Oh, yes, I forgot about The Rookie, and I even own it. Ken Burns's "Baseball" is great too. When I can save up enough money I'm going to buy it on DVD, even though I already have it on VHS. I watch the whole thing about once a year.
From the official rulebook of baseball: "Baseball is a game played between two teams of nine players each." Therefore, baseball is a game played only in the National League.
