Little Help?

Whats that baseball betting game where, you put all the position numbers in a hat, and people randomly pull 1 or 2 out or however many you have to so where everyone has an equal number of positions. So if I pull a 2, than any time either catcher from either team gets a single, everyone gives me a dollar. A double, I get 2 dollars, a triple 3, a homer 4. But if the catcher grounds out, I owe everyone a dollar, strikes out swinging 2, strikes out looking 3. Or something like that.

Anyways if anyones familiar with this and knows the rules better than I do I'd definitely appreciate it.
