Chicago White Sox vs. Seattle Mariners Prediction
I’m on the White Sox here. I get the case to be made for Seattle at home with Hancock going at a pitcher friendly ballpark, but the value lies with Chicago who are still playing some solid baseball right now and I just don’t think there’s as much of a pitching discrepancy here with Burke pitching his best ball on the road. Give me Chicago.
