The move is retroactive to Thursday, a day after Gregorius and outfielder Kyle Schwarber collided on a single to short left in the seventh inning of an eventual 2-1 loss to the Texas Rangers. Gregorius' leg appeared to hit Schwarber in the face, but both stayed in the game.
In his third season with the Phillies, Gregorius has a slash line of .288/.338/.356 with seven RBIs.
In a corresponding roster move, the Phillies have recalled infielder Bryson Stott from Triple-A Lehigh Valley.
