Just 27, Prince Fielder will shoot up future Greatest Fat Players lists if he keeps up the pace he's posted in his first 5+ full seasons. Since his first full year in 2006, Fielder has already clubbed 218  (and counting) homers, and currently has an excellent .927 career OPS. Alas, he's a vegetarian, so we can't chalk his success up to cheeseburgers.
