The announcement was made by President of Baseball Operations and General Manager Matt Arnold.

“Kyle Harrison provides an exciting young left-handed arm to our starting rotation options this season,” said 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.”

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. He enjoyed his greatest success last season after going 5-1 with a 2.27 ERA in 12 games (11 starts) at Triple-A Worcester while producing 67 strikeouts in just 47.2 innings (.185 AVG/1.01 WHIP).

Hamilton, 28, returns for his second stint in the organization. He was selected by Milwaukee in the eighth round of the 2019 First-Year Player Draft from the University of Texas and was traded to Boston on 12/1/21 as part of the deal for outfielder Hunter Renfroe. Hamilton made his Major League debut in 2023 with Boston, where he has played parts of the last three seasons, including his first career Opening Day roster last season. He has made starts at second base (71g) and shortstop (67g) and has 57 career stolen bases in the majors.
