Rosenthal, Carpenter ready to help now

For years, the St. Louis Cardinals have been open to creativity in the way they construct the roster. For example, the 2006 Cardinals won a World Series with unproven Adam Wainwright thriving at closer, and in 2011 slugger Allen Craig was used at second base to get his bat into the lineup. Well, the current Cardinals boast another emerging young right-handed pitcher slated for bullpen duty and another older hitter with promise learning a new position.
