Take ARod. RJ would be a fine choice if you want your best player to be a pitcher, but I'd take ARod. His numbers are up with, if not the, best in the league and then tack on the fact that he's at a shallow position. Don't go for Vlad and his 40-40, as steals are too hard to predict in head to head. He might steal 5 bases one week and none the next. With ARod, you know you're getting the power numbers day in and day out.
The odds of the AL MVP coming from the American League are looking pretty good.
