Zimmermann’s promotion comes with the Brewers dealing with a rash of health problems, including in their rotation. Left-hander Brett Anderson went on the 10-day injured list with a strained hamstring last week, while replacement Zack Godley landed on the 10-day IL after one start because of a finger issue. Worst of all, the Brewers placed star righty Corbin Burnes on the IL on Wednesday, likely on account of a positive COVID-19 test.
Zimmermann was a standout in his own right earlier in his career, though his production has tanked since he left the Nationals for the Tigers on a five-year, $110MM contract prior to the 2016 campaign. The former workhorse threw 514 1/3 innings with Detroit, including just 5 2/3 last year, and pitched to a woeful 5.63 ERA. As a result of that miserable stretch, Zimmermann was unable to land a guaranteed contract during his trip to free agency this past offseason. The 34-year-old sat on the open market for a few months before signing a minor league deal with the Brewers in February.
