In this Orioles vs Mariners Prediction, the Mariners are coming as -145 home favorites. Both pitchers in this matchup have been very good, but Gilbert is more experienced, playing at home and in excellent form, with one earned run or less in three of his last four starts. The Mariners are 7th against right-handed pitching in the last 10 days and have the 7th-best bullpen in baseball, so I expect them to get the job done today at home.
