Well, this is awful. The Pirates will be replacing one of their best hitters with Jason Jaramillo until late June or so.
Robinzon Diaz, unsurprisingly, will take Doumit's place on the roster. As I've said before, Diaz is basically Jaramillo but he's a righty and he's a little bit worse at everything. Look for him to pick up some at bats against lefties.
