The Philadelphia Phillies are planning to use unique outfield shifts based on the hitter's batted ball tendencies this season under new manager Gabe Kapler.

Matt Gelb of The Athletic wrote about the details:

"The Phillies have used the Grapefruit League games to implement their aggressive outfield shifting for every batter, based on spray charts. But they will go beyond that, flipping players across the field when the numbers tell them it is wisest.

That is why Rhys Hoskins, who will move from first base to left field this season, has begun some light work in right field. The Phillies hope Hoskins can be a passable defender in left field. But they know he lacks range and instincts because it is a new position for him. He will be their worst outfield defender. So Hoskins expects some mid-inning position changes when the data is clear."

Typically, teams shift outfielders toward one side of the field. The Phillies are planning to have outfielders change positions to put the superior defender in a specific spot.
