Holton was designated for assignment by the Diamondbacks on Wednesday.
As a result of the team officially signing Andrew Chafin, Holton was removed from the 40-man roster. The left-hander will now either get claimed by another team, be released outright or remain with Triple-A Reno, the last of which seems the most likely. Overall, Holton appeared in 10 games with the Diamondbacks in 2022, allowing three runs over nine innings while recording six strikeouts.
