5 free agents the St. Louis Cardinals shouldn’t bring back

Andrew Miller
With an array of injuries, Andrew Miller only pitched in 40 games for the Cardinals this season.
The 36-year-old lefty reliever pitched 36 innings with four holds for the bullpen. He threw 40 strikes, walked 16 batters, and hit five batters by pitch. He did have a 31.7 swinging strike percentage, which indicates he did well in his outings.
Unfortunately, Miller was not what fans were hoping for from the reliever. Miller filled the requirement for his two-year contract that included a club option for 2021. The team gave him plenty of opportunities. The expectation of what he would bring to the bullpen outweighed what was brought. The Cardinals should move on from Miller.
