The Cubs have released right-hander Caleb Kilian, according to the transactions log on his MLB.com profile page. The righty was designated for assignment by the Cubs last week and presumably passed through waivers unclaimed in the days since his DFA. The Cubs could have outrighted the right-hander to the minor leagues, but evidently did not choose to do so. He’ll now be eligible to sign with any of the league’s 30 clubs without the club needing to carry him on their 40-man roster.
Kilian, 28 in June, got his start in pro ball as an eighth-round pick by the Giants back in 2019. He made just seven appearances in the minors that year, with 16 scoreless innings between rookie ball and Low-A. That impressive start to Kilian’s pro career was put on hold due to 2020’s canceled minor league season, and when he got off to a hot start with the Giants between the High-A and Double-A levels in 2020, Kilian found himself swapped to the Cubs alongside outfielder Alexander Canario at the 2021 trade deadline in the deal that made Kris Bryant a Giant.
That trade kicked off Kilian’s Cubs career, and he made four starts for the club’s Double-A affiliate down the stretch to finish the year with a 2.42 ERA and a 29.2% strikeout rate in 100 1/3 innings across two levels of the minors. Those were solid numbers for the year and put Kilian on the radar for a big league call-up at some point in 2022. He started the year at Triple-A but got his chance with the Cubs in June of that year. His first outing in the majors was a solid run, as he allowed three runs across five innings of work while striking out six and walking two. Things came apart from there, however, and Kilian struggled to a 14.21 ERA with ten walks in just 6 1/3 innings of work against three strikeouts.
That pair of disastrous outings ended Kilian’s first foray into the majors, and his newfound control struggles seemingly followed him back to the minors. After posting a 2.06 ERA with a 9.1% walk rate and a 24.8% strikeout rate in nine Triple-A starts prior to his call-up, Kilian struggled to a 5.37 ERA with a 14.6% walk rate the rest of the way after being optioned back down to the minor leagues. He managed to rein in his wildness in 2023, but that came at the expense of punchouts; Kilian struggled to a 4.56 ERA in 25 Triple-A outings that year despite walking just 7% of his opponents thanks to a lackluster 18.6% strikeout rate.
Last season, Kilian appeared to be in the conversation for a big league job with the Cubs during Spring Training before being sidelined by a teres major strain for several months. When healthy enough to pitch again, Kilian posted a 3.22 ERA in 44 2/3 innings of work at the Triple-A level. That was a marked improvement, but his 20.3% strikeout rate was still lackluster. He continued to struggle at the big league level in brief call-ups to the majors as well, with a 4.22 ERA and 5.98 FIP in 10 2/3 innings of work that brought his career ERA in the majors down to 9.22.
Coming into 2025, Kilian had an odd Spring Training where he struck out 32.3% of his opponents in six innings of work, but also surrendered 12 hits and wound up with a 7.50 ERA. His first start at the Triple-A level was nothing short of disastrous this year, as he surrendered six runs over 2 1/3 innings of work. That wound up being his only outing with the Cubs this year before they decided to pull the plug and designate him for assignment. Now that he’s cleared waivers and been granted his release, the right-hander will have the opportunity to sign with any of the league’s 30 clubs and try to get his career back on track, though it’s also possible he could look to reinvent himself in independent ball or overseas as well.
