Everyone wants to point to past postseasons, but the majority of these guys weren’t even here for that. So you try to downplay it going into this series against the Cubs and call it any other Division Series, you say you just want to advance.""But the rivalry between these two teams — I feel like it’s been our two teams going at it the last eight years. All of the storylines there. We just really wanted to perform for our city and this organization and our fanbase. We knew it meant a little bit extra.” Yelich saidChristian Yelich celebrating in the clubhouse after the Milwaukee Brewers qualified for the NLCS - Source: GettyNow, the Brewers will hope to carry this momentum forward and make it to the World Series for the first time since 1982.
