Royals catcher Salvador Perez left Thursday's game due to "mild dizziness."
The move was considered precautionary, though it's worrisome that Perez was dealing with dizziness considering he had a concussion earlier this year. Classifying the injury as "mild" could imply the team doesn't believe it's too serious. But concussion-related issues are always difficult to project.
Perez is hitting .281/.315/.412 in 417 at-bats.
