Red Sox Acquire Willson Contreras

The Red Sox have acquired first baseman Willson Contreras from the Cardinals for right-hander Hunter Dobbins and multiple minor league pitchers, ESPN’s Jeff Passan reports (multiple links).  Right-handers Yhoiker Fajardo and Blake Aita are the prospects in question, as per The Athletic’s Ken Rosenthal.  ESPN’s Jesse Rogers reports that Contreras will get a $1MM bonus as a sweetener for waiving his no-trade clause.

MassLive.com’s Chris Cotillo writes that the Cardinals will be including $8MM to help cover part of the $41.5MM still owed to Contreras over the remainder of his contract.  Contreras is owed $18MM in 2026, $18.5MM in 2027, and the Red Sox hold a $20MM club option on his services in 2028, with a $7.5MM buyout.  The club option was also adjusted as part of the trade, The Athletic’s Katie Woo reports, as Contreras was previously slated for a $17.5MM club option with a $5MM buyout.  All in all, Contreras is owed $44MM in guaranteed money over the remainder of his deal, and that drops to a $36MM commitment for the Red Sox when factoring in the Cardinals’ $8MM contribution.

Less than a month after landing Sonny Gray, the Sox have now acquired another prominent veteran talent from St. Louis.  Contreras and Gray both had full no-trade clauses in their contracts, and neither player was open to waiving that protection last winter when the Cardinals were first exploring a rebuild.  After a lackluster 78-84 season sent the Cards more firmly looking towards the future, Gray, Contreras, and Nolan Arenado (who blocked a deal to the Astros last winter) all indicated in recent months that they were more open to accepting a trade.

In Contreras’ case, he cracked the door open at the end of season by saying that “if something comes up…and it makes sense for me and my future, how about we talk about that?” Contreras said.  The first baseman stressed that he was still eager to contribute as a veteran leader within the Cardinals’ rebuild, though reports emerged a few weeks ago that Contreras was showing an increased willingness to waive his no-trade clause and move on to a new challenge.

Contreras (who turns 34 in May) ends his St. Louis tenure with a .261/.358/.459 slash line and 55 home runs over 1416 plate appearances from 2023-25.  Signed to a five-year, $87.5MM free agent deal back in December 2022, the idea was that Contreras would take over from Yadier Molina as the team’s regular catcher, yet in somewhat awkward fashion, the Cardinals reduced Contreras’ playing time behind the plate and used him regularly as a DH.

Heading into the 2025 season, Contreras became a full-time first baseman, returning to a position he’d played only a handful of times earlier in his career with the Cubs.  The Outs Above Average metric gave Contreras a positive +6 grade for his first base work in 2025, but he also received -1 Defensive Runs Saved.  Regardless, it would seem like Contreras is at least a passable defender at the cold corner, and the Red Sox can live with only so-so defense as long as the former All-Star continues to hit.  Contreras is a right-handed batter, which helping balance out a Boston lineup that tilts to the left side.

Contreras’ final four seasons in Chicago overlapped with Craig Breslow’s time working in the Cubs’ front office, before Breslow was hired to take over Boston’s baseball operations department following the 2023 season.  Breslow’s tenure has thus far been defined by significant trades, ranging from the deals that brought Gray, Garret Crochet, and now Contreras to Fenway Park, and last June’s surprising move that sent Rafael Devers to the Giants.

One of the many factors involved in the Devers trade was Devers’ displeasure over being asked to move to first base in the wake of Triston Casas’ season-ending knee surgery in early May.  While Romy Gonzalez and deadline pickup Nathaniel Lowe helped fill the first base void, there was little doubt the Sox were going to address the position in a larger fashion this winter.  Pete Alonso, Isaac Paredes, Kazuma Okamoto, Munetaka Murakami, and Bryce Eldridge were among the first base candidates on Boston’s radar on the free agent and trade fronts this winter, and Cotillo reported last week that Contreras was another name under consideration.

With Contreras now in the fold, a Casas trade now looks increasingly likely.  Casas has been floated in trade talks even dating back to last winter and prior to his knee surgery, and despite his injury-shortened season, rival clubs figure to have interest in the former top prospects.  Conversely, if the Sox could figure out a way to dump Masataka Yoshida’s contract, Casas could share first base/DH duties with Contreras.

Adding a first baseman solves another piece of Boston’s infield puzzle.  Contreras is now at first base and Trevor Story will be at shortstop, with top prospect Marcelo Mayer in line to see action at second or third base.  The Red Sox remain linked to such other major infield names as Bo Bichette or old friend Alex Bregman, and Contreras’ $36MM price tag shouldn’t prevent the Sox from spending big on either of those names, even considering Boston’s recent wariness about major financial commitments.  Trading an outfielder could further shake up the position-player mix, and there have been consistent rumors about the possibility of the Sox moving an outfielder for pitching.

The Red Sox entered the winter with a lot of pitching depth in terms of young arms, yet were lacking proven frontline hurlers that could join Crochet and Brayan Bello in the rotation.  Gray was one answer, and fellow trade pickup Johan Oviedo could be another after Oviedo was acquired from the Pirates.  This has made Breslow more comfortable in trading from further down his pitching depth chart, and after moving Richard Fitts and prospect Brandon Clarke to St. Louis for Gray, Breslow has now parted ways with Dobbins, Fajardo, and Aida.
