The Mariners have designated righty Logan Bawcom for assignment, the team announced via press release. His 40-man spot will go to the just-acquired Justin Ruggiano.
Bawcom, 26, worked to a 4.93 ERA in 45 2/3 Triple-A innings last year, with 6.3 K/9 against 4.9 BB/9. Of course, he was throwing in the notoriously hitter-friendly PCL, but he was coming off a year in which he had put up a 2.91 earned run mark in the same league, with better strikeout (8.9 K/9) and walk (3.3 BB/9) numbers.
