The Cubs are re-signing veteran left-handed reliever Caleb Thielbar, per Jesse Rogers and Jeff Passan of ESPN. The agreement between the two parties is still pending the completion of a physical. Thielbar is represented by ISE Baseball.
Thielbar, 39 in January, spent his entire career prior to the 2025 season with his hometown Twins. He signed a one-year, $2.75MM contract coming off a down showing in his final year with Minnesota and bounced back in a major way with Chicago.
In 58 innings this past season, the South Dakota State product notched a sharp 2.64 earned run average and 25 holds — the latter tying him with Brad Keller (also a free agent this winter) for the team lead. Thielbar struck out 25.5% of his opponents, limited walks at an excellent 5.9% clip, and kept 40.7% of the batted balls against him on the ground (a career-high mark). He tacked on another 3 2/3 scoreless frames in the postseason.
Thielbar is the third free-agent addition to the Cubs’ bullpen this winter, joining fellow southpaw Hoby Milner (one year, $3.75MM) and right-hander Phil Maton (two years, $14.5MM). Thielbar and Milner give manager Craig Counsell a pair of experienced southpaws, both of whom he’s previously managed, and create the potential for a trio of southpaws, should Luke Little also make the club. Thielbar, Milner and Maton will combine to help bridge the gap between the rotation and young closer Daniel Palencia.
More to come.
