In this Athletics vs Mariners Prediction, the Mariners are coming as -190 home favorites. As much I would like to ride the over in this series, this is a bounce-back spot for the Mariners in an excellent price. They are getting Bryan Woo on the mound, who has been elite at home with a 7-1 record and 2.63 ERA, while Jump has given up 5+ runs in three of his last road starts. On top of that, the A’s have the worst bullpen ERA in baseball so I will lay the chalk and get the Mariners on the moneyline for a nice bounce-back win.
