Farris, 26, was called up for just one day last July as an emergency fill in when Rickie Weeks went on the disabled list. He grounded out as a pinch-hitter against the Cubs in his Major League debut.
Farris is mainly a second baseman, but played shortstop Thursday and Friday to prepare for his recall. He got the nod over Nashville shortstop Edwin Maysonet because he is already on the Brewers' 40-man roster, which is full.
Farris, a California native, was hitting .161 in nine games at Nashville, but batted .271 and stole 21 bases for the Sounds last season. A fourth-round selection in the 2007 First-Year Player Draft out of Loyola Marymount, Farris is ranked as the Brewers' No. 17 prospect.
