well I speak for myself here so take this with a grain of salt, but if I didn't know the name of the closer on the team and at least the most active relievers I would do a little more homework before laying any dough on the teams. I have a lot of friends from outside of Vegas send me money to bet for them, if they can't name any of the bullpen pitchers I usually will book the bet myself and save the gas driving down to the book if you catch my drift. As far as how the pitchers are doing lately I use MLB.com to look up stats.
