The Brewers recalled Miller from Triple-A Nashville on Friday.
Miller has bounced between Milwaukee and Nashville all season, and this promotion comes as a result of Bennett Sousa (shoulder) and Jake Cousins (shoulder) both landing on the 15-day injured list. Miller holds a 6.75 ERA and 1.20 WHIP through 6.2 innings in the majors and is unlikely to pitch in high-leverage situations.
