Billingsley is in the pen right now, and he isn't doing very well either. Until either his performance improves or he is sent back down to Triple-A to figure things out, he is going to stay in the bullpen. Yahoo must have gotten this one wrong, I've got to assume that Hendrickson will be starting tomorrow.
