Ramirez was claimed off waivers by the Brewers on Tuesday.
DFA'd by the Cubs a week-and-a-half ago, Ramirez will now join the Brewers, adding another right-handed arm to the bullpen. The 27-year-old made eight appearances for Chicago, posting a 4.70 ERA while notching 10 strikeouts and eight walks across 7.2 innings. To clear a spot on the 40-man roster, the Brewers DFA'd infielder Colin Walsh.
