The Pirates have lost Deolis Guerra to the Angels in the Rule 5 Draft.
This is a little weird, since the entire reason Guerra was in the Pirates organization in the first place was that they recently re-signed him to a minor league deal. By selecting Guerra, the Angels are placing him on their 40-man roster. One would think their willingness to roster him would have allowed them to sign him in the first place if they had wanted to. It would have been nice for the Pirates to keep Guerra, particularly on a minor league contract -- he isn't a great pitcher, but he's terrific as depth goes.
But whatever. This practice of drafting a recent minor league signee does occasionally happen. In fact, I believe the Pirates' selection of Victor Santos in the 2006 Rule 5 Draft came shortly after he signed a minor league deal with the Royals.
Anyway, the Pirates passed on their pick in the major league portion. So they won't be adding anyone they'll have to place on their roster. They also didn't lose anyone besides Guerra, so all the prospects we were mildly worried about the Bucs losing, like Clay Holmes, remain in the organization.
