Diamondbacks Designate Corbin Martin For Assignment

The Diamondbacks announced this morning that they’ve designated right-hander Corbin Martin for assignment. Martin’s spot on the club’s 40-man roster will go to infielder Kevin Newman, whose contract has been selected to replace injured shortstop Geraldo Perdomo on the active roster as was reported earlier this morning.

Martin, 28, was a second-round pick by the Astros in the 2017 draft and is perhaps best known as one of the prospects Arizona acquired in the Zack Greinke trade at the 2019 trade deadline alongside first baseman Seth Beer, right-hander JB Bukauskas, and infielder Josh Rojas. What appeared at the time to be a strong return for the ace righty’s services proved to be underwhelming over time, as only Rojas made an impact for the Diamondbacks at the big league level. Now all four players acquired in the Greinke deal will no longer be a part of the Dbacks organization, unless Martin clears waivers and is assigned outright to the minor leagues.

The right-hander’s time with Arizona was fraught with injuries and ineffectiveness. Martin underwent Tommy John surgery shortly before being acquired by the Diamondbacks and as a result did not make his team debut until 2021, when he struggled to a 10.69 ERA (8.42 FIP) in 16 innings of work with the big league club. Those struggles were paired with additional injuries, as Martin spent the entire second half of 2021 on the injured list in the minor leagues. 2022 was more of the same as Martin pitched to a below-average 4.84 ERA and 4.59 FIP in seven appearances for the big league club and spent the majority of the season in the minors before once again being shut down due to injury in August of that year.

Martin’s struggles in a starting role and numerous injuries led the Diamondbacks to move him to the bullpen full time during Spring Training last year in an effort to keep the right-hander healthy, but those hopes were dashed just a month later when Martin suffered a lat tendon in his right shoulder that required surgery. Martin went on to miss the entire 2023 season. He’s made just two appearances at Triple-A Reno so far in 2024 and has allowed three runs on three walks and three hits (including a home run) in three innings of work while striking out three.

Moving forward, the Diamondbacks will have one week to waive, trade, or release Martin. It’s possible the right-hander’s previous prospect pedigree could earn him the interest of another club as a potential reclamation project, though his lengthy injury history and general ineffectiveness in the majors may keep rival clubs from dedicating a roster spot to the former top-100 talent. If Martin passes through waivers unclaimed, Arizona will have the opportunity to retain him in the organization as non-roster depth going forward. As for the club, the Dbacks still have the likes of Justin Martinez and Andrew Saalfrank available as depth options on the 40-man roster behind their current bullpen mix while Paul Sewald recovers from an oblique strain.
