Major League Baseball is instituting a new positioning rule for the 2023 season designed to limit the extreme infield shifting that has become increasingly common in the last decade.
Under the new rule, defenses must have two infielders on each side of second base and all infielders standing in the infield dirt when the pitcher is on the rubber. As a result, the overshift commonly used against left-handed hitters, which features three infielders on the right side of the field and often one stationed in short right field, will be illegal.
Due to this change, some pull-heavy sluggers could see a noticeable uptick in their performance.
