There's value here. Pujols is a monster of course, and then there are some decent hitters besides him in the STL lineup, but half of it is very weak. Pitt is more complete up and down the order.
Snell can be great and also can get bombed, but Looper is not an experienced starter, he will probably get tired early as he did in his last game.
Pitt has the edge here, their odds shouldn't be equal to STL's.
