Peralta (shoulder) will throw a bullpen session Friday, Adam McCalvy of MLB.com reports.
Peralta felt good after playing catch Thursday, and he'll be able to resume mound work Friday. Following Friday's throwing session, the right-hander is expected to take a few days off before throwing another bullpen. If he feels good after each bullpen session, Peralta hopes to rejoin the Brewers' rotation late next week or sometime next weekend.
