1. Dustin PedroiaPrevious ranking: 1
It's fair to say this hasn't been Pedroia's most enjoyable season so far. He's hitting just .271 with a .735 OPS, his production hampered in part by a thumb injury that probably should have landed him on the disabled list. And his defense of Kevin Youkilis earlier this season could also have been interpreted as an admonishment of his manager. For the Red Sox to turn this mishmash of a season into a memorable one for the right reasons, it's imperative that Pedroia stays healthy, performs with his usual passion and production, and is a unifying force in the clubhouse even if he's not the leader of the Bobby V. fan club.
