The 2025 MLB season became a prove-it year for the St. Louis Cardinals' young core. With much uncertainty of roster capability due to development issues, roster patching, and lack of resources provided by the front office, John Mozeliak exited on the precipice of seeing what the roster he constructed was capable of.

Alec Burleson also proved he is no longer to be considered as a platoon player, as he won the Silver Slugger Award in a utility role.
