The Mariners shuffled their roster on Friday, respectively swapping outfielder Seth Smith and right-hander Nate Karns in separate trades for right-hander Yovani Gallardo and outfielder Jarrod Dyson. Even after making those moves, however, Ken Rosenthal of FOX Sports writes that Seattle would still like to add another bullpen arm. He also notes that the Mariners plan to use a “revolving door” approach to the fifth spot in their rotation and are open to adding some inexpensive depth to accompany current candidates Ariel Miranda, Rob Whalen and Chris Heston.
