Mariners vs Orioles Prediction

The Orioles are 7-2 in their last 9 meetings against the Mariners, and are 4-1 in their 5 meetings this season. Under is 6-1-1 in their last 8 meetings.

In this Mariners vs Orioles Prediction, the Mariners are coming as -130 road favorites. I don’t trust either pitcher in this matchup, as they have both been mediocre this season, with 4.20+ ERA each. Evans for the Mariners has been weaker at home and last 3+ earned runs in each of his last three starts. On the flip side, Sugano has been playing much better lately, having just one earned run in two of his last three starts. The Orioles are also better against right-handed pitching, so I will take a stab with the home dog in this one, and take the Orioles at plus money.
