The Boston Red Sox have completed a trade with the Milwaukee Brewers, acquiring infielder Caleb Durbin along with two other depth players to bolster their remaining infield roster spots. This move, aimed at addressing Boston’s infield needs, adds a young player with notable major league experience in Durbin. The Brewers received three less-established prospects in exchange, in a deal first reported by ESPN’s Jeff Passan and further detailed by The Athletic’s Will Sammon.
Caleb Durbin, a 25-year-old who primarily plays third and second base, is coming off a solid rookie campaign where his ability to get on base and defensive versatility stood out. Over 506 plate appearances, Durbin produced a .256 batting average with an on-base percentage of .334, hitting 11 home runs and stealing 18 bases. His 2.8 bWAR and 2.6 fWAR earned him third place in the National League Rookie of the Year voting.
Durbin’s path to the majors is uncommon; he was a 14th-round pick in 2021 out of Washington University in St. Louis, a Division III program. After being briefly traded by the Braves to the Yankees in late 2022, he then moved to the Brewers in a trade involving reliever Devin Williams. Durbin has since established himself as a versatile infielder capable of playing second base, third base, and emergency shortstop. Standing 5-foot-7, his offensive strength comes from his tiny strike zone, exceptional plate discipline, and bat control, making him tough to strike out. He typically pulls the ball, which could make Fenway Park’s Green Monster an advantageous environment for his hitting style.
The Red Sox’s plans for Durbin are still unfolding, with multiple defensive configurations possible. With Marcelo Mayer also available and Trevor Story secured at shortstop, Durbin might take over second base duties or even replace Alex Bregman at third, perhaps encouraging Mayer to shift primarily to second base.
Additional Players Sent to Boston
Alongside Durbin, the Red Sox acquired Anthony Seigler, a 26-year-old versatile infielder and outfielder. Seigler, once a first-round draft pick by the Yankees in 2018 as a catcher, struggled to advance beyond the upper minors before signing with Milwaukee as a minor league free agent. His time with the Brewers revealed his ability to cover multiple positions and contribute at the plate with patient at-bats, though his offensive production in the majors remains limited. In 34 games last season, Seigler hit .194 with a .292 on-base percentage, offering more value as depth likely to shuttle between Boston and its Triple-A affiliate in Worcester.
The trade also includes 28-year-old Andruw Monasterio, a catcher and infielder hailing from Venezuela, who has been a valuable minor league free agent acquisition for Milwaukee. After traveling through several organizations, Monasterio made his MLB debut with the Brewers in 2023 and had his best major league season in 2025, hitting .270/.319/.437 over 68 games. Known for a strong pull-oriented right-handed swing, Monasterio can cover multiple infield positions and has even played first base and left field despite defensive limitations from his average arm strength. With two minor league options remaining, he is expected to compete for a bench role with the Red Sox, likely sharing time in Worcester with Seigler.
The deal also transfers a compensatory balance pick, Round B, 67th overall, to Boston. This pick carries a significant bonus pool allocation, exceeding $1.28 million last year, which increases this year. It will offer the Red Sox more financial flexibility in the upcoming draft, supplementing their first-round selection at 20th overall.
Milwaukee Brewers Acquire Young Pitching and Utility Depth
In return, the Milwaukee Brewers received three players from Boston, primarily adding youth and pitching depth as they continue to nurture promising talent. Among them is left-handed pitcher Kyle Harrison, 24, who was once one of the San Francisco Giants’ top prospects. Harrison, acquired by the Red Sox in the Rafael Devers trade, spent most of 2025 in Triple-A but made 35.2 major league innings with a 4.04 ERA. Concerns about his inconsistent command remain, but he features a mid-90s fastball with notable arm-side run and extension. Milwaukee aims to harness his potential, following a trend of extracting value from previously heralded pitching prospects such as Quinn Priester, who found success after a prior trade from Boston.
David Hamilton, a 28-year-old shortstop and utility infielder drafted by Milwaukee in 2019, also joins the Brewers. Hamilton sheds light on the importance of versatile bench players, capable of covering multiple infield positions and providing speed on the bases. Though his offensive numbers are modest, with a declining batting average over recent seasons, Hamilton’s defensive range and base-stealing prowess—57 steals in 68 career attempts—make him a useful piece. His flexibility allows him to play shortstop, second, and third base effectively.
The third player heading to Milwaukee is 27-year-old left-handed pitcher Shane Drohan, ranked 15th on the Red Sox’s top prospects list. Drafted from Florida State in 2020, Drohan’s career has taken a convoluted path with injury setbacks, including nerve decompression surgery after being selected in the 2024 Rule 5 draft by the White Sox and then returned to Boston. Despite forearm irritation in 2025, he made a strong late-season comeback. Drohan features a four-pitch arsenal including a mid-90s fastball, slider, curveball, and changeup, and has added a cutter to his repertoire. Projected as a multi-inning reliever or spot starter, he offers the Brewers a valuable arm, although durability remains a concern given a limited workload over recent seasons.
Implications and Future Outlook for Both Teams
This trade signals the Red Sox’s urgency to finalize their infield makeup with a blend of youth and multi-positional flexibility as the 2026 season approaches. Caleb Durbin’s arrival could spark significant adjustments in Boston’s defensive alignments, particularly regarding Marcelo Mayer and Trevor Story’s roles. The addition of Seigler and Monasterio enhances organizational depth but likely positions these players for more time in Triple-A than on the major league roster.
For the Brewers, acquiring Harrison, Hamilton, and Drohan fits their model of capitalizing on promising but underutilized players. Harrison’s potential to stabilize the rotation or bullpen and Drohan’s versatility could be pivotal as Milwaukee looks to rebuild or reinforce pitching depth. Meanwhile, Hamilton’s speed and defensive skills fill necessary roles, even if his bat limits everyday play.
The inclusion of the compensatory pick gives the Red Sox crucial draft capital, enabling them to remain competitive in developing homegrown talent. Overall, the trade reflects both teams’ contrasting needs and the ongoing balancing act between immediate major league readiness and long-term projection. Fans of both clubs will be watching closely to see how these new acquisitions adjust and contribute as Spring Training nears.
