Galvis' demotion did not come as a surprise. He went 0-for-3 with one walk and one strikeout Thursday. Galvis is hitting .048 (2-for-42) with one RBI, three walks and 12 strikeouts in 16 games.
"He needs to go play, get at-bats and gather himself a little bit," Phils manager Ryne Sandberg said. "He might have been rushed up here a little bit, with not having Spring Training."
Galvis missed some time in March when he suffered a MRSA infection in his left knee.
"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. I don't feel sad. I don't feel bad or nothing. I'm just going to go there and work on my hitting. That's it."
