What happened: The Kansas City Royals have selected the contract of veteran catcher Luke Maile, adding him to the active roster. To make room, the club designated right-hander Eric Cerantola for assignment.

Why it matters: The move gives Kansas City an experienced backup option behind the plate, a low-cost depth play for a club sitting at 35-52 and well out of contention. Cerantola's designation opens a 40-man roster spot and puts his future with the organization in question.

What to watch: Watch whether Cerantola clears waivers and is outrighted or claimed by another club, and how Maile factors into the catching rotation.
