I agree with jokin, they are sending him down because they don't need any pitchers for a week or so, so he gets to go to Rochester and pitch. When they need 5 starters again, and Hernandez is bad, Hendriks will be back (or Gibson, frankly). Really, this is more a demotion because Gibson will be ready when they need a 5th pitcher, than it is about Hernandez, imo. Because heaven knows you have to keep room for Pelfrey and Correia.....
