Caminero was removed from Game 4 of the World Series against Milwaukee on Tuesday due to an apparent leg injury.
Caminero seemed to tweak something while reaching base on an error in the 12th inning, and he later limped off the field after advancing to third base on a Liam Hicks single. The Rays were able to rally in extra innings and force a Game 5, though it remains to be seen whether Caminero will be healthy enough to play Wednesday.
