At the Oracle, you can watch a baseball game for free in a space called the "Hole in the Wall Club." It was set up by the Giants a long time ago. It's right next to the Bay; you show up here and if there's room, you can watch the game for free.
The stadium clears the room every three innings to give everybody a chance to watch, but if there's not many people around you can watch an entire game. Making it even better: they sell hot dogs here!
So don't worry about the cost of a game: just show up.
