In the top half of the inning, Rafael Ynoa hit a sinking liner to left and Peralta attempted to make a sliding catch. The ball and his glove got caught underneath him, bending his wrist backward.
After being examined by assistant trainer Ryan DiPanfilo, Peralta remained in the game, but was removed for a pinch-hitter in the bottom half of the inning.
Peralta will be examined Friday by a team doctor, but he was relieved when the X-ray results came back.
"My glove got stuck in the grass and my wrist went all the way back and I felt it was broken for sure," Peralta said. "That's why I dropped the glove and held my hand. Thank God, nothing is broke, it's just extremely sore."
