The Brewers optioned Perkins to Triple-A Nashville on Tuesday.
The 29-year-old hasn't started a game since June 29 and has just six at-bats over the past two weeks, so the Brewers will send him down in favor of top prospect Luis Lara. Perkins could get another look with Milwaukee if its outfield depth is tested later this summer, but his .157/.250/.258 slash line in 53 plate appearances is unlikely to result in him working as more than a bench player.
