Baseball Fly Ball

In baseball, a fly ball is a term used to describe a type of batted ball. It is one of three main terms used to describe types of batted balls, with the other two being line drives and ground balls. Below we will cover everything you need to know about fly balls.


What is a Fly Ball?

A fly ball is when a batter hits the ball in the air. The fielders will run to the ball attempting to catch it before it hits the ground. If the catch is made, the batter is ruled out. Fly balls are an extremely common way to record outs in baseball, and some pitchers may focus on getting hitters to hit soft fly ball outs. These pitchers are known as "fly ball pitchers."

Types of Fly Balls

Fly ball is the basic term to describe any type of ball hit in the air. Specific types of fly balls have their own names. The two main types of fly balls are the pop fly and the sacrifice fly.

Pop Fly

A pop fly, also known as a pop up, is a type of fly ball. The difference is a pop fly goes much higher in the air, and travels a shorter distance from home plate. Generally, a fly ball is hit to the outfield, while a pop fly is hit to the infield. Because of this, it is common to see infielders catch pop flys.

Sacrifice Fly

A sacrifice fly is a unique type of fly ball that allows a runner to advance and score from third base by tagging up. The sacrifice fly (often called a sac fly) is a huge part of offense and scoring runs in the MLB.

Fielding Fly Balls

Fielding fly balls is a major part of a defensive player's job in baseball. In order to properly field a fly ball, you need to be able to judge a ball's path traveling through the air in the moment and run towards the part of the field where it's going to land. Fielders will then want to try to line themselves up so that the ball is right in front of them, allowing them to step forward while they catch the ball and get ready to throw. This will help protect against runners tagging up, and even scoring a run.

Tagging Up

Baserunners may try to advance at their own risk whether or not a fly ball is caught. However, if a baseball is caught on the fly, the runner must tag up by touching the base they occupy and taking off for the next base once the ball has landed in the defender's glove. It is common to see runners tag up on fly balls that are hit deeper into the outfield.

Foul Fly Balls

Any fly ball that is caught by a fielder in foul territory is not considered a foul ball. Instead, it is considered a fly ball out, and the rules of a normal fly out remain the same. While this can be a benefit to the defending team, since they can record outs on foul balls, outfielders still have to keep an eye out for runners tagging up and be ready to throw.

FAQ

Can you run on a fly ball in baseball?

Runners should use their judgement when a fly ball is hit. They can choose to run, but if the ball is caught by a fielder, they must return to their base. If the fielder throws the ball to the base before the runner can return, the runner will be ruled out.

Can you intentionally drop a fly ball?

If it appears that a fielder intentionally dropped a fly ball, the umpire will use their discretion to rule if it is an out.
