The back end of your bullpen should not be 35+ year old pitchers who have lost their stuff. It should be stocked with guys like Belisle, Shackelford, and in my opinion Ramirez who can learn on the job and work their way into a more vital role. If White bumps Belisle, Wagner, or Shackelford, I will be very concerned.
FWIW I agree with what you write here. I think the best way to introduce a potential starting pitcher to the major league roster is to let him get his feet wet in the swingman/blowout role and as he succeeds there, put him into a bigger role. I think Earl Weaver was big on that.
For some reason, the reds don't do that.
Guys come up too fast, get plugged into the starting rotation,
They have a decent turn or two.
The league adapts to them, but they don't adapt to the league.
They start to get shelled.
They get taken from the rotation and moved to the pen
It's weird and we can't blame it on Gullet anymore.
