"Once they traded J.J. [Putz], I thought, I kept going back and forth and back and forth," he said, adding that he told the Mariners of his decision roughly a week ago. "I just felt like a big relief when I went back to the bullpen, because I feel that's like my home now. I've been there two years and I don't know if I could go back [to starting]."


And he has no plans to try. Morrow met with Mariners coaches and front-office members early Sunday; they are on-board with the decision and released relief pitcher Tyler Walker a few hours later.
