During Spring Training before the 2017 season, and the final guaranteed year on Molina's contract, the Cardinals began to negotiate an extension to keep Molina in St. Louis for the remainder of his career. He agreed to a three-year contract extension for a reported $60 million, making him the highest-paid catcher in baseball. He was not interested in exercising his 2018 mutual option, which would have been worth $15 million. The extension assured Molina of remaining in St. Louis through 2020, and increases the chances that he will finish his career having played for just one organization, the one that drafted him. This distinction of having Molina retire as a Cardinal is something that carried weight for both parties throughout the negotiations.
