Peralta (calf) is set to return to the Brewers this weekend in Philadelphia, Todd Rosiak of the Milwaukee Journal Sentinel reports.
Peralta has been out since June 21 with a right calf strain, but has been able to spend the past couple of weeks with Triple-A Colorado Springs on a rehab assignment. He tossed two innings against Omaha on Thursday, retiring all six opposing batters while sprinkling in a pair of strikeouts. Peralta figures to rejoin the bullpen upon his arrival, where he spent over a month getting used to his new role before landing on the disabled list.
