Misiorowski was promoted to Triple-A Nashville on Tuesday, according to MLB Pipeline.
Misiorowski was tagged for six earned runs in his penultimate Double-A start, but he still posted a 2.97 ERA and 0.99 WHIP over his last seven starts at the level, and the Brewers decided to move him one step away from the big leagues. Concerns remain about Misiorowski's control, but not about his stuff, and there is a chance he could be called up to the majors before the campaign comes to a close.
