12/1 UPDATE: The Cubs have tendered 2018 contracts to 27 of the 29 unsigned players on their MLB reserve list (40-man roster).
RHRP Hector Rondon and C-1B-3B Taylor Davis were non-tendered and are now unrestricted free-agents, free to sign a 2018 major league or minor league contract with any club (including the Cubs).
Rondon could not be tendered a 2018 contract with a salary less than $4.64M (and that's with the maximum 20% cut from his 2017 salary), but he was likely to get somewhere north of $6M if he had taken the Cubs to an arbitration hearing, and the Cubs obviously weren't interested in going there. Now that he has been non-tendered, Rondon's 2018 salary is no longer restricted by the maximum 20% cut rule, so the Cubs (or any other club) could sign him for any amount (but no less than the MLB minimum salary if it's a major league contract).
It's very possible that the Cubs will try and re-sign T. Davis to a minor league contract (for MLB "split contract money" and an NRI to Spring Training), preferably after the MLB Rule 5 Draft a week from Thursday. Because T. Davis was an MLB Rule 6 Draft Excluded Player, he could not be sent outright to the minors during the off-season.
So the Cubs MLB reserve list now stands at 34 (six slots are open).
