Toro was optioned to Triple-A Nashville on Thursday, Curt Hogg of the Milwaukee Journal Sentinel reports.
The 26-year-old was recalled from Nashville last week and appeared in three games while up with the big club, going 4-for-10 with a home run, a walk, four RBI and three runs. Toro could return to the majors later in the season when the Brewers need infield depth.
