How does Dustin Pedroia have a MVP award?

Im not saying his stats in 2008 werent good, but he wasnt even the most valuable player on his team that year. i would have voted for youkilis if i had to vote for a red sox player, and i would have voted for Ian Kinsler if i had to vote for a 2nd basemen. its just weird that he neither had the best stats on his team or at his position
