Chicago White Sox vs. Seattle Mariners Prediction
I’m on the White Sox here. I just think that this is probably the most winnable spot of the series for the White Sox as I’m not buying into Miller after one start and while he didn’t look great in April, Kay has started to turn things around a bit as of late and I think that this ends up being a solid start as the Mariners have stunk it up against lefties. Give me the White Sox.
