The St. Louis Cardinals have their starting infield locked down after the acquisition of Nolan Arenado. This also means that Matt Carpenter will likely be the primary bench bat. However, Carpenter cannot play shortstop, and he has not played second base since 2018 when he played just 83 below average innings there. This means that the Cardinals will need a utility infielder who can play up the middle this season, in order to give days off to Paul DeJong and Tommy Edman. Additionally, it would also be beneficial if that player could play the corners as well in order to give Mike Shildt more flexibility.
