The Astros have released right-hander Dylan Coleman after designating him for assignment last week, as indicated on the team’s transaction log at MLB.com. He’s now a free agent.
Coleman, 28 next month, was acquired from the Royals in a small December swap and has spent the bulk of the season in Triple-A Sugar Land. He pitched one scoreless big league frame for Houston back on April 3 but has limped to a more problematic 6.50 earned run average in 36 Triple-A frames. He’s been on a particularly rocky run of late, yielding 12 runs (11 earned) on eight hits and nine walks over his past 5 2/3 innings. That recent slide surely played into the decision to designate the former fourth-rounder (Padres, 2018) for assignment.
As recently as 2022, Coleman looked well on his way to establishing himself in the Royals’ big league bullpen. He made his MLB debut late in the 2021 season and in 2022 piled up 68 innings of work. In a total of 74 1/3 innings from ’21-’22, he notched a very sharp 2.66 ERA while fanning 24.8% of his opponents. His 12.1% walk rate was in need of improvement, but Coleman sat 97.7 mph with his heater, picked up swinging strikes at an impressive 13% clip, avoided hard contact (86.4 mph average exit velocity, 6.3% barrel rate, 35.9% hard-hit rate) and did a good job keeping the ball in the yard (0.61 HR/9).
That success deteriorated quickly in 2023, however. Coleman was rocked for an 8.84 ERA in 18 1/3 big league innings and walked 19 batters in that time. The command troubles continued in Triple-A Omaha, where he issued a free pass to a calamitous 21.8% of his opponents. The right-hander’s average fastball also plummeted from the prior season’s 97.5 mph to 95.2 mph in the majors (and 96.1 mph down the stretch in Triple-A).
All of those problems have persisted, if not worsened, following the change of scenery. Coleman walked 23.9% of his opponents with Sugar Land in the Astros organization, and Statcast measured his average heater in Triple-A this season at 95.7 mph — well shy of his 2021-22 levels. Whatever the reason for the downturn in command and velocity, the 2023-24 version of Coleman looks like a decidedly different pitcher than the reliever who showed quite a bit of promise from 2021-22.
Coleman’s prior track record, minimal acquisition cost — he’ll very likely require only a minor league deal to sign — and remaining club control (under two years of MLB service) should be enough to spark interest from a new club, whether that’s in the coming days/weeks or in the offseason.
