It's the curse of the Asian pitchers (Nomo/Matsuzaka). They come to america with some kind of pitches that American's have never seen and then the are worthless two years later when everyone's figured out how to hit their stuff or they break down trying to throw hard all the time. You have to have the velocity and stamina to be unhittable year after year, and they aren't normally suited for that. Hopefully he can have a decent enough record to help the Sox get to the World Series again.
