MLB tests outfield positioning restrictions in Arizona Fall League

Major League Baseball is utilizing the Arizona Fall League as a testing ground for new defensive regulations. Following previous experiments with the pitch clock and infield shift restrictions, the league is currently testing restrictions on outfield positioning. The experiment reportedly involves requiring corner outfielders to play relatively shallow and remain within a specific distance of their respective foul lines.

In addition to rule testing, the league serves as a developmental platform for top prospects. Chicago White Sox prospects, including Caleb Bonemer, are using the season to refine specific skills, such as Bonemer transitioning to the outfield. Other organizations, including the Detroit Tigers, are also monitoring the progress of various prospects participating in the five-week schedule.
