That's true. Isn't there some prevailing theory, though, that the pitchers start out the season "ahead" of the hitters? I don't want to curb our enthusiasm about these guys, because I'm as enthused as anyone, but I just want to know at what point their contributions will be deemed legitimate enough to be considered reliable.
Another way of putting it would be: At what point do Cueto and Volquez's performances stop being simply a question of "small sample size" and more a question of repeatable dominance?
