Orioles vs Mariners Prediction

The Orioles are 6-2 in their last 8 meetings against the Mariners, and 4-2 in their last 6 visits in Seattle. Under is 3-1 in their last 4 meetings in Seattle.

In this Orioles vs Mariners Prediction, the Mariners are coming as -147 home favorites. The Mariners are rightfully favored, as they have a far better overall record, and have been above average at home, while the Orioles have been terrible on the road. the Mariners are putting Kirby on the mound, who has not been himself this season, and even though the Mariners have a better bullpen, I don’t trust Kirby.

The Orioles have the fourth-worst bullpen ERA, and both teams are better against righties, averaging 9 runs per game against right-handed pitching. Sugano’s advanced stats show that he is due for some negative regression with a 4.48 expected ERA, so all this adds up to a recipe for a high-scoring game. Take the over 8.
