The Orioles are 8-2 in their last 10 meetings against the Mariners and are 3-1 in their last 4 meetings in Baltimore.

In this Mariners vs Orioles Prediction, the Mariners are coming as -125 road favorites. The Mariners have the pitching edge with Hancock on the mound, who has just five earned runs across his last four starts, while Bassitt for the Orioles has given up at least three runs in three of his last four starts. On top of that, the Mariners have the second-best bullpen in baseball, so I expect them to get the job done on the road in this one.
