Mariners vs Nationals Prediction

I’m on the Nationals here. I just think that the Nationals have a clear edge in starting pitching. While I’m not always sold on their relief pitching, I think that the Nationals can carry over some of their success at the plate from Wednesday’s win against Emerson Hancock, who has really struggled at home this season. Give me Washington in this one.
