The Cubs have placed P Lendy Castillo on the 15-day disabled list
The Cubs took Castillo in the Rule 5 draft this past offseason, and they’ve gotten from him about what it was reasonable to expect. He’s appeared in only 7 games – for context, every starter except Dempster, who had a brief DL stint, has made seven starts already – and only 7.2 innings. He’s mixed in a few good outings with the bad, but honestly has looked overmatched. But again, that’s to be expected from a Rule 5 pick making his first appearance above single-A.
I really, really doubt that the Cubs will do anything that could be conceivably construed as rushing him back, since from the front office’s perspective, the disabled list is just about the best place for Castillo right now. They can’t send him to the minors without either sending him back to the Phillies or working out a trade for him, and he’s shown enough talent that I can understand why they aren’t terribly eager to do that if they don’t have to. On the other hand, though, they justifiably don’t want to actually let him play any more they have to in real games. The official story is that he has a strained groin, and he can rest assured that he’ll get all the time he needs to make a full recovery.
