expected to catch it.

Another misconception is that the rule only applies when the ball is caught. However, once the rule is called, the batter is out regardless of whether the ball is caught. Fans sometimes believe that the rule is invoked incorrectly if the ball is dropped, but that is not the case if it meets the criteria.

## How Does the Infield Fly Rule Affect Gameplay?

The infield fly rule has strategic implications for both the offensive and defensive teams. For the offense, it provides security since the runners cannot be doubled off if the ball is dropped, allowing them to stay put and wait for the next play.

For the defense, understanding the rule affects their positioning and how aggressively they attempt to catch the ball. Knowing the rule is in effect may lead them to play it safe and ensure they make the catch rather than risk a potential error.
