Barrera's contract was selected by the Cardinals on Saturday.
Barrera is a 28-year-old backstop with a career .231/.317/.315 slash line in 51 major-league games. The Cardinals didn't send down any catchers as part of the series of moves which accompanied Barrera's call-up, but with the team moving Willson Contreras out from behind the plate for at least the near future, Barrera may serve as Andrew Knizner's backup.
