There are a lot of guys who will be very important to the Cardinals success in 2013.
But they keystone player might just be Trevor Rosenthal.
The team has plenty of offense coming back. The bench will be at least somewhat improved and there is a huge infusion of talent on the way.
But the biggest shortcoming of the team is the starting rotation which will be without Kyle Lohse and Chris Carpenter for the season. Rosenthal can't fill both of those spots. But what he can do is be ready every day to come into a game in the sixth inning and get a key out with a strikeout.
The Cardinals could take a lot of pressure off the rotation and basically allow them to be a bunch of five inning pitchers if Rosenthal is available to pitch the sixth, Edward Mujica comes in for the seventh, Mitchell Boggs is there for the eighth and Jason Motte can handle the ninth.
Its a plan that's workable. But I still wish the Redbirds could strike a deal to bring back Kyle Lohse, who still doesn't have his desired long term contract as spring training opens to pitchers and catcher.
Lohse did a great job last year filling in for Carpenter at the front of the rotation when he was injured and filling in for Adam Wainwright the year before.
