You can bet on more than one outcome. So if you think we will sweep bet 300. Then to cover your bases bet 100 on 2 wins so if we only win 2 you come out even, and if we sweep you come out ahead. Of course if we only win 1 or 0 you are down.
I was really hoping that betting against them and making this vBook to seem that they would get swept would help get them going and it seems to have done the trick. 3 innings away from a road sweep.
