They got shutdown by a great pitcher. This is why pitching is so important. Really good pitching usually means your really good hitting doesn't matter. Having the good hitting helps a lot of course, but head-to-head, I'll take the stud pitcher vs. the line-up full of mashers.
I'm not too upset about this loss to this pitcher. In fact, I'm thrilled by Ashcraft's outing. A great sign for the rest of the season.
