St. Louis’ bullpen was a principle reason behind their success against the Los Angeles Dodgers in the NLCS.
The Cardinals can count on talented relievers like Trevor Rosenthal, Seth Maness, Carlos Martinez and Kevin Siegrist—all of whom have showcased St. Louis’ ability to develop young arms.

Boston can count on veteran arms like Koji Uehara, Junichi Tazawa, Craig Breslow, Brandon Workman and Ryan Dempster.
