Roenicke, 58, has been with the Brewers since 2011. It has been his only stop as a manager.
In Roenicke's first year with Milwaukee, the Brewers won a franchise-record 96 games. They won their first NL Central title in 29 years but lost to the eventual World Series champion St. Louis Cardinals in the NLCS.
There had been speculation the Brewers might fire Roenicke after the team's second-half collapse last season but the team announced in October that he would return in 2015.
The Brewers led the division by 6.5 games on July 1, and held the division lead for a total of 133 days. They were tied for the division lead on Aug. 31 but went 9-17 in September and finished eight games behind the Cardinals in the division.
