The Boston Red Sox continue to take firm steps in building a team with real title aspirations in the 2026 season. This Sunday, the organization made a high-impact move by acquiring first baseman Willson Contreras in a trade with the St. Louis Cardinals, according to information reported by Jeff Passan of ESPN and later confirmed by MLB.com.

According to reports, Boston will send right-handed pitcher Hunter Dobbins, along with fellow pitchers Yhoiker Fajardo and Blake Aita, to the St. Louis organization. The Red Sox will also receive $8 million as part of the deal. The trade required Contreras to waive a no-trade clause in his contract, which is still in effect.

Contreras, 33, is in the third year of a five-year, $87.5 million contract signed before the 2023 season. His remaining salary for 2026 is $18 million, which Boston will pay as part of its effort to bolster the heart of its lineup.

Contreras' Fit ??and Recent Trajectory

The arrival of Willson Contreras gives the Red Sox a key piece at first base and a proven hitter in the major leagues. In 2025, the Venezuelan surprised everyone with his defensive adaptation to first base, a position to which the Cardinals moved him to keep him healthy and in the lineup. His performance was remarkable: he finished tied for fourth in all of MLB in Outs Above Average (plus-6) among first basemen. Although St. Louis originally signed him to be Yadier Molina's successor as catcher, his time with the Cardinals was marked by adjustments. During his first few seasons, the team had reservations about his pitching skills and opted to use him frequently as a designated hitter. When he began to show defensive improvement behind the plate in 2024, a fracture in his left forearm, caused by an accidental hit from J.D. Martinez's bat, sidelined him for six weeks. Despite these setbacks, Contreras was a consistent and feared presence at the plate.In the 2025 season, he hit 20 home runs and set a personal best with 31 doubles. In his three seasons with St. Louis, he posted a .261/.338/.459/.817 slash line with 55 home runs and 183 RBIs. From Boston's perspective, the move also has a strategic component. This is the second trade that the Cardinals' new president of baseball operations, Chaim Bloom, has made with his former team. Last month, St. Louis sent pitcher Sonny Gray to the Red Sox, reinforcing a business relationship that is becoming increasingly common between the two franchises.
