The Cubs signed Milner to a one-year, $3.75 million contract Thursday, Mark Feinsand of MLB.com reports.
Milner will be reunited with manager Craig Counsell, who he pitched for in three of his four years with the Brewers. The left-handed reliever spent the 2025 campaign with the Rangers, collecting a 3.84 ERA, 51.4 percent groundball rate and 58:21 K:BB over 70.1 frames.
