Seattle Mariners vs. Athletics Prediction

I’m on the over in this one. Gilbert’s got great numbers on the road, but it’s worth noting that he’s never pitched against the A’s in this hitter’s haven of a ballpark in Sacramento. I think the A’s bats can get to him here and while Springs pitched well in two starts against Seattle at home last year, I think this is going to be a struggle with Springs really having issues pitching at home this season. I’ll back the over in this one.
