Dustin Pedroia. He plays for the love of the game, and his spirit is in it to win it. I really believe he would be playing even without the money and fame. That kind of passion I can only dream about right now.
After the last playoff game in either 2008 or 2009, Mr & Mrs Dustin Pedroia flew to Phoenix (they are from the Phoenix area). I was sitting in first class, two rows behind the Pedroias, and later saw them in the baggage claim area after we landed. Two impressions: Mrs. P is very beautiful, and Mr. P is not very tall. :)
