Diamondbacks designate struggling reliever Stefan Crichton for assignment

The Diamondbacks announced Wednesday that they designated right-handed reliever Stefan Crichton for assignment and recalled outfielder Nick Heath from Triple-A Reno in his place.

Crichton, 29, worked some high-leverage spots for the Snakes early in the season and even tallied four saves in the first five weeks. His results have tanked as of late, however, leading to Wednesday’s decision. Over his past 15 appearances, Crichton has totaled only 11 innings of work, during which time he’s been tagged 10 runs on 16 hits (two homers) with more walks (six) than strikeouts (five).

From 2019-20, Crichton was a solid member of the D-backs’ relief corps, tallying 56 1/3 innings of 3.04 ERA ball with a 50.3 percent grounder rate, a 24.1 percent strikeout rate and a 7.3 percent walk rate. His velocity, strikeout rate and walk rate have all gone in the wrong direction for two consecutive seasons, however. This year’s middling 13.9 percent clip is barely half what it was back in 2019 when he notched a career-best 26.8 percent mark.

The Diamondbacks will have a week to trade Crichton or attempt to pass him through outright waivers. This year’s struggles and velocity dip, paired with the fact that he’s out of minor league options, might temper optimism among other clubs, however.
