Resist the temptation to bring up the true gems(Bailey, Bruce, Votto?) or young guys who could use more time in the minors(for example Dumatrait who’s coming back from injury) too early.
I agree with 99% of what you've written. This being the exception. I agree with what you wrote, but not the example of Dumatrait.
Dumatrait's injury was in 2004. That's 3 years ago. IIRC correctly he is now in his LAST option year. While there's no rush to promote him (I don't think much of him as a prospect) there no reason to pamper him or keep him down on the farm in order to develop. He's 26 and he is what he is.
At AA last year Dumatrait seemed to be able to reach back and dial up some extra velocity and movement ...oh 10% of the time or so. It was unhittable when he did it, but he couldn't do it consistently. You hate to slot guys into relief after spending all their time as starters, but I have to wonder if he might be better suited in that role.
