The Diamondbacks announced Monday that they’ve designated left-hander Jared Miller for assignment. His roster spot will go to infielder Wilmer Flores, whose previously reported one-year deal with the team has now been officially announced.
Miller, 25, hasn’t yet cracked the big leagues but was added to the 40-man roster last winter. At the time, he was coming off of an impressive 2017 campaign that he split nearly evenly between Double-A and Triple-A. Miller threw 70 2/3 innings of 2.93 ERA ball with 12.0 K/9 and 3.6 BB/9, seemingly setting the stage for an eventual MLB opportunity in the season to come.
Unfortunately, though he had never before exhibited such issues, Miller exhibited dramatic control problems in 2018. Through 42 Triple-A innings, he handed out 63 free passes to go with 59 strikeouts. Unsurprisingly, the results (7.71 ERA) were not pleasant. Still, it seems there’s significant raw potential remaining in Miller’s left arm.
