The Rockies are calling up Elías Díaz from Triple-A Omaha, according to EL Extrabase.

With Salvador Perez and Carter Jensen both playing regularly, a third catcher makes sense for the Royals. Unless someone is hurt, we assume Tyler Tolbert will be swapped out. A utilityman on the roster for his speed, he’s 0-for-4 on the season. The Royals will also have to free up a spot on the 40-man.
