I think there's a good chance he turns into a perennial 30 HR guy. Just look how much he's improved in the past year, you don't think he can turn all those doubles (third in the majors) into HR's in a coupel years/next year?
Mike Lowell went from being a 20 HR guy with a ton of doubles at age 28 to one of the best HR hitters in baseball at age 29/30. I wouldn't say the amount is infantesimal, especially for players in their first full big-league season.
