If you are still wondering how in the world Justin Morneau won the award, over arguably more deserving candidates. Go no further than here for the individual votes.
Feel free to record the atrocities.
I will get you started: Mauer was placed tenth by a Minnesota beat writer. I'm all for being impartial but it seems to me that a guy who covered the Twins day-in and day-out would have valued the catcher's contribution a little higher than that.
I haven't been able to find the National League equivalent list of the voting on any of the senior circuit awards. I can only assume that the New York media didn't think a home player was screwed in those awards and therefore didn't feel the need to throw its colleagues under the bus. I could be wrong about their motives, of course.
