In a surprising turn of events, the Milwaukee Brewers have executed a trade with the Boston Red Sox, sending third baseman Caleb Durbin along with utility infielders Andruw Monasterio and Anthony Seigler, as well as their competitive balance B pick. In exchange, the Brewers have acquired left-handed pitcher Kyle Harrison, infielder David Hamilton, and minor league lefty Shane Drohan.
Kyle Harrison, the headliner of this trade, is a promising 24-year-old pitcher who was recognized as a top 25 prospect in Major League Baseball ahead of the 2024 season by prominent sources such as Baseball America and MLB Pipeline. After making his major league debut in 2023, Harrison has made 42 career appearances — 37 of which were starts — accumulating a 4.39 ERA over 194 2/3 innings pitched. His minor league statistics tell a different story, demonstrating a stellar 3.39 ERA across more than 350 innings, and an impressive strikeout rate of 13.7 strikeouts per nine innings, highlighting his potential as a future ace.
In addition to Harrison, Milwaukee has gained infielder David Hamilton, known for his speed and versatility in the field. Though not known for his offensive prowess, Hamilton had a successful season in 2024, batting .248/.303/.395 in 98 games, contributing positively with his defense across second base and shortstop. His performance dipped in 2025, raising questions about his consistency.
Shane Drohan, a 27-year-old left-handed pitcher, adds further depth to the Brewers’ future plans. A fifth-round pick in 2020, Drohan’s career has been hampered by injuries, yet he displayed his capabilities during a healthy stint at Triple-A Worcester in 2025, where he posted a remarkable 2.27 ERA over 47 2/3 innings with strong strikeout and walk rates.
For the Brewers, the departure of Durbin is notably impactful. As the team’s starting third baseman in 2025 and a key contributor to their 97-win campaign, his value was evident in his 2.8 WAR. Despite some concerns regarding his offensive metrics, Durbin, who is set to turn 26 soon, appeared poised to be a significant part of the Brewers’ core moving forward.
Monasterio, who has served as a reliable utility infielder, and Seigler, who faced challenges in his rookie season but showed promising signs in his underlying statistics, also played important roles in the Brewers’ lineup.
With Hamilton likely to step in and serve as a replacement for Monasterio, the Brewers now face the perplexing question of who will assume the starting third baseman role come opening day.
Overall, this trade marks a pivotal moment for the Brewers as they reshape their roster for the upcoming season. The acquisition of young, promising talent bodes well for the future, and their ability to balance immediate needs with long-term goals will be crucial as they head into the new season. Much more details surrounding the implications of this trade are expected to unfold in the coming days.
