Red Sox Acquire Caleb Durbin for Kyle Harrison and Two Others in Brewers Trade

The Boston Red Sox have acquired 25-year-old third baseman Caleb Durbin from the Milwaukee Brewers in exchange for a three-player package headlined by Kyle Harrison.

The Boston Red Sox have finalized a Caleb Durbin trade with the Milwaukee Brewers to secure a new starting third baseman. According to sources cited by ESPN's Jeff Passan on Monday, the 25-year-old infielder moves to Boston following a 2025 rookie campaign where he posted a .256 batting average. During that season, Durbin recorded 11 home runs, 53 RBIs, and successfully converted 18 stolen base attempts. This transaction addresses a critical roster vacancy created by the departure of Alex Bregman through free agency.

To facilitate the acquisition of Durbin, the Red Sox are sending a three-player package to Milwaukee. The deal is headlined by 24-year-old left-handed pitcher Kyle Harrison. Last season, Harrison split time between Boston and San Francisco, accumulating 35 2/3 innings on the mound. During that span, the southpaw maintained a 4.04 ERA and struck out 38 batters. Joining Harrison in the move to the Brewers organization are infielder David Hamilton and left-hander Shane Drohan.

Impact on the Red Sox Infield Depth

Before the Caleb Durbin trade, the Red Sox were projected to start prospect Marcelo Mayer at third base. Mayer, while highly heralded, has faced a career path frequently interrupted by various injuries. By bringing in Durbin, Boston gains a player with proven major league production from the previous year. Durbin’s ability to provide power and speed—evidenced by his double-digit home runs and nearly 20 steals—offers a different dynamic to the hot corner than the previous incumbent.

David Hamilton leaves Boston after three seasons with the club. Primarily utilized as a second baseman, Hamilton appeared in 91 games during his final stint with the Red Sox. His offensive output included a .198 batting average, six home runs, and 19 RBIs. His departure, alongside Drohan, clears space for Durbin to take over the everyday duties at the third base position.

Pitching Assets Heading to Milwaukee

The Brewers' side of the Caleb Durbin trade focuses heavily on left-handed pitching depth. Kyle Harrison brings a strikeout rate of over one batter per inning, based on his 38 punchouts in 35 2/3 frames. This efficiency was a hallmark of his performance across two different National and American League clubs last year. Shane Drohan adds a second left-handed arm to the Milwaukee return, though he was part of a package that also included a veteran middle infielder.

Roster Adjustments and Future Outlook

This move signals a shift in Boston’s strategy following the loss of Alex Bregman. Rather than relying solely on the health of Marcelo Mayer, the front office opted for Durbin’s 53-RBI production profile. The trade effectively resets the left side of the Red Sox infield while providing the Brewers with three younger assets to integrate into their system. With Harrison’s 4.04 ERA now in the Milwaukee rotation or bullpen mix, both teams have addressed specific positional needs through this four-player swap.
