Bruce Zimmermann: Everything you need to know

The Cardinals reassigned Zimmermann to minor-league camp Tuesday. Zimmermann signed with the Cardinals on a minor-league deal in January after spending the 2025 season in the Brewers organization. The southpaw gave up six runs (five earned) in six innings in a late-season spot start with Milwaukee but otherwise spent the entire campaign at Triple-A Nashville, where he produced a 4.11 ERA, 1.23 WHIP and 109:30 K:BB in 138 innings. After falling short in his bid for a spot on the Cardinals' Opening Day roster, Zimmermann is expected to serve as a swingman at Triple-A Memphis to begin the season.

The Cardinals signed Zimmermann to a minor-league contract Jan. 5 that includes an invitation to spring training. Zimmermann made one spot start with the Brewers in 2025 but spent the rest of the season at Triple-A Nashville, where he held a 4.11 ERA and 109:30 K:BB over 138 innings. The left-hander will compete for a roster spot in spring training, but his likely role will be rotation depth at Triple-A Memphis.

Zimmerman cleared waivers and was outrighted to Triple-A Nashville on Saturday. Zimmerman was brought up to the big-league roster for a spot start Tuesday and was designated for assignment afterward. The 30-year-old will stick around in the Brewers organization after being outrighted. Zimmerman allowed six runs (five earned) across six innings during the start.
