The Diamondbacks have designated righty Kevin Munson for assignment, Zach Buchanan of AZCentral.com tweets. Munson is a 26-year-old reliever who has yet to see MLB action.
After being by the Phillies in last year’s Rule 5 draft, Munson was sent back to Arizona in mid-March. Since that time, he’s posted some uneven results at the Triple-A level.
Munson looked like a future piece last year, running up 62 1/3 innings of 2.60 ERA ball with 11.8 K/9 against 3.2 BB/9. But he’s reversed course in 2015 after experiencing arm soreness in the spring. Over his 31 1/3 frames at the highest level of the minors, Munson has issued 7.2 walks to go with only 8.6 strikeouts per nine while accumulating a 4.60 earned run mark.
