What makes it difficult is that a player needs to be good himself, but also depends on teammates, which can backfire too. Let's say Beltre keeps up his production, to get all those RBI he will need, it means Ichiro keeps playing well and that would make winning the Batting title that more difficult.
I think Pujols has a shot, but not many others.
My apologies. I have a nephew named Anfernee, and I know how mad he gets when I call him Anthony. Almost as mad as I get when I think about the fact that my sister named him Anfernee.
