The procedural move frees up a spot on Washington’s 40-man roster for prospect Yohandy Morales. Millas hit the injured list with a left index finger fracture back in mid-July.

The move is retroactive to July 12th. The Nationals will need to add a back-up catcher to the roster before Friday.

Millas was struck by his own helmet after it fell off on a head-first slide into third base. He was left with a bloody lip and wound up leaving the contest. Keibert Ruiz took over behind the plate.
