Why isn't J.A Happ pitching as a starter in the world series?

Question

I know hes a rookie but he performed a really good season. Besides he's done much better than Blaton in the regular season. Or am i incorrect?

Answer 1

It's not that he did better than Blanton its that Blanton has had more experience and Charlie Manuel believes Blanton will do better in this situation right now then Happ will.

Answer 2

Because Charlie Manual has not selected him to be a starter.

The REASON for that remains a mystery.
