Edward Valdez - Great start his first time out, but he's organizational filler.
I think he may be a marginal prospect. From what I've read, they think he has good stuff. He's what, 25-26? A little old, but he has advanced a level almost every year (meaning he was older than originally thought, I'd assume), and does not appear to have hit a wall in AA this year. I think they'd consider him for a shot at the major league bullpen.
