Royals manager Ned Yost said he did not know at first if Escobar had sustained a strain or pull of the calf, but he did not believe the injury to be serious.
"He thought it was a cramp. We'll come in, if he feels any tightness in there tomorrow, probably give him a day off," Yost said. "But if not, we'll roll him out there."
