Hader was called up from Triple-A Colorado Springs on Friday.
EDGE Analysis
Hader has struggled this season at the Triple-A level, but he remains the Brewers' top pitching prospect, and the club decided it was time for him to show what he can do at the top level. Hader worked exclusively as a starter the last two seasons, but it remains to be seen if he will work in that role for the Brewers, or open in the bullpen.
