Why would it only work in a points league?
If you were confident enough to draft a pitcher you have to go with him unless he's got a bad match-up ie. Coors.
Having said that I've drafted Mussina and Ollie Perez in a couple of leagues and won't be giving either of them the ball early on.
But no, in answer to your original question, pitchers don't statistically have an ordinary first up performance. They get those out of their system in ST.
