The only person to blame for the losses is Gagne. I'm sorry, but that's the way it is. I don't care if Okajima is taken out for Gagne, it shouldn't matter. Gagne should be able to get those outs. Personally, I think it's irrelevant whether or not outs were taken away from Jima. It rests on Gagne's shoulders.
That said, I was at Sunday's game against the Orioles, and it made no sense to take Okajima out. However, Gagne should have been able to get the job done. Period.
I think Gagne will be fine though.
