If someone wants to make this a poll feel free...
I would say the top players are Pujols, Arod, Hanley Ramirez, Johan Santana, Roy Halladay, Vlad, Morneau, David Wright, Manny
I know I am a Cards homer but I have to go with Pujols, he has the stats of Arod but he has postseason success both personal and team
