The barrel is a technical term used in baseball to describe batted-ball events with the metrics of .500 batting average and 1.500 slugging percentage. Barrel classification was implemented in Major League Baseball in 2015. For teams to be barreled, the ball should have a minimum velocity of 98mph between a 26-30 degrees angle. Whenever the batted ball reaches beyond 98 mph, its range and angle also expand.
Example of Barrel
Consider a ball traveling with an exit velocity of 100 mph. If so, it already reached and leveled to the barrel classification, and its angle should be around 25-31 degrees. If the ball’s velocity had reached more than 100 mph, then its range and angle should also change to at least 26-33 degrees. This only means that in every additional velocity, the range will increase at least two degrees until the maximum 116mph is achieved. Given the 116 mph threshold, the Barreled designation will be having an expected launch angle between 8 - 50 degrees.
What are the Highest-Value Batted Balls?
When getting the batting average and slugging percentage, the match official should know to determine the exact number of the ball’s exit velocity and launch, so they can find out whose players have mashed the most. In a Major League Baseball set up, the batting average of the ball that reached 100 mph is around .626 batting average. With the correct measurement of the exit velocity and launch angle, it would result in a correct way of batting.
The Barrel Zone
The barrel zone is where the 98 mph of 26 - 30 degrees begins. When the ball’s speed is higher, it’s expected that its range would also expand wider so it can be considered a barrel. With the exit velocity beyond 99 mph of about 25 -33 degrees, the ball’s impact gets harder. When the player gets the minimum barrel classification, then the outlining and the batted-ball types are expected to be in order. To achieve this, the batter should manually and instinctively calculate the ball's distance and the force he has to apply to the ball, so he'll know the exit velocity and the launch angle. By then, he'll know he's doing the right thing.
