Brieske (elbow) will begin a rehab assignment Wednesday with High-A West Michigan, Chris McCosky of The Detroit News reports.
Brieske has been on the injured list all season, so he will likely require a handful of starts in the minors before he's ready to make his season debut. The 25-year-old righty posted a 4.19 ERA and 1.20 WHIP through 81.2 innings across 15 starts last season.
