Well this is it folks. This is the final series, the final three games of the 2015 season. That only applies to the Brewers though. The Cubs have already secured a playoff spot as one of the Wild Card teams. That's the intrigue part of this series. As the Cubs are only two games back of the Pirates home field advantage is still up for grabs.
The magic number for the Pirates is two. And combination of Pirates wins and Cubs losses that adds up to 2 guarantees home field advantage for the Pirates. The Brewers will affect that by how well they play in these final two games.
