MLB experiments with new outfield positioning in Arizona Fall League
Summary

Major League Baseball is testing new outfield positioning rules during the Arizona Fall League. Outfielders are required to align themselves with field markings prior to pitches, and infielders must do so when no runners are on base, as part of an initiative to boost offensive performance. This preliminary testing, which includes the use of the Hawkeye system to monitor adherence, is still in the early stages. Further developments will be necessary before any implementation in the major leagues can occur.
