The A's have designated left-hander Jerry Blevins for assignment, according to the team's official Twitter feed. Adam Rosales was called up from Triple-A in a corresponding move. Credit the San Francisco Chronicle's Susan Slusser with the scoop, as she heard from Blevins himself (Twitter link) that he was on the move.
This is the third time Blevins has been DFA'ed this season and he hasn't been claimed due to his unique optional waivers situation. The 27-year-old has a 3.93 ERA and an 8.3 K/9 ratio in 17 appearances with the Athletics this year but has struggled with his control — Blevins' 6.9 BB/9 rate is almost twice his career average.
