The D-backs announced Wednesday that they’ve designated lefty Tyler Holton for assignment in order to open a spot on the roster for fellow southpaw Andrew Chafin, whose one-year deal to return to Arizona has now become official.
Holton, 26, made his big league debut with the Snakes in 2022, yielding three runs on eight hits and a pair of walks with six strikeouts in nine innings of work. The 2018 ninth-rounder spent the remainder of the season in Triple-A Reno, where he worked to a 4.43 ERA with a 23.5% strikeout rate against a 9.3% walk rate in 44 2/3 innings (22 relief appearances, two starts).
The 2022 season as a whole represented a sizable turnaround for Holton, who split the 2021 campaign between Double-A and Triple-A, combining for a 6.72 ERA in that time. There was some promise under the hood even amid those ugly bottom-line results, however, as Holton fanned 26.5% of his opponents against a solid 6.5% walk rate.
Holton has regularly posted strong strikeout and walk rates and a solid 45.2% ground-ball rate in parts of three minor league seasons. He’s also generally avoided the long ball, even when pitching in hitter-friendly settings like Reno. Since he was just selected to the MLB roster last year, he has a pair of minor league options remaining. All of that could hold appeal to other clubs either on waivers or via a small trade, but Holton has never been considered among the D-backs’ very best prospects and doesn’t have the type of power arsenal teams so frequently covet, averaging just 90.5 mph on his heater in this past season’s brief MLB debut.
The D-backs will have a week to trade Holton, attempt to pass him through outright waivers or release him.
