That is a move that several people have suggested, and one that could workout for Ian Kennedy. It seems somewhat inevitable that the Kansas City Royals make that move if he repeats his performance from last season.
If he were to be on the move to the bullpen thanks to a struggle, it would not be an immediate snap of the fingers. There would be a lot of moving parts to this. It seems like the replacement is already in mind.
With the way the roster looks to be shaking out, there are two roads for the Kennedy bullpen transition to take.
