Call me dour & grumpy. This relates to Dylan's previous post/concern about Oscar Villarreal's April usage pattern.
I know that Oscar "earned" the starting spot over John Patterson. Still, from an organizational strategic point of view, I'd have given JPatt the MLB 5th spot and put Miguel in the swing role, while protecting Oscar down at Tucson with every 5 day starts.
We have a lot to learn about how young pitchers get injured, but it seems to relate to work-loads before age 23 or so. In some ways BK's closer role was a blessing because it under-used his talents (even though he was heavily-used for a closer).
In short, I think the organization is risking some valuable commodities--their young arms--to address some immediate concerns. I agree that Oscar was better this Spring--it just didn't maximize all the resources: Oscar, JPatt & Miguel. You'd find out if John Patterson could pitch at the MLB level or not by giving him 4 good starts, then move on if he couldn't. You'd protect the 21 year old's arm (not to mention the 20 year old's) in the minors. On a different board, schillingfan proposes that BK had maturity problems because he was promoted too quickly--wouldn't Oscar Villerreal & Edgar Gonzalez be put at risk too?
Of course, I believe that BK should have been used as an inning-eater to protect younger arms, instead of having the younger arms being used as a reason to trade BK.
