Rick Peterson is expected to be announced as the new pitching coach of the Milwaukee Brewers on Tuesday, according to a report in the Milwaukee Journal Sentinel.

Peterson, the former pitching coach with the Oakland A's and New York Mets, worked with Brewers manager Ken Macha and third-base coach Brad Fischer in Oakland, and Brewers bench coach Willie Randolph in New York.

Peterson will be charged with helping turn around a Brewers staff that posted the second-highest ERA in the National League this season, including the worst mark among starters (5.37 ERA).
