The Cardinals and their catcher are finalizing a one-year deal Monday night for the coming season, two sources confirmed.
Molina, 38, and the Cardinals both felt they were close to an agreement before Molina went to the Caribbean Series to compete for Puerto Rico's representative team. The championship was Saturday, and Molina's return home spurred the final stages of his return to the Cardinals.
It will be Molina's 18th season with the only club that he's known.
This is a breaking news story and will be updated.
