Brewers manager Pat Murphy said Friday that Frelick (shoulder) will begin a rehab assignment soon, Casey Drottar of MLB.com reports.
Murphy noted that Frelick will likely be limited to designated hitter duty initially on his rehab assignment as he works his way back from a right shoulder strain. Frelick played though shoulder discomfort for much of the season before he finally landed on the 10-day injured list in mid-July. He should return before the end of August if he can avoid a setback.
