The Brewers optioned Black to Triple-A Nashville on Thursday.
Black will cede his spot on the 26-man active roster to outfielder Blake Perkins (calf), who was reinstated from the 10-day injured list. After getting recalled from Nashville on Aug. 12, Black started at designated hitter in five of the Brewers' ensuing nine games while going 2-for-15 with three walks against five strikeouts. Now that Black is out of the mix, the Brewers will likely rotate a number of players at DH, with Gary Sanchez, Jake Bauers and Perkins all being candidates to see upticks in opportunities.
