The St. Louis Cardinals entered the 2025 season knowing it'd be a transition year. While a lot of the long-term pieces are still on the team, there's been some turnover in the short term already.
Now that the 2025 season is over for St. Louis, after going 78-84, missing the playoffs by five games, the Cardinals have a lot of work to do this offseason. But it won't be done by John Mozeliak, as he's stepping down.
On the same day that the MLB postseason begins, the Cardinals officially announced that Chaim Bloom is taking over as the president of baseball operations for the Cardinals, with Mozeliak stepping away from his longtime role in St. Louis.

This was an expected move for the Cardinals, as the transition from Mozeliak to Bloom has been a long time coming. While it's the move that everyone knew was on the horizon, the official announcement is still a huge deal.

Bloom taking over as the president of baseball operations officially begins a new era of Cardinals baseball. After years with Mozeliak at the helm, the Cardinals are letting Bloom take over, and some major changes are expected to come to St. Louis this offseason.
While there will be a lot of new faces on the team next season, the Cardinals might have more than normal, as they're planning on cutting ties with a lot of their veteran players.
Nolan Arenado and Sonny Gray, despite no-trade clauses, are both expected to be dealt this offseason. A trade won't be easy, but the Cardinals' clear intentions to rebuild have been conveyed, and both have expressed their openness to a deal.

Willson Contreras could also be on the move, though he hasn't been nearly as open to a move as Arendo and Gray have. Aside from those three veterans, Lars Nootbaar and Brendan Donovan are two other names to watch in the trade market this winter.
It'll likely take a few years for Bloom to construct his ideal roster, and a lot of the veterans are likely to find new homes as Bloom retools the roster over the next few years.
After all of the success St. Louis has had in recent years, this rebuild will be a tough one to sit through. However, it's a necessary one to find long-term success, as the team needs a major overhaul to contend going forward.
Bloom is officially the new president of baseball operations in St. Louis, meaning a new era is officially underway, with plenty of changes expected in the coming months ahead of the 2026 MLB season.
