This page displays the percentage of plate appearances where a defensive team was shifted (through the 2022 season) or shaded (starting from the 2023 season).
A shift is defined as when three or more infielders are on the same side of second base.
A fielder is shaded when they are positioned outside of their typical responsible slices of the field. Those slices are represented in this image.
