When it comes to first base, Anthony Rizzo has the position locked down through 2021, at which point he will be just 32 years old. That’s three more years with the man who is the heart of the lineup and the team. As for his backups, the Cubs could use Kris Bryant, Ben Zobrist, or Victor Caratini. And considering Rizzo has played at least 153 games the last four years and five of the last six, the Cubs don’t have a great need for a replacement.
First base has never been a position of strength in the minors lately, basically because of Rizzo, and the Cubs rarely draft for the position.
