Cubs designated RHP Michael Arias for assignment.
The Cubs needed a spot on the 40-man roster for Colin Rea, who they signed over the weekend, so Arias was let go. The 23-year-old has yet to make his MLB debut and spent most of 2024 in Triple-A, where he had a 2.09 WHIP in 36.1 innings. Including his 24 innings at Double-A in 2024, Arias posted a 4.77 ERA and 1.86 WHIP but 72 strikeouts in 60 1/3 innings. His raw stuff is solid, and he has a career 4.25 ERA in 97 minor-league appearances (32 starts), so a few teams, including the Cubs, will likely be looking to sign him to a minor-league deal once he clears waivers.
