FORT MYERS, Florida.– The Boston Red Sox continued their infield restructuring this Monday, on the eve of the official start of Spring Training, by acquiring infielder Caleb Durbin, a finalist for the 2025 National League Rookie of the Year award, in a six-player trade with the Milwaukee Brewers.

Change Details

Red Sox receive:

• INF Caleb Durbin
• INF Andruw Monasterio
• INF Anthony Seigler
• 2026 Draft Selection (Competitive Balance Round B)

Brewers receive:

• LZ Kyle Harrison
• INF David Hamilton
• LZ prospect Shane Drohan

Durbin, 25 years old, recorded an offensive line of .256/.334/.387 last season, mainly alternating between third base, shortstop, and second base, which fits with Boston’s bet on defensive versatility for the 2026 season. With shortstop Trevor Story and Venezuelan first baseman Willson Contreras projected in fixed roles, the second and third base positions are shaping up as areas of rotation. In that scenario, Durbin joins a group that includes Marcelo Mayer, Isiah Kiner-Falefa (pending physical exam), and Romy González, all capable of playing multiple infield positions. Despite his light build (1.70 meters), Durbin had a notable impact on the Brewers, champions of the National League Central Division in 2025. In 445 at-bats, he hit 11 home runs, 25 doubles, stole 18 bases and accumulated a bWAR of 2.8, standing out for his control of the strike zone and his offensive consistency. The main piece sent to Milwaukee is the left-handed Kyle Harrison, a former high-profile prospect who arrived in Boston in the trade involving Rafael Devers last June. However, the depth of young starters with contractual control left Harrison without a clear spot on the Opening Day roster. Since his debut in 2023, the pitcher has an ERA of 4.39 in 42 appearances, 37 as a starter. Venezuelan Andruw Monasterio, 28 years old, adds additional depth to Boston’s infield. In 2025, he played in 68 games with Milwaukee, batting .270, with nine doubles, four home runs, and 16 RBIs, in addition to playing multiple infield positions and occasionally in the outfield. In Triple-A Nashville, he recorded a batting average of .250 and an on-base percentage of .346. For his part, Anthony Seigler, 26 years old, arrives as an organizational depth option. In his first season in the Major Leagues, he participated in 34 games with the Brewers. The left-handed hitter and ambidextrous pitcher was originally selected by the New York Yankees in the first round of the 2018 Draft. With this move, the Red Sox continue to strengthen their roster with a view to a 2026 season in which the flexibility and depth of the infield will be key.
