Mike Lowell, 3B
Fast fact: Sixteen of his 21 home runs came against AL East opponents.
Lowdown: Just because Lowell signed that big contract in the offseason doesn't mean he'll replicate his 2007 numbers. With Manny Ramirez and David Ortiz both hitting fewer home runs than normal, that left men on base for Lowell, who crushed the ball in Fenway Park (.373 batting average, .993 OPS) and finished with 120 RBIs. That almost certainly won't happen again.
