While it may be inevitable that Somebody is moving to the American League, Mike Scioscia (who is on baseball's Special Committee for On-Field Matters) hasn't heard anything about the whole No Division thing:
"I haven't heard anything about eliminating divisions -- I don't think that works. I think divisional play and the geographical rivalries that come with it are important. More teams have opportunities to get to the playoffs in five-team divisions."
We didn't come out here to play tiddlywinks, son.
