"It was really precautionary," manager Ned Yost said of Perez's removal from the game. "It was just a bit of a bruise, but he's fine. If it was in the season, we wouldn't even think twice about it."
Adam Moore pinch-hit for Perez in the top of the third inning, and he drew a walk and scored in the Royals' five-run inning. He then replaced Perez behind the plate.
"He was fine," pitcher James Shields said of Perez. "I just told him, 'Get out of here; there's no sense going back in the game.' He wanted to come back in, but it's Spring Training, and there's no sense to push anything. He just had a little foul tip, and everything should be fine."
If anything, the bruise might bother Perez when he hits.
"It's down on his bottom hand [on the bat] where you swing and [touch] the knob," Yost said. "But it's just [nothing]."
