Series Preview Cards Mets For Opening Day Real baseball is finally here. But if you were busy enough keeping up with the Cardinals this spring and haven't had time to brush up on their opponents, you've come to the right place. In collaboration with some of the best bloggers and podcasters the internet has to offer, I'll be introducing you to the Cardinals' opponents, one series at a time. First up, Roger Cormier and the New York Mets. Follow Roger on Twitter @GoodFundies (which, if you didn't know, is short for Good Fundamentals), listen to his podcast with Brian Mangan on iTunes, and read even more from Roger at Fangraphs.
