The Phillies optioned infielder Freddy Galvis to Triple-A Lehigh Valley following Thursday's game. Galvis went 0-for-3 with a walk and a run scored in the game, but is just 2-for-42 in 16 games this season.
Among the 386 major league players with at least 25 plate appearances, Galvis ranks last in the major leagues in hitting (.048), OBP (.109) and OPS (.156).
"He needs to go, play, get at-bats and gather himself a little bit," Sandberg said of Galvis, who missed the season's first two weeks while recovering from a MRSA infection. "He might have been rushed up here a little bit, with not having spring training."
"I missed a lot of games," Galvis said. "I missed a lot of at-bats. That's why I'm going down, you know? To get my at-bats, try to get my approach and try to swing the bat better."
The Phillies will make a corresponding roster move before Friday's game at Citi Field against the Mets.
