Castro’s three-year run in Minnesota was one of the most pleasant surprises of the team’s recent seasons. A versatile switch-hitter who could play nearly every position on the diamond, he became a vital piece of a club that prized versatility. His time with the Cubs went poorly, but his skill set and personality left a lasting impression on Minnesota’s clubhouse. As free agency begins, it is fair to wonder whether both sides might see a reunion as mutually beneficial.

A Player the Twins Helped Rediscover

Castro’s major-league story began with the Detroit Tigers, where the young infielder found himself thrust into the big leagues at just 22 years old. Detroit was in the midst of a rebuild and needed roster fillers, rather than exercising developmental patience. The result was uneven play, as Castro posted an 87 OPS+ across parts of four seasons while struggling to find defensive consistency.

When the Twins took a chance on him before the 2023 season, it was viewed as a minor-league flier. That flier turned into one of the best under-the-radar moves of the year. Castro flourished in Minnesota, showcasing the athleticism and versatility that had intrigued scouts since his prospect days. The Tigers’ decision to non-tender him looked increasingly regrettable, as Castro blossomed into a key contributor for a playoff team.

Who is the Twins’ best pitching prospect?

Over three seasons with the Twins, Castro played 368 games and produced a .250/.335/.398 slash line, good for a 103 OPS+. His defensive flexibility was his calling card, and he even earned All-Star honors in 2024 while accumulating 4.5 WAR during his Minnesota tenure. For a player once cast aside, it was a full-circle success story.

Why the Twins Might Bring Him Back

Even after dealing him to the Cubs at the trade deadline, there is a case to be made for Minnesota re-signing Castro. He fits the Twins’ needs: a switch-hitting, athletic player who can move all over the field. His familiarity with the front office, teammates, and defensive alignments would make him a seamless clubhouse addition.

Minnesota’s roster still carries uncertainty in the middle infield and outfield, especially with recent injuries and a younger core trying to establish itself. Luke Keaschall, Royce Lewis, Matt Wallner, Austin Martin, James Outman, and Alan Roden are all promising names, but none have proved they can consistently succeed over a full season. If the Twins want someone who can step in and fill holes as needed, Castro has already shown he can handle that job.

If his market cools after a disappointing stint in Chicago, the Twins can bring Castro back on a short-term, incentive-laden deal. That type of contract would be appealing for a club working within a reduced payroll, while still seeking experienced depth.

Why the Twins Might Move On

The flip side is that Minnesota’s financial flexibility is shrinking, and even a modestly priced free agent could strain their winter plans. Castro’s late-season collapse with the Cubs (which saw him post a .485 OPS and a 42 OPS+ in 34 games) raised questions about his long-term offensive value. For a team that traded him away just months ago, bringing him back may feel like a step backward, rather than forward.

The Twins also have younger, cheaper options who need big-league opportunities. Keaschall looks ready for a larger role at second base, and Lewis is firmly entrenched at third. In the outfield, there is no shortage of competition, especially if the front office wants to see what Outman, Roden, or Martin can do over a full season.

Another complicating factor is shortstop depth. Brooks Lee is expected to start there, but the Twins need a reliable backup who can handle the position defensively. Castro has filled that role in the past, but the Twins were hesitant to use him there last year. As he approaches his age-29 season, the team might prefer to find a different veteran player more specialized at that position until Kaelen Culpepper is ready to debut later in the season.

The Verdict

A reunion between Castro and the Twins would make for a great story, but it may not be the most practical fit. His versatility and familiarity with the roster are undeniable positives, yet financial constraints and positional redundancy could steer Minnesota in another direction. If his market doesn’t develop, a low-cost deal could bring him back to a comfortable situation. Otherwise, both sides might look to start new chapters, the Twins with their emerging youth, and Castro with a chance to rediscover his spark elsewhere.

Either way, Castro’s time in Minnesota will be remembered as a rare success story—a player who revived his career and gave the Twins far more than they ever expected.
