The Mariners have designated righty Casey Fien for assignment, per a team announcement. Seattle has also placed infielder Shawn O’Malley on the 60-day DL to clear another 40-man spot.
These moves were designed to open the door to two new members of the big league bullpen. The M’s purchased the contracts of righties Jean Machi and Emilio Pagan. First baseman Dan Vogelbach was optioned to open another active roster spot.
