I think the MVP should be the player who is the msot important player relative to the rest of his team as well as to his team's success within the league. Therefore, if the Guardians had made the playoffs this season I would likely have said Hafner. Since his tremendous performance didn't have the mythical quality of keeping his otherwise mediocre team in the playoff hunt, then he probably doesn't deserve MVP.
If he plays on an excellent team then his season doesn't have to be mythical it simply has to be very very good. Jeter is having an MVP caliber season. So is Ortiz. So is Dye.
It definitely could go to Ortiz though. He's having a season that's as good as last season, and there is nobody putting up A-Rod type numbers. The sox may not have won enough to make him MVP, but he has done all he can, that's for sure.
