Tanner Scheppers is going to be rehabbing as a starting pitcher while working his way back from injury, and T.R. Sullivan writes that decision is guided in part by a belief by some that Scheppers could be a top of the rotation starter:
There are those who see Scheppers as a future front-of-the-rotation pitcher, a right-hander with a 95 mph fastball, knockout slider and improving changeup who could end up being a No. 1 starter.
Jon Daniels apparently said before the season that the decision to put Scheppers in the rotation was motivated at least in part by a belief he had top of the rotation potential. Scheppers has established himself as a solid reliever, but if he has, say, a 10% chance of being a #1 starter, I think its reasonable to take that chance and let him have a shot at starting.
Sullivan also writes that Scheppers, himself, wants to be a starter, and quotes Mike Maddux as saying that Scheppers "could help us in a variety of roles." With the rotation currently in flux, and Martin Perez and Matt Harrison both sidelined for quite a while, it seems more likely that Scheppers will get another look in the rotation than it appeared a couple of weeks ago.
