You can never assume a sweep, even over the worst teams in baseball. That being said, if we knew right now that the Brewers were going to pull off a sweep against the Tigers at Miller Park this weekend, they would have a legitimate chance to catch the Cubs for at least a tie of the division title. The room for error is thin, but if the Brewers split the last two games of the Cardinals series and win out versus the Tigers, the Cubs would have to finish 4-2 versus the Pirates (3 remaining games) and Cardinals (3 games) in order to win the division outright.
