Seattle Mariners vs. Chicago White Sox Prediction
I’m on the Mariners -1.5 here. I get the case to be made for a home underdog in some spots, but the White Sox just are not a team I want to take a stab at right now in any way, shape, or form. The Mariners have some huge confidence after their sweep of the Padres, and while Castillo’s struggled on the road this season, this is just a huge mismatch in favor of the Mariners, so give me Seattle -1.5 in this one.
