The Brewers placed Kuhnel on the 15-day injured list Saturday, retroactive to July 3, due to a right shoulder injury.
Kuhnel has been struggling of late, giving up five runs (four earned) over three innings across his past three starts. It's not clear if the shoulder issue was to blame to any extent, but he's now going to be out through at least the All-Star break. The Brewers recalled Craig Yoho from Triple-A Nashville in a corresponding move to fill Kuhnel's spot in the bullpen.
