The Brewers designated Rom for assignment Sunday.
Rom will give up his spot on the 40-man roster to outfielder Ji Hwan Bae, who signed a minor-league deal with the Brewers earlier Sunday before being elevated to the big leagues after Cooper Pratt (hamstring) moved to the injured list in a corresponding move. A 26-year-old lefty, Rom was previously up for two stints in the majors earlier this season, logging a 3.18 ERA and 1.76 WHIP in 5.2 innings over five relief appearances.
