Although they are both scheduled to pitch again on Monday, a couple of recent news items have people speculating that Shelby Miller will beat out Joe Kelly for the 5th starter job.
The first is that Miller will be making the start on Monday with Kelly working in relief. This is the second time in a row that Miller has gotten the start and an indication that the Cards want him to get into a pre-start routine.
The second, and most important news, is that Jason Motte will likely start the season on the DL. While it may not seem to have an impact on the 5th starter role, it does. For one thing, it means that Kelly, Miller and Fernando Salas will all most likely make the opening day roster and since Kelly is better suited for relieving, it follows that he would be the long reliever in the pen.
Motte's injury pushes Mitchell Boggs into the closer role, with Trevor Rosenthal as the likely setup man.
Here is the projected starting rotation and bullpen:
