10 Cards, BP-551 to BP-560The Ballparks Expansion adds 10 cards that provide a new game mechanic, Home Ballpark. When playing with Ballparks, each player is dealt two random ballpark cards and selects one for their home ballpark. The other card is discarded face down. Whenever a player has the Home Field, the effect of their home ballpark applies. Ballpark effects apply to both players.
This is an expansion to the Baseball Highlights 2045.
