If you think the young guys could be regulars in the future, then you don't use them as backups next year. They either start in the MLB, or in AAA.
I really, REALLY don't want to see Zeke next year. Maybe sign Saunders cheap to be the backup / platoon, since Teoscar could probably handle CF if Pillar was to go down. Also, if we're not gonna play Pearce at all at 2nd when needed, then trade him. Part of his value is in the lineup flexibility.
