MLB Experiments With Restricted Outfield Shifts in Arizona Fall League

A recent Arizona Fall League game at Salt River Fields featured an AFL-record five triples as MLB tests new outfield shift restrictions.

Scottsdale defeated Salt River 15-8 in a recent Arizona Fall League matchup that set a league record with five triples. The high-scoring contest occurred at Salt River Fields, where Major League Baseball is currently testing restricted outfield shifts to increase extra-base hits. Under these experimental rules, outfielders must play more shallow than traditional positioning, a change Minnesota Twins prospect Kyle DeBarge noted has turned potential doubles into triples.

Players at Salt River Fields must consult a small videoboard to verify their defensive alignment for every at-bat. The technology displays an "O" if a fielder is in an acceptable spot or an "X" if they are incorrectly positioned. According to Salt River manager Ted Tom, the system is designed to prevent outfielders from adjusting for individual hitter tendencies, forcing them to play "straight up" and move backward on fly balls more frequently.

MLB is utilizing the AFL to address stagnant offensive statistics. While the pitch clock reduced game times by approximately 25 minutes, other metrics have shown minimal growth; league-wide batting averages were .243 in 2022 compared to .244 in 2026, while hits per game rose slightly from 8.16 to 8.20 in that same span. Although the new rules have virtually eliminated bloop singles in the testing environment, any potential implementation at the Major League level remains years away.
