3/10 UPDATE:
Since the first of the year, the Cubs have officially signed LHRP Matt Dermody, RHRP Kyle Johnson, RHRP Kevin McCarthy, and LHRP Eric Stout, and C-1B John Hicks to 2022 minor league contracts.
Should they be added to the MLB Reserve List (40-man roster) at some point during the 2022 season, Hicks and McCarthy are out of minor league options, and Dermody, Hicks, McCarthy, and Stout have Article XX-D rights and so they can elect free-agency if outrighted.
Johnson was an outfielder in college at Purdue and then was convertedf to RHP by the Yankees.
