Seattle Mariners vs. Athletics Prediction

I’m on the Mariners here. It’ll be interesting to see how Hancock does in this hitter’s haven of a ballpark in Sacramento, but Severino has struggled in this ballpark as a member of the A’s. The Mariners broke out offensively in a big way on Monday and get an even better matchup here. Give me the Mariners in this one.
