Walker (shoulder) was released by Atlanta on Friday.

EDGE Analysis

The move clears space on the 40-man roster for Travis Demeritte, who was claimed off waivers from the Tigers in a corresponding move. Walker threw 9.1 innings in his big-league debut, allowing just two runs but posting an unimpressive 6:4 K:BB. He missed all of last season due to shoulder issues, though it's unclear whether or not those are still present or whether they factored into Atlanta's decision to let him go.
