Padres vs Mariners Prediction
The Padres are 4-1 in their last 5 meetings against the Mariners and are 2-1 in their last 3 visits in Seattle.
In this Padres vs Mariners Prediction, the Mariners are coming as -160 home favorites. The Mariners have the pitching advantage today as Gilbert goes up against Walker Buehler. Gilbert finally got back on track with zero and one earned runs in two of his last three starts and Buehler has been target practice on the road with a 10.12 road ERA. On top of that, the Mariners have the second-best bullpen in baseball and are in a bounce-back spot at home today, so I expect them to win this one. Take the Mariners on the moneyline.
