The Brewers recalled Rom from Triple-A Nashville on Sunday, Adam McCalvy of MLB.com reports.
The left-hander was optioned to Nashville on June 22 but is back in the majors since Brandon Woodruff (shoulder) is headed to the injured list. Rom gave up just two earned runs and struck out 10 across his 5.1 frames with the Brewers, though he also allowed six hits and four walks.
