Their pitching has overachieved to amazingly unsustainable proportions. Their offense hasn't really been able to hit much this year. Not really. They have a extremely high strand rate, but they've still pitched great, just better than their FIP, which is still second to only the Dodgers in all of baseball. So no, they haven't overachieved to amazingly unsustainable proportions. And whenever a team gets blown out, they look terrible. Judging their season performance based off the last two games is silly as the people who judge players off having a bad post season series. But I get it, your Cubs fans who hate the Cardinals, so logic isn't really what you're going to be using when evaluating a rival. Between the Cardinals fandom and the fact that your screen name's only contribution to society was Sable, you're on my list.
