How do you play the baseball game on the back of a dartboard?

I bought a dartboard and on the back there is a game of baseball on it. I read through the instructions, and all it says about the baseball game is that it has the same rules of the real game. I know a lot about real baseball, but can’t seem to figure out how to apply all of that to the dart game. Can someone give me some insight as to how to play it on darts?
