In baseball, a barrel is a term used to describe a well-struck ball where the combination of exit velocity and launch angle generally leads to a minimum .500 batting average and 1.500 slugging percentage. The term was introduced by Statcast, a technology used to track player and ball movements during games. To be considered a barrel, a batted ball requires an exit velocity of at least 98 mph, and the range of launch angles expands as the exit velocity increases. Barrels are a high-value type of hit, and collecting them tends to lead to good outcomes. A player with a 15 percent barrel rate or higher is considered elite when looking at a hitter’s profile.
