After spending eight seasons with the Minnesota Twins, left-handed reliever Caleb Thielbar has signed a one-year deal with the Chicago Cubs. The Cubs are adding a pitcher known for his ability to handle left-handed batters and for consistently stranding runners throughout his career. At 37 years old, Thielbar brings a wealth of experience and a solid track record to his new team.
Cubs Sign Caleb Thielbar to Strengthen Bullpen
Caleb Thielbar’s MLB career as a reliever began in 2013 at the age of 26, and he quickly made an impression. In his rookie season, Thielbar was nothing short of dominant, posting a remarkable 1.76 ERA, a 0.826 WHIP, and an ERA+ of 233 over 46 innings, establishing himself as one of the league’s most effective bullpen arms. In his second season, while his ERA and WHIP increased to 3.40 and 1.406, respectively, he remained a reliable and resilient presence in high-leverage situations, finishing with a strong 116 ERA+.
Over the years, Thielbar has continued to prove his value as a steady veteran in the Minnesota bullpen. Although 2023 was marred by injuries that limited him to 30.2 innings, he still posted a solid 3.23 ERA and an outstanding 0.946 WHIP, striking out 36 batters while walking only six. His performance in 2023 reaffirmed his reliability, despite the setbacks. However, 2024 presented a challenge, as Thielbar struggled with a 5.32 ERA and a career-high 24 walks in 59 appearances. Nevertheless, he still managed to strike out 53 batters, maintaining a solid 10.1 K/9 innings rate.
Bullpen Impact
Thielbar’s wealth of experience and proven track record make him a valuable asset for the Cubs, particularly as a left-handed reliever. Over the course of his career, he has been highly effective against left-handed batters, who have consistently struggled with him, posting low batting averages and OPS figures. This makes him an ideal candidate for high-leverage situations against left-handed hitters, which the Cubs will likely target him for.
In addition to his on-field skills, Thielbar brings a decade of veteran leadership to the bullpen. At 37 years old, he can offer guidance to younger pitchers, helping them with their mechanics and approach to the game. While his 2024 season showed some signs of wear and tear from his long career, his recent performances demonstrate resilience, durability, and the ability to still contribute meaningfully at the major league level. For the Cubs, signing Thielbar represents a move to bolster their bullpen with a proven, experienced reliever who can still be effective in crucial situations.
