3/21 UPDATE:
The Cubs have signed second contract free-agent RHP Vince Reilly (ex-OAK) to a 2024 minor league contract.
3/1 UPDATE:
The Cubs have signed 1B-OF Garrett Cooper to a 2024 minor league contract.
Cooper was a post-2023 MLB Article XX-B free agent. If an Article XX-B MLB free-agent signs a minor league contract at least ten days prior to MLB Opening Day, and then is not selected to an MLB Reserve List (40-man roster) or MLB 60-day Injured List by 12 PM (Eastern) on the 4th day prior to MLB Opening Day, the player can unilaterally opt-out of the minor league contract immediately, or on May 1st if he has not been added to an MLB Active List (26-man roster) or MLB 60-day IL by that date, or on June 1st if he has not been added to an MLB Active List (26-man roster) or MLB IL by that date.
