Major League Baseball is testing defensive-positioning restrictions in the Arizona Fall League, according to a report cited by Fox News’ OutKick. The trial may help the league assess whether limiting where fielders can set up leads to more hits and improves the viewing experience.

The report says markers have been placed on the field as reference points for defensive positioning. Hawkeye tracking technology monitors players’ locations, while display boards indicate whether they are within the designated limits. The account describes infielders as playing more directly in their usual positions and outfielders as positioned closer to the foul lines, with the center fielder playing shallower than is common in the major leagues.

The test comes amid discussion about declining offensive production and how defensive positioning may affect outcomes on balls hit in the air. The source argues that modern data-driven positioning has made it harder for well-struck fly balls and line drives to become hits. It also points to a play in a National League Championship Series game between the Los Angeles Dodgers and Milwaukee Brewers as an example of a well-hit ball being caught by an outfielder positioned in the right spot.

The source characterizes the Arizona Fall League as a potential testing ground for rule changes, but the supplied material does not indicate that MLB has decided to apply these restrictions to major-league games. Any effect on scoring or future rules remains uncertain.
