Nolan Arenado was back at Busch Stadium on Monday night, and this time he arrived with the Arizona Diamondbacks to face the St. Louis Cardinals. The visit reopened one of the most personal chapters in recent Cardinals history: the trade that brought him to St. Louis on February 1, 2021, and the commitment he made soon after to stay.
The Cardinals acquired Arenado and $51 million in cash considerations in exchange for Austin Gomber, Elehuris Montero, Tony Locey, Mateo Gil and Jake Sommers, then heard him say he had no interest in using his opt-out option. He also said he had always admired the Cardinals and wanted to end his career in St. Louis, a promise that gave the deal a rare kind of certainty in a sport built on escape clauses.
That certainty lasted through another turning point after the 2022 season, when the Cardinals gave him an additional opt-out option and Arenado said in late October of 2022 that he would not opt out of his St. Louis Cardinals contract. He finished third in the MVP vote that year, but the final two seasons in St. Louis were also marked by nagging injuries and a drop in offensive production. The contrast matters because his return now is not just about where he once played, but about what changed between the pledge and the departure.
For St. Louis, Arenado’s return is being welcomed with the memory of a player who wanted to be a Cardinal and said he would keep his word as long as the organization wanted him. For Arenado, the trip back is loaded with that history, and Monday night put it in front of the same fans who once thought they might watch him finish his career there.
What comes next is simpler and less sentimental: the series at Busch Stadium continues, with Arenado now facing the club he once said he hoped to call home for the rest of his career.
