Hit Distance represents the distance away from home plate that a batted ball lands -- whether by hitting the ground, the seats, the wall or a fielder's glove.
Average Hit Distance (aDST) is calculated by: the sum of all Hit Distances, divided by all Batted Ball Events.
Statcast can record Hit Distances at the moment a ball touches the ground or where a ball ultimately ends up. A batted ball's farthest distance relative to home plate arguably tells the most accurate story of a Batted Ball Event.
Watch: Statcast measures the exit velocity, launch angle and projected distance of Matt Chapman's homer.
