Seattle Mariners vs. Chicago White Sox Prediction
I’m on the under here. What this boils down to for me here is that I don’t trust the White Sox offensively on a good day, and I don’t trust them really to do a whole lot of damage here. On the other side, Shane Smith has been the bright spot of this White Sox rotation, and I think this could end up being a low-scoring game just because of a lack of offense on both sides and in what could be a first-to-3-wins kind of game. Give me the under.
