BREAKING: Cubs Acquire Utility Man Willi Castro in Trade with Minnesota Twins

For the third year in a row, a ghastly lack of help off the bench has hamstrung the Cubs at certain stages of the season. This time, though, they're taking decisive action. In a deal in the final hour before the MLB trade deadline, Jed Hoyer pounced on erstwhile Twins utility infielder Willi Castro, sources confirmed to North Side Baseball. Jon Heyman was first with the news.

Castro, 28, will be a free agent at the end of this season. In the final year of his arbitration eligibility, he’s making $6.4 million this year, which means that just over $2 million remains to be paid. That’s a small price to pay, though, for a switch-hitting utility man who offers a modicum of both power and speed. After hitting a career-high 12 home runs last year, Castro already has 10 in 2025. In 344 plate appearances with Minnesota, he entered Tuesday batting .245/.335/.407.

The Twins scooped Castro up off the scrap heap before the 2023 season, signing him to a minor-league deal after he’d been non-tendered by the Detroit Tigers. Since then, he’s been the Swiss Army knife for the team, playing all over the diamond and slotted in all over the lineup card. His defense has declined sharply the last two seasons, perhaps because he’s been moved around so much, and this year, he’s mainly played second base and the corner outfield spots. However, his versatility (in both halves of innings) made him appealing to multiple teams.

For the Cubs, Castro figures to play mostly at third base, as a complement (although less than a full platoon partner) to Matt Shaw. For the first time, the Cubs will have depth not just within their lineup, but beyond it—a sense that they can bring someone in tactically within a game or give days off to their regulars, and still have competence suffuse the lineup. Castro can still move around some, positionally, and as a supplemental piece in the lineup on something less than an everyday basis, he's a dynamic addition. He's improved signifiantly this year in his performance and his under-the-hood data against left-handed pitching, and he's a beloved teammte.

A solid upgrade, Castro did come at a meaningful cost—but certainly not a painful one. The team surrendered two pitchers from their Double-A Knoxville roster, in helium guy Ryan Gallagher and righty Sam Armstrong. 

Gallagher was the club's 6th-round pick in last summer's draft, out of UC-Santa Barbara. He's made a quick ascent of the system thus far, putting up good numbers and opening some eyes with his immediate uptick in fastball velocity. He's not an electric arm, but he was a successful (if short-term) development project by the team's player development department. Even for a player who will hit free agency at season's end, he would not have been enough to headline a deal for a substantial contributor when he first entered the team's aegis. Armstrong, largely a throw-in and an organizational depth arm, is a candidate for a late switch to relief work, where he might take off a bit. There's no reason, however, for Cubs fans to lose sleep over this price.

Castro often batted near the top of the Minnesota batting order this year; much less will be asked of him in Chicago. If he can keep the line moving and occasionally spell a weary or banged-up hitter, he'll advance the team's pursuit of good playoff position nicely.
