Red Sox and Brewers Complete Multi-Player Trade
The Boston Red Sox have acquired infielder Caleb Durbin, infielder Andruw Monasterio, catcher/infielder Anthony Seigler, and a Competitive Balance Round B draft pick from the Milwaukee Brewers. In exchange, the Brewers received left-handed pitchers Kyle Harrison and Shane Drohan, along with infielder David Hamilton.
This significant trade sees the Red Sox bolster their infield depth and future control, while the Brewers acquire promising pitching talent and an infielder to address immediate needs.
Red Sox Acquisitions
Caleb Durbin
Durbin, 25, is projected to receive everyday at-bats, with potential roles at third base or second base. He finished third in National League Rookie of the Year voting in 2025, showcasing his immediate impact.
His offensive line for the season was .256/.334/.387, featuring 11 home runs, 25 doubles, and 18 stolen bases (on 24 attempts). Notably, he maintained a walk rate of 5.9% and a low strikeout rate of 9.9%. Defensively, Durbin, a right-handed hitter with a 43.3% pull percentage, recorded 5 Defensive Runs Saved (DRS) and 2 Outs Above Average (OAA) at third base. He comes with five full seasons of club control and two minor league option years remaining.
Andruw Monasterio
Monasterio, 28, offers valuable versatility, capable of playing second base, third base, and shortstop. A right-handed hitter, he holds a career .255/.352/.375 batting line against left-handers, compared to .246/.303/.338 against right-handers. In 135 plate appearances in 2025, he recorded a .270/.319/.437 slash line with four home runs. He is controllable for four more seasons and is arbitration-eligible next offseason, providing a reliable backup option at shortstop with three minor league option years remaining.
Anthony Seigler
Seigler, 26, is anticipated to provide depth in the upper minors and could serve as a bench player. While he has batted .194/.292/.210 in 73 major league plate appearances, his performance in Triple-A this past season was impressive: a .285/.414/.478 line in 307 plate appearances, accompanied by eight home runs, 16 doubles, four triples, and 23 stolen bases (on 27 attempts). He also boasted a 16.9% walk rate and a 19.2% strikeout rate at Triple-A. Primarily used as an infielder (second base) due to challenges as a catcher, Seigler has two minor league option years remaining and at least six full seasons of club control.
Brewers Acquisitions
Kyle Harrison
Harrison, 24, is a left-handed pitcher with a promising profile. He has appeared in 42 big league games (37 starts), posting a 4.39 ERA with a 22.9% strikeout rate and an 8% walk rate. He projects as a fifth starter option for the Brewers, a team known for its history of developing pitchers. A 2020 third-round pick, Harrison was ranked as the No. 26 prospect in baseball by Baseball America prior to the 2023 season, having achieved a strikeout rate exceeding 30% in parts of two Triple-A seasons.
Shane Drohan and David Hamilton
Shane Drohan is a left-handed pitcher who adds further depth to the Brewers' pitching prospects. David Hamilton is an infielder who has primarily played second base within the Red Sox organization, with potential to play third base this spring.
Team Impact
Red Sox Infield Configuration
Durbin's arrival provides significant flexibility in the Red Sox infield, offering options for him at third base or second base. This allows for strategic placement alongside Marcelo Mayer, a former No. 4 overall pick, who could also play second or third base. Other options at second base include Romy Gonzalez, while utility player Isiah Kiner-Falefa provides backup across multiple infield positions. The additions of Durbin and Kiner-Falefa may reduce the team's immediate reliance on Mayer, who recorded a .228/.272/.402 slash line in 2025 but posted a more robust .271/.347/.471 line in Triple-A last year.
Brewers Infield Needs
The trade of their starting third baseman and two depth options creates an immediate need for infield additions for the Brewers. While shortstop Joey Ortiz and second baseman Brice Turang could potentially shift positions, the team will likely need to acquire additional infield support to fill the void. Meanwhile, the Brewers' pitching depth continues to grow substantially with the acquisition of Harrison and Drohan.
