MILWAUKEE — The Milwaukee Brewers' starting third baseman Caleb Durbin is among the players headed to the Boston Red Sox in a trade confirmed Monday by the team.
The Red Sox will receive Durbin, SS Andruw Monasterio, 2B Anthony Siegler, and a Comp B pick.
The Brewers will receive LHP Kyle Harrison, 2B David Hamilton, and LHP Shane Drohan.
"Kyle Harrison provides an exciting young left-handed arm to our starting rotation options this season," said President of Baseball Operations and General Manager Matt Arnold. "At just 24, he already has valuable Major League experience under his belt, and we look forward to watching him progress as a Brewer."
Arnold added, "We are also pleased to add Shane Drohan and David Hamilton to the organization. Shane is another left-handed arm who has shown strikeout ability over his Minor League career and is a candidate to contribute to the Major League rotation this season. David brings to us a versatile infielder and quality defender up the middle who has shown the ability at the big-league level to impact games with his speed."
The following information the players involved in the deal was provided by the Milwaukee Brewers:
Harrison, 24, was selected by San Francisco in the third round of the 2020 First-Year Player Draft out of De La Salle (CA) High School. He entered the 2024 season as the top prospect in the Giants organization according to Baseball America and MLB Pipeline. He was also tabbed by MLB Pipeline as the top left-handed pitching prospect in baseball entering the 2023 and 2024 seasons.
Harrison, who is under club control through the 2030 season, owns a career record of 9-9 with a 4.39 ERA in 42 games (37 starts) with San Francisco (2023-25) and Boston (2025). He was traded by the Giants to the Red Sox with three others last June 15 as part of the deal that sent infielder/designated hitter Rafael Devers to San Francisco. Harrison went a combined 1-1 with a 4.04 ERA in 11 games (6 starts) between the two teams last season.
Drohan, 27, was selected by Boston in the 2020 First-Year Player Draft from Florida State University. He has spent all of his Minor League career (2021-25) in the Red Sox organization with the exception of 10 relief appearances in the White Sox system in 2024. Drohan has recorded 472 career strikeouts in 411.2 innings pitched (10.32 K/9IP) while holding opponents to a .239 batting average.
