Mariners transferred RHP Cooper Criswell to the 60-day injured list.
Nothing has changed in the prognosis for Criswell, who is still sidelined indefinitely with a right shoulder strain, this was done as a procedural move to clear a spot on the club’s 40-man roster for the addition of Miles Mastrobuoni on Friday. Criswell now won’t be eligible to return from the injured list until the beginning of August.
