I think this is the most likely round for Hall.... the easiest one to carry five position players, and you don't really need two utility guys. But, they are also going to want pinch-runners.
The Cards' two best relievers are righthanded so I think you just come up with a plan of who you would actually PH for against them in a close game (Vierling yes, Bohm probably, Castellanos maybe, Hoskins no. Marsh and Stott?). If they play the Cards, obviously.
I'm skeptical they are going to do it but think I am in favor of it.
