The Boston Red Sox have expanded their roster this offseason by trading for third baseman Caleb Durbin from the Milwaukee Brewers, shaking up their lineup in advance of the 2026 MLB season. The deal, finalized on Monday, brings Durbin—along with several other assets—to Boston as the team looks to strengthen its infield options and overall depth.
This move highlights the organization’s commitment to enhancing its roster through trades rather than free-agent signings, with Caleb Durbin Red Sox trade activity marking a key part of their offseason strategy.
Details of the Six-Player Swap Between Red Sox and Brewers
The full terms of the trade include the Red Sox receiving Caleb Durbin, infielders Andruw Monasterio and Anthony Seigler, as well as a Competitive Balance B draft pick. In return, the Brewers acquire left-handed pitcher Kyle Harrison, infielder David Hamilton, and left-handed pitcher Shane Drohan.
Durbin, a 25-year-old drafted in the 14th round by the Atlanta Braves from Washington University in St. Louis, spent two years developing in the Yankees’ minor league system before joining Milwaukee in December 2024. He made his MLB debut with the Brewers last April and quickly made a strong impression.
Caleb Durbin’s Rookie Impact and Defensive Versatility
In his first major league season, Durbin appeared in 136 games, batting .256 with 11 home runs and 53 RBIs, securing third place in National League Rookie of the Year voting. Beyond his offensive contributions, he also demonstrated solid defense at third base, saving five defensive runs and showing flexibility by playing some games at second base and shortstop.

The Red Sox will benefit from this versatility as they prepare to improve a defensive infield that struggled last year.
Infield Depth and Managerial Options for Boston
Although Marcelo Mayer is projected to be Boston’s starting third baseman, Durbin’s arrival provides valuable options at both third and second base. Manager Alex Cora can also rely on recent free-agent signing Isiah Kiner-Falefa for additional infield strength, alongside established players like shortstop Trevor Story and first baseman Willson Contreras.
Improved defensive performance is a priority for the Red Sox, who led the majors in errors during the previous season. Durbin’s profile fits well with the club’s aim to tighten up its defense while maintaining a balanced offense.
Recent Trade Activity and Team Building Strategy
Caleb Durbin becomes the fourth starting-level player brought in by the Red Sox through trades this offseason, joining Willson Contreras, pitcher Sonny Gray, and pitcher Johan Oviedo. While Chief Baseball Officer Craig Breslow has been conservative in the free-agent market, he notably signed left-hander Ranger Suarez to a five-year, $130 million deal, signaling a focus on targeted investments.
As spring training approaches, the Red Sox continue to shape their roster carefully, relying on trades like this to build a competitive team for the coming season.
