Championship game stadium
To get the field that you play the championship in, simply win the world series undefeated (by going 4-0 in the series) and then create a new coach and team then choose that field as your home field. (this is the stadium where you play the all-star game at also, it is the one with the hot dog holding a bat, behind the center field wall.)
