Diamondbacks designate reliever for assignment 

The D-Backs announced this afternoon they’ve designated reliever Peter Solomon for assignment. The move clears a spot on the 40-man roster for outfield prospect Kristian Robinson, who has been officially reinstated from the restricted list and optioned to Low-A Visalia.

Robinson has been on the restricted list for the better part of three years. A high-profile amateur signee out of the Bahamas, he quickly became one of the sport’s most promising low minors talents. Robinson appeared among Baseball America’s top 100 prospects entering both the 2020 and 2021 seasons and was regarded as a potential franchise building block.

His career has been in limbo for the past few years for legal reasons. Robinson pled guilty to what was initially a felony assault charge stemming from an April 2020 incident with a law enforcement officer. (Zach Buchanan of the Athletic wrote in 2021 that Robinson said he’d been amidst a mental health crisis at the time.) As part of the plea agreement, Robinson’s charge was to be reduced to a misdemeanor if he successfully completed 18 months of probation without incident. In the interim, having a felony on his record prevented him from renewing a work visa that would allow him to continue to participate in minor league games. Robinson had been permitted to partake in extended Spring Training workouts but could not play in official games.

Nevertheless, he would’ve been eligible for selection in the Rule 5 draft over the 2021-22 offseason. The D-Backs added him to their 40-man roster in a procedural move to keep him out of that process but immediately placed him back on the restricted list, temporarily clearing that spot. Robinson fulfilled his probation requirements this spring; as a result, his conviction was reduced to a misdemeanor and he was granted his work visa at the end of April. That opened a 30-day rehab window before which the Diamondbacks had to decide whether to activate him onto the 40-man roster or make him available to other clubs via DFA.

They’ll go with the former course of action to ensure Robinson remains in the organization. He hasn’t played any minor league games over the past month — Nick Piecoro of the Arizona Republic reported a few weeks back that he’s been bothered by a minor hamstring injury — but he’s now in position to get back into game action once healthy. Robinson still hasn’t advanced past Low-A and surely won’t be under consideration for a major league look in 2023.

Solomon, 26, landed with Arizona over the offseason in the Triple-A phase of the Rule 5 draft. His MLB experience at the time consisted of six outings for the 2021 Astros. Solomon eventually bounced to the Pirates via waivers before clearing waivers at the end of last year. The D-Backs selected his contract in April and have used him five times in a multi-inning relief capacity.

The righty has been hit hard over his 13 1/3 frames for the Snakes. He’s surrendered 18 runs on 17 hits and 11 walks while striking out six. Solomon has also allowed 15 runs in 13 innings with Triple-A Reno, struggling with home runs in one of the game’s toughest home ballparks for pitchers. He’s likely to land on waivers within the next week.
