Cubs Release Chris Flexen

The Cubs released righty Chris Flexen, as first reflected on the MLB.com transaction log. Chicago had designated him for assignment last week. MLBTR has learned that Flexen declined an outright assignment, leading to the release. As a player with five-plus years of service time, Flexen will collect the remaining portion of his $1.5MM salary.

Flexen signed an offseason minor league deal and was called up at the end of April. That initially worked brilliantly. The 31-year-old fired 28 innings of 0.65 ERA ball over his first two months. Flexen’s 13.5% strikeout rate and pre-2025 track record suggested he was in line for significant regression. That arrived in July, when opponents blasted six home runs and tagged him for 15 runs (13 earned) through 15 2/3 innings. He allowed multiple runs in each of his final four appearances.

The Cubs pulled the plug last week. Flexen concluded his organizational tenure with a 3.06 earned run average over 43 2/3 innings. Estimators like SIERA, FIP and xERA all felt his true level was closer to allowing five earned runs per nine — essentially a match for the 4.95 ERA he posted over 160 innings for the White Sox a year ago.

Flexen has the ability to log multiple innings out of the bullpen or build back out as rotation depth. That’ll at least get him interest on a minor league contract, and it’s not out of the question that he finds a big league deal. A signing team would only pay him the prorated portion of the $760K league minimum for the final couple months. That’d be subtracted from the Cubs’ commitments.
