The Cubs announced Monday that they’ve designated right-hander Michael Arias for assignment. His spot on the 40-man roster will go to fellow right-hander Colin Rea, whose previously reported one-year deal is now official.
Arias, 23, was selected to Chicago’s 40-man roster in the 2023-24 offseason in order to protect him from the Rule 5 draft. The infielder-turned-reliever spent the 2024 season in the upper minors, pitching to a combined 4.77 ERA in 60 innings between Double-A and Triple-A. Arias was more effective at the former than the latter, logging a 3.75 ERA in Double-A but a 5.35 mark in Triple-A.
Command was an issue for Arias at both levels, as has been the case since he moved to the mound. The hard-throwing righty sits mid-90s with his sinker but has walked a dismal 16.5% of opponents in his professional career — including 19.6% of his opponents in 36 1/3 Triple-A frames this past season.
Even with that notable flaw, Arias still landed 11th on FanGraphs’ recent ranking of the Cubs’ farm system. Eric Longenhagen and Travis Ice profiled the righty, touting a potential plus-plus changeup, a bat-missing slider and the ability to work multiple innings in relief. Arias’ location struggles — FanGraphs’ report notes that Arias “hasn’t even progressed to 40-grade control” yet — are prominent enough that the Cubs are comfortable trading him or exposing him to waivers.
While the Cubs may feel they don’t have room for him on their 40-man, Arias is a 23-year-old with a sinker up to 98 mph, a pair of average or better secondaries, and two minor league option years remaining. He seems like he’ll draw interest from another club, be it via a small trade or simply via waivers. The Cubs have five days to trade Arias. After that, he’ll need to be placed on waivers (a 48-hour process).
