Cardinals are actively considering moving Arenado this offseason as part of their rebuild plan. While he remains under a large contract, the organization has signaled openness to trading him to clear payroll and give opportunities to younger players.
One of the most frequently mentioned destinations is the Boston Red Sox of the American League East. Boston has a need at third base and may pivot to Arenado if their preferred target doesn’t become available.
The Cardinals appear willing to absorb part of Arenado’s remaining salary to make a deal more feasible for a contending club. However, there are strong headwinds: Arenado’s offensive production has dipped, and his contract plus full no-trade clause make the market more limited.
From Boston’s perspective, acquiring Arenado would fill a veteran need, but it comes with both performance and long-term financial risks. Analysts note that the return the Cardinals could command may not be very high given his current profile.
In short: the Cardinals are linked to a potential trade of their eight-time All-Star to an AL East club, primarily Boston, but nothing is finalized yet and there are notable obstacles.
